Dialogue

Icon Dialogue Event Head to Bootopia again

To completely resolve the anomalies caused by the faulty chip affecting Eous, Dialyn suggested that Eous return to Bootopia to continue scavenging supplies and search for a solution. So the Bangboo decided to put their heads together once more and venture back to Bootopia for another adventure...
(Talk to Marcel Specialist again if exited)
Marcel Specialist: Manager, Eous, perfect timing! I just remembered something super important I forgot to mention earlier... Ahem, but don't you dare go reporting this to Miss Dialyn!
Marcel Specialist: While fixing up Eous' Chip, I found out it can also connect to our Marcel Group's internal Bangboo upgrade system!
Marcel Specialist: You can spend Marcel Coins to unlock Bangboo Talents in the upgrade system and make Eous even stronger!
Icon Dialogue Talk Marcel Coins?
Icon Dialogue Talk Where am I supposed to find them?
Marcel Specialist: That's the Bangboo currency used internally by the Marcel Group. While exploring the amusement park as Eous, keep an eye out for supplies dropped by Bangboo visitors, you're bound to find some in there.
Marcel Specialist: Oh, by the way! Some of the rarer Talents require specific Supplies to exchange for them... but I'm sure that won't be a problem for Eous.
Marcel Specialist: To help you upgrade your Chips, I'll be sticking around the video store while you're out exploring the island. Come see me anytime you need help.
Marcel Specialist: Whenever you wanna head to the island, just come find me. So, you ready to head over to Bootopia?
Icon Dialogue Event Eous is ready to go.

Icon Dialogue Event Tracked Chat with Dorothy

Looks like Dorothy, Bootopia's tour guide, needs a hand with something. I should see what's up!
(Enter Bootopia)
(Open Retreat Time and Equipment Durability tutorial)
(Talk to Dorothy)
Dorothy: Ehn-ne, ehn-ne-ne! (Eous, good to see you again! Ever since you helped me find those multi-function power banks, I've scoped out the whole area! If you ever need a hand, just hit me up!)
Dorothy: Nhe-nha, en nhu-nhe. (Oh right, I've got some bad news. The Hollow disaster triggered the park's defense system, and multiple attraction areas are now on lockdown. Our access chips are just standard clearance, so there's no way we're getting in.)
Icon Dialogue Talk Not even if you're the tour guide?
Icon Dialogue Talk I wanna know how to get promoted.
Dorothy: Ehn-ne... Ehn-ne. (The Hollow hasn't completely wrecked our employee management system yet, so I'm thinking... if we collect enough positive reviews from visitors, we can boost our clearance and unlock more sealed-off areas.)
Dorothy: Nhu-nha, ehn ne? (Eous, you wanna come with me to rescue those tourists in trouble? If you do, we'll definitely rack up tons of Positive Reviews!)
Icon Dialogue Talk Let's go together.
Dorothy: Nhe nha en! (Stay close then — I think I heard someone calling for help near the docks!)
Icon Dialogue Event Tracked Search for the missing tourist

Dorothy and I heard a Bangboo tourist cry for help on the beach. I better help, and quick!
(Ongoing)
Dorothy: Ehn-ne~ (Let's go to the port first. Over here~)
(Approach the docks)
(Open Obstacles & Bombs tutorial)
(Ongoing)
Dorothy: Ehn-ne~ (Use bombs to blow up all obstacles~)
(Approach the islets)
(Ongoing)
Dorothy: Ehn-ne! (Eous, you're amazing!)
Eous: Ehn-ne... (Seems the bombs sent the barriers in the wrong direction...)
(Approach the marked location)
Dorothy: Nhu ne... (That's gotta be him calling for help... Let me poke it! Huh, no response again...)
Dorothy: Ehn-na, nhe-na? (Their components and circuits might've gotten knocked outta place from the impact. Eous, can you repair Bangboo?)
Icon Dialogue Talk I've watched Master repair Bangboo before.
Icon Dialogue Talk I can give it a try.
Icon Dialogue Event Tracked Try to repair Sharkboo

