Mission DescriptionSampo seems to have something to ask of you. Sounds a little sketchy, but honestly? This guy hasn't really pulled one over on you. Not yet, anyway.
- (Approach marked location and interact with Sampo)
- A long time from now, or not so long ago.
- On a day so peaceful it was almost boring, you ran into an old friend.
- Sampo: Hey, (Trailblazer), my dear (bro/
sis)! There you are! Ol' Sampo's been looking all over for you!
Looking for me? What, did you stumble onto some get-rich-quick scheme?
- Sampo: You bet! You're always the first person I think of when something good comes along! Uh... except this won't actually make us rich, haha.
Wait, this isn't illegal or anything, is it?
- Sampo: How could you say that! Words wound, my friend! Has ol' Sampo ever ripped you off... Okay, maybe a few times... But this time, no funny business up my sleeve. I swear.
- Sampo: Come on, let me acquaint you with a new friend. Go on, introduce yourself!
- ???: Dear esteemed Captain Baseballer! I'm the captain of the Interstellar, Swooshy!
Why are they calling me... "Captain"?
- Swooshy: Because on the journey of life, every person is a captain who charts their own future!
- (Trailblazer): True enough. Everyone on the Express is walking our own path.
The Interstellar?
- Sampo: Not a bad name, right? The moment I heard it, I just had to bring them straight to you.
- Swooshy: Captain Baseballer, I'd like to request that you grant us the collaboration rights for Fluffy Across the Blue.
- Swooshy: We want to sell some collaboration art books so the Interstellar can set sail!
- Sampo: ...Well, if we really want to get into it, you should talk to Miss Nihilux about the copyright, but that woman appears when you least expect her, and frankly, we can't really trust her words. Honestly? Talking to you feels way more reassuring.
So what exactly is the Interstellar?
Tell me everything first.- Sampo: Ah, my bad. I put the cart before the horse. Forgot to give my (bro/
sis) here a proper explanation. - Sampo: The Interstellar, now that's a starship worth talking about! Seats 400 passengers, pulls off warp jumps, and cruises at sub-light speed. And the facilities are perfectly complete: a library, a buffet, a gym, and oh, this is the good part, a pretty sizable arcade too!
- Sampo: Long story short, it's a magnificent starship. Just a tiny, tiny bit less cool than your Express.
- Sampo: The only catch? The Interstellar is... an imaginary starship.
- Sampo: The folks who designed it are from a world far, far away. Right about now, they're probably sitting in a classroom somewhere, learning the basics of how to build a starship... you know, addition, subtraction, that sort of thing.
- Sampo: That's right. The Interstellar is a starship that a bunch of kids dream of building one day. Or, to put it a little more bluntly... right now, it's nothing more than a crayon drawing.
- Sampo: For a modest sum, I bought this hefty dream from those kids and carried it all the way to Planarcadia.
- Sampo: And the Wishpower contained within this crayon drawing...
- Swooshy: Turned into me, the captain!
- Swooshy: The one and only purpose of my existence in Planarcadia is to raise funds for the Interstellar... to make it a reality!
So, you need a starship?
Easy. I'll just buy you one.- Sampo: No, no. What we need is for those kids to create the starship themselves. Didn't I just say? They're learning the basics of how to build one.
- Sampo: But going from basic arithmetic all the way up to imaginary number theory? That's gonna cost a pretty penny! And that, my friend, is exactly why Captain Swooshy is here, to drum up the funds.
- Swooshy: So, we're hoping to leverage The Fluffy's popularity to sell some illustrated Astral Express and Interstellar collaboration books. Hopefully, that'll generate more interest for children's dreams.
- Swooshy: This way, the children will have a shot at becoming skilled Navigators like the great Himekat, or brave Trailblazers like the great Baseball Raccoon!
- Swooshy: So, do we have your permission?
Say no more! Go ahead, use whatever you need!- Sampo: Hey now! Sampo knew you were a stand-up pal! We're already done with the book~ Here, have a look, pretty great, huh?
So you act first and ask for forgiveness later?
Considering it's for a good cause, I'll let this one slide!- Sampo: Exactlyyy! Don't sweat the details! It's all for the greater good!
- Sampo: We're pricing the collaboration book at 1 Wishbae. It'll only cost a teeny, tiny prayer each, and that'll set a distant star alight.
- Sampo: See here, my (man/
lady), (Trailblazer). This precious first book is all yours! How would you like to pay?
This is a robbery!
I have to pay for my own collaboration?- Sampo: But when that distant dream finally blooms, everyone there will know: You were the one who planted the very first seed.
Say no more! I'll pay!
- Sampo: Music to my ears, my (man/
lady)!
- Sampo: Music to my ears, my (man/
But I don't have enough Wishbae right now.
- Sampo: That's alright, the two of us will be right here waiting for you~
- (If dialogue was exited)
- Sampo: See here, my (man/
lady), (Trailblazer). This precious first book is all yours! How would you like to pay?
Say no more! I'll pay!
- Sampo: Music to my ears, my (man/
lady)!
- Sampo: Music to my ears, my (man/
But I don't have enough Wishbae right now.
- Sampo: That's alright, the two of us will be right here waiting for you~
- (Obtain paying