Sharkboo's mechanical parts and circuits got knocked out of place from the impact. I should try fixing them up.
(Interact with Sharkboo)
It looks pretty rough. Want me to fix it up?
Icon Dialogue Talk Fix it now
(Enter "Polarity Calibration" Yellow Bar Node)
Icon Dialogue Talk I have stuff to do.
(After completing Polarity Calibration)
Sharkboo: Nhe-nha...? (Where am... who are you...?)
Dorothy: Ehn-nhe, na en... (Hello, sir. We're part of the rescue team. We apologize, but the Hollow incident is still in progress. Please follow directions and evacuate Bootopia in an orderly fashion...)
Sharkboo: Nhe-nhu! Ehn-na! (What are you rambling on about?! I am the lord of Atlantis!)
Icon Dialogue Talk ...It suddenly perked right up!
Icon Dialogue Talk But not in a normal way...
Sharkboo: Nhe-nhu, ehn-na! (Awaken, my loyal subjects! Swear your allegiance to me here and now, and aid me in restoring our great empire!)
Dorothy: Ehn-nhe... Nhu-na en... (Oh no! This visitor seems to be affected by a chip — their Logic Core is in cognitive chaos!)
Icon Dialogue Talk This feels way too familiar!
Icon Dialogue Talk This is about the chips again...
Dorothy: Ehn-nhe? nhe-nha ehn... (Eous... You didn't know about this? To ensure Bangboo visitors can have a fully immersive and joyful experience at the amusement island, we provide chips containing special role-playing identity data for visitors to use.)
Dorothy: Nhe-ehn... (But the Bangboo expert in charge of this program, Master Hollowell, is currently MIA, so looks like no Bangboo's gonna be able to fix the chip problem...)
Icon Dialogue Talk Master Hollowell...
Icon Dialogue Talk Now that's some crucial intel!
Dorothy: Nhe-nhu ehn. (Putting that aside for now, Eous, you got any way to convince this confused tourist to leave?)
Sharkboo: ...Nhu-ehn! Nhe-nha!(...Let go, quit pulling me around! I must remain here and find a Bootopia Watch to restore my kingdom!)
Dorothy: Nhe-nhu... (Looks like he won't cooperate unless we find him a Bootopia Watch. But... I don't recall seeing any watches around here.)
Dorothy: Ehn-ne, ehn-ne? (Eous, when you leave Bootopia, could you look for a Bootopia Watch in the city?)
Icon Dialogue Talk I know someone who works at Marcel.
Icon Dialogue Talk Maybe I can ask him.
Dorothy: Nhe-nhu! Ehn-na ehn! (That'd be awesome! I'll be right here waiting for you!)
Icon Dialogue Event Tracked Activate beacon

To make the next exploration easier, I should take Dorothy's advice and activate the beacon first.
(Ongoing)
Dorothy: Ehn-ne. (Let's go activate the beacon before we leave.)
Dorothy: Ehn-ne~ (Eous, follow me~)
(Interact with Activate Teleporter)
(Open Bootopia Teleport Beacons tutorial)
Dorothy: Ehn-ne... Ehn-ne-ne! (Now that the beacon's activated, you can start exploring the island from right here next time. That'll save a ton of time!)
(Open Find the Evacuation Point tutorial)
(Ongoing)
Eous: Ehn-ne... (I'm feeling a little dizzy... It's about time to retreat.)
Icon Dialogue Event Tracked Go back to Sixth Street and ask the Marcel specialist about the parts

According to Dorothy, the Bootopia Watch that Sharkboo wants can't be found nearby... Maybe after returning to the video store, I can go to the nearest Marcel workstation and ask the specialist where to find the parts?
(Talk to Marcel Specialist)
Marcel Specialist: Eous, I was just looking for you! Do you guys remember? Eous helped out a Bangboo staff member who does scare performances before.
Marcel Specialist: After he left the theme park, he volunteered to come help with Eous's search and rescue efforts. I bet he'll be here real soon!
Booltergeist: Nhe-nha ne... (Actually, I've been standing here for quite a while now...)
Marcel Specialist: ...Huh?! Oh, I totally didn't notice!
Booltergeist: Nhu, nha-ehn ne. (It's fine... I'm used to it. Since I go unnoticed, I can always pop out and scare people during performances... but when a Hollow hits, no one remembers to save me...)
Booltergeist: Nhe~ Ehn-na~ (Only Eous and his companions helped rescue me from that dangerous island... So, I specifically requested a transfer to come here and provide Eous some assistance~)
Booltergeist: Nhe-nha en... (From now on, Eous can access the Marcel employee-exclusive store through me anytime to buy any needed supplies.)
Icon Dialogue Talk I got something I wanna trade!
Icon Dialogue Talk It's Sharkboo's commission.
Booltergeist: Nhu-nha~ (Glad I could help.)
Booltergeist: Ehn-ne! (Eous, keep exploring Bootopia for now!)

(Bubble)
Fairy: Head over to the Storage and check it out.
Fairy: Sell supplies to get Marcel Coins for Store purchases.
Fairy: Let's head back.
Fairy: "Exclusive Supply" function now unlocked.
Fairy: You can buy supplies here.
Fairy: These are the supplies Sharkboo needs.
Fairy: Go ahead and buy them.
Icon Dialogue Event Tracked Head to Bootopia again

Got enough supplies. Time to head back to Bootopia and hand everything over to Sharkboo.
(Enter Bootopia)
Icon Dialogue Event Tracked Talk to Sharkboo

Sharkboo's chatting with Dorothy about his dream of "kingdom restoration." If I want to know what his plans are, I can talk to Dorothy. She's right there next to him!
(Talk to Sharkboo)
Sharkboo: Nhe, en nha. (Have the Bootopia watches I requested been prepared?)
(Submit Bangboo Fun Watch Bangboo Fun Watch ×1)
Sharkboo: Nhu nha! Ehn-nhe... (Excellent, I am fully prepared to reclaim my nation! However, there's still a bunch of vile Monsters occupying my royal chambers...)
Sharkboo: Nhu-ehn! (Once we wipe them out, our kingdom's restoration will be at hand!)
Icon Dialogue Talk This restoration storyline goes on forever...
Icon Dialogue Talk Looks like Your Majesty isn't ready to leave just yet.
Dorothy: Ehn-ne... ehn-ne... (Master Hollowell's role-playing chips are always this immersive! Eous, if you wanna keep helping this tourist, I can guide you to the place he mentioned.)
Icon Dialogue Talk Seeing as we're here...
Icon Dialogue Talk Let's go!
Icon Dialogue Event Tracked Head to the "palace" and clear out the Ethereals and turrets

Got Sharkboo's suggestion to go to the "palace" he mentioned to clear out the obstructing Ethereals and turrets.
(Ongoing)
Eous: Ehn-ne! (I know! We need to blow up the gate!)
(Ongoing, after entering the castle)
Dorothy: Ehn-ne... (Eous... teach me how to beat Ethereals next time...)
Eous: Ehn-ne! (But I only know how to hammer...)
Dorothy: En-nah. (That's what I like about you...)
Dorothy: Ehn-ne. (I mean, I love swinging a hammer...)
(After defeating all turrets and enemies)
Sharkboo: Nhu-nhe! (Cleanup complete! Even the air's feeling fancy now!)
Icon Dialogue Talk Your Majesty's getting way too into character...
Icon Dialogue Talk What's next?
Sharkboo: Nhe ne, nhe-nhu na! (The auspicious hour has arrived! Let the sacred ceremony begin!)
Dorothy: Ehn-ne... Ehn-ne! (I'm quite familiar with Bootopia, and I know a bit about the ritual... Besides, I've already looked around and I think I've figured out this "Majesty's" plan.)
Dorothy: Nhu, nhe-en. (Supposedly, if those evil forces around the altar that stand in the way of restoring the kingdom are cleared out and the ritual is activated, Atlantis will return.)
Icon Dialogue Talk ...I have no idea what that means.
Icon Dialogue Talk But you're the guide, so I'll follow your lead.
Dorothy: Nhu ehn, na! (You don't have to understand. Just come with me and you'll see!)
Icon Dialogue Event Tracked Talk to Sharkboo

All the Ethereals have been wiped out... Time to check in with Sharkboo and see what's next
(Talk to Sharkboo, if Bootopia was left)
Sharkboo: Nhe ne, nhe-nhu na! (The auspicious hour has arrived! Let the sacred ceremony begin!)
Dorothy: Ehn-ne... Ehn-ne! (I'm quite familiar with Bootopia, and I know a bit about the ritual... Besides, I've already looked around and I think I've figured out this "Majesty's" plan.)
Dorothy: Nhu, nhe-en. (Supposedly, if those evil forces around the altar that stand in the way of restoring the kingdom are cleared out and the ritual is activated, Atlantis will return.)
Icon Dialogue Talk ...I have no idea what that means.
Icon Dialogue Talk But you're the guide, so I'll follow your lead.
Dorothy: Nhu ehn, na! (You don't have to understand. Just come with me and you'll see!)
Icon Dialogue Event Tracked Activate three ritual devices

Based on Sharkboo's guidance, I should team up with Dorothy to explore the nearby area, find the mysterious devices that can be used for "kingdom restoration," and activate them one by one!
(Ongoing)
Dorothy: Ehn-ne? (The device that activates the ritual... Where is it?)
Dorothy: Ehn-ne. (It should be nearby...)
(Activate the first Unknown Array's "Array Base")
Dorothy: Nhe-nha! Ehn en-nhe... (That's it, activate the device! Just two more spots to go...)
(Activate the second Unknown Array's "Array Base")
Dorothy: Nhu-nha. Ehn-ne! (Only one left. Quick, come with me!)
(Activate the last Unknown Array's "Array Base")
Dorothy: Ehn-nhe... Ehn-nhe-nhe! (Well done Eous. That's all the devices activated!)