Arcadian Token ×1) - Swooshy: Thank you, Captain Baseballer! Every Wishbae we receive is fuel driving our efforts to make dreams come true.
- Sampo: And this energy will surely ignite new hopes and dreams, propelling the Interstellar toward what's coming.
- Sampo: Anyhoo, gettin' late, and old Sampo still has some behind-the-scenes work waiting... Cross-border Wishbae transfers, annoying, amirite!?
- Sampo: Swooshy will be sticking around, so if you've got any other questions, just ask away~
- Swooshy: Swooshy is here to answer all of Captain Baseballer's questions!
- Sampo: I'll be going then. Until next time, (dude/
girl).

Mission DescriptionThe sky is vast and boundless, and so are the wind-like dreams of humanity. So how could anyone claim that humans will never fly? Gravity is just gravity, after all.
"Countless shooting stars streak across the night sky... If you can pick the right one, it will carry your wish to thousands of distant worlds."
- (Approach marked location)
- (Trailblazer): Wonder how Sampo's fundraising campaign is going? Better head over to Swooshy and check.
- Invalid Transclusion
- (Interact with Swooshy)
- Swooshy: Captain Baseballer. I appreciate your support for the Interstellar! Is there something I can help you with?
Everything going well lately?
- Swooshy: Very well, thanks to you! Lots of people bought our illustrated collaboration books, so those kids out there will have much better learning resources now.
- Swooshy: Even though they still have a long way to go before they can actually build the Interstellar, time is on our side~
- Swooshy: Thank you again, Captain Baseballer!
- What are you going to do when the starship is completed?
- Swooshy: An imagenae like me can't actually travel in the Interstellar, obviously~
- Swooshy: But that's alright. I was born from the wishes of countless children. And now, I've come to Planarcadia, carrying those very wishes...
- Swooshy: When the day comes for the starship to set sail, the children will carry my wishes to a thousand worlds and beyond.
- Swooshy: That is enough for me! We wispae are pretty easy to please!
Nothing else for now. See you around!
- Swooshy: See you next time!

Trivia
- This mission is an easter egg referencing the real-life Fluffy Across the Blue charity project. In Volume 2 of the project's charity video series, children from rural areas of Yunnan Province were brought to the Jiuquan Satellite Launch Center, where they watched the live launch of the Shenzhou 23 spacecraft on May 24, 2026.
- In the charity video, the Yunnan children are represented by a red panda Fluffy cartoon character, an animal native to Yunnan.
- The items

Letter Sent Across the Stars and 
Setting Sails Among the Stars Picture Book are based on the Yunnan children. The picture book has a series of drawings depicting their dreams, which are randomly distributed to players.