(Cutscene plays)
Sharkboo: En-neh! (Oh, lost kingdom!)
Sharkboo: En-nuh! (Return to your former glory!)
(An island arises from the sea)
Sharkboo: Enneh, enna! (Whoa... That actually summoned a real island!)

Sharkboo: Ehn-na?! (The island... it's actually rising?! The legend of Atlantis... it's real?!)
Icon Dialogue Talk Even you're doubting yourself?
Icon Dialogue Talk I thought you were so sure about it.
Sharkboo: Nhe... Nhe-nhu! (Ahem... who gave you permission to question your king...? Let's get to the point! Next, we're taking down the Deep Sea King holed up in Atlantis.)
Sharkboo: Nhu-en. (I'll scout out the island first. You lot get ready, then hurry over to back me up.)
Icon Dialogue Event Tracked Return to Sixth Street and report the progress to the Marcel specialist
(Optional) Keep exploring Bootopia

It's about time to head home and regroup. Once I'm back at the video store, I gotta report the progress to the Marcel specialist. Who knows, I might get some useful tips!
(Ongoing)
Eous: Ehn-ne! (We made a lot of progress today. Let's get out of here!)
(Talk to Marcel Specialist)
Marcel Specialist: Eous is back. What's the progress on Sharkboo's end?
Icon Dialogue Talk Things are going smoothly.
Eous: Nhu-nhu, nha-ehn ne! (We followed Sharkboo's plan, and after completing the ritual, we couldn't believe it — Atlantis actually rose from the water!)
Eous: Nhu-nhe, ehn ne na! (Next up, Sharkboo and I are gonna take on the legendary Deep Sea King!)
Marcel Specialist: Eous better be ready for this one. The Deep Sea King sounds like no joke. Make sure those talents are set up, grab some items from the shop, and be fully prepared before going in.
Icon Dialogue Talk Don't worry!
Eous: Nhu-nha ne! (Got it! I'll go get ready right now.)
Icon Dialogue Event Tracked Head to Bootopia

To get a positive review from Sharkboo and boost Eous's Marcel employee privileges, I gotta head back to Bootopia soon and see if we can continue to help Sharkboo.
(Enter Bootopia)
Icon Dialogue Event Tracked Look for Sharkboo

Back at Bootopia. First up is to find Sharkboo, the Bangboo tourist. He should still be around the island area.
(Approach the island)
Eous: Ehn-ne? (Where did the descendant of Atlantis go?)
Icon Dialogue Event Tracked Talk to Dorothy

To find the powerful Ethereal, the Deep Sea King, I need to first find Dorothy and have her lead the way.
(Idle)
Dorothy: Na-nhu! (Eous, I've been waiting forever!)
Dorothy: Nhu-na! (We've got the intel on the Deep Sea King!)
(Talk to Dorothy)
Dorothy: Ehn-ne. ("His Majesty" has been waiting on the island for ages. If you're all set, shall we go assist him in taking down the Deep Sea King?)
Icon Dialogue Talk I'm ready!
Icon Dialogue Talk I still need to prepare...
Icon Dialogue Event Tracked Defeat the Deep Sea King

It's time to help Sharkboo take down the powerful Ethereal, the Deep Sea King!
(Defeat the Deep Sea King))
Icon Dialogue Event Tracked Talk to Sharkboo

Defeated the powerful Ethereal, Deep Sea King. Time to collect that positive review from Sharkboo.
(Talk to Sharkboo)
Sharkboo: Nhe... nhu na! (Unbelievable... thou hast truly accomplished it!)
Dorothy: En-nah! En-nah! (Amazing, Eous! That spinning kick was absolutely perfect! I've never seen a Bangboo swing a hammer like that before...)
Icon Dialogue Talk I just happened to find the weak spot, that's all.
Icon Dialogue Talk Combat isn't exactly my strong suit.
Sharkboo: Nhe-nhu, ehn-na. (Now that even the mightiest lord of these waters has been subdued... I acknowledge you as heroes. From here on, we stand and fight together.)
Icon Dialogue Talk So you're finally coming with us.
Icon Dialogue Talk Mind dropping a positive review?
Dorothy: Ehn-ne, ehn-ne. (Your Majesty, it's okay if you don't understand. Please hand me your visitor pass, and I'll do it for Eous.)
With Dorothy's help, you got a positive review from the visitor, plus a little thank-you gift...
Sharkboo: Nhe-nhu ne! (Now that your wish has been granted, there's no time to waste. Let's head straight for the remaining islands!)
Icon Dialogue Event Tracked Leave Bootopia
(Optional) Keep exploring Bootopia

It's about time to head home and regroup. Once I'm back at the video store, I gotta report the progress to the Marcel specialist. Who knows, I might get some useful tips!
(Talk to Sharkboo again, optional)
Sharkboo: Ehn-ne ne. (That Bangboo who came with you earlier... Eous, was it? What a true hero. I wonder which empire he hails from, and which king he serves under...)
Dorothy: Nhe, nha-ehn ne. (You wanna hear how we met again? So at first, we ran into each other at the entrance to Bootopia.)
Sharkboo: Nhe-nhu? (You've already told me this story.)
Dorothy: Nhu-nha, ehn ne... (The details are different this time though. That day, I remember Eous' scarf had a frayed edge sticking up...)
Sharkboo: Nhu ne. (You already mentioned that detail, though.)
Dorothy: Nhe-nha, ehn ne... (And then, I asked him to help me find three multi-function power banks...)
Sharkboo: ...Nhe nhu! Ehn ne! (...Would you listen to me!)

(Leave Bootopia)
Marcel Specialist: How's Eous doing with the recent search and rescue at Bootopia? Collected any positive reviews from the tourists?
Eous: Nhe-nhu ehn na! (With the tour guide's help, Sharkboo gave me a huge positive review... and it's already logged in my employee chip!)
Marcel Specialist: Nice job, Eous! You're amazing! I didn't expect you to handle Sharkboo's commission so easily!
Marcel Specialist: By the way, did you guys pick up any intel on the Chip modifiers from the staff?
Icon Dialogue Talk Do you know Hollowell?
Icon Dialogue Talk We think he's suspicious.
Eous: Ehn-ne, ehn-ne. (Master's right. I heard from the tour guide Dorothy that the person in charge of maintaining all the various Bangboo Chips on the island is none other than the so-called Master Hollowell.)
Eous: Nhu-nha, en ne? (Mr. Specialist, have you heard of him?)
Marcel Specialist: Hollowell... that name... could it be THAT Hollowell?!
Marcel Specialist: Sorry for losing my composure. It's just I recall a specialist in Bangboo manufacturing named Norma Hollowell.
Icon Dialogue Talk I know her!
Marcel Specialist: But as far as I know, she's been locked up in her lab conducting research lately, and there's no record of her visiting the island recently...
Marcel Specialist: In any case, this intel's important. Don't worry everyone, I'll look into it!
Marcel Specialist: Oh right, thanks to Eous's recent explorations, we've gathered a ton of fresh data that can help calculate Hollow routes. The search and rescue team from Marcel can head back in now.
Marcel Specialist: But Bootopia's management system is still out of control, with tons of areas forcibly locked down, so no one can get in...
Marcel Specialist: We're hoping Eous can keep helping the staff and visitors inside, look for supplies, tap into the amusement park's internal network, and increase employee clearance levels... That'll unlock those sealed-off areas.
Icon Dialogue Talk You can trust Eous.
Eous: Nhe-nha, ehn nhe! (I'll keep at it!)

Tutorials

Retreat Time
File:Tutorial Retreat Time 1.png
Retreat Time
Each exploration has a time limit.
If you don't evacuate before time runs out, it counts as a failed evacuation, and you'll lose all the supplies you collected during that run.

File:Tutorial Retreat Time 2.png
Equipment Durability
Each exploration of the island consumes 1 Durability from the equipment you bring.
Once Durability hits zero, the equipment will be considered Damaged. Using damaged equipment will greatly reduce Eous' combat effectiveness.
Consider selling your damaged equipment.
Obstacles & Bombs
File:Tutorial Obstacles & Bombs 1.png
Attacks or bombs can destroy certain obstacles on the island to create new paths. Bombs can be obtained from chests. Once equipped in your equipment slot, press Bangboo Bomb to launch a bomb ahead, dealing DMG to enemies and obstacles within range.
Bootopia Teleport Beacons
File:Tutorial Bootopia Teleport Beacons 1.png
Multiple teleport beacons are scattered throughout Bootopia. Unlocking Teleport Beacons: Find these teleport beacons and interact with them to unlock them.
Spawn Locations: When entering Bootopia while tracking a mission, Eous will prioritize spawning at the teleport beacon closest to the mission target.
Teleport Function: Unlocked teleport beacons have a teleport function. You can find these teleport beacons on the map interface and teleport to a location next to the designated teleport beacon.
