The Lost Button

Last updated 2025-09-13

The Lost Button is a random Adventure Mission on the Astral Express. There is a time limit of 4 hours once the mission starts.

Steps

  1. Find Pom-Pom's button
  2. Return the button to Pom-Pom

Gameplay Notes

  • The button is found on the ground next to the plant near the Omni-Synthesizer. Occasionally, an Astral Express visitor may be standing at that location, obscuring the glint the button gives off.

Dialogue

Pre-Mission

(Talk to Pom-Pom)
Pom-Pom: (Trailblazer)...
Icon Dialogue Quest What's wrong?
Pom-Pom: Darn it, darn it... If Pom-Pom can't find the button soon, Pom-Pom'll look all disheveled in front of the passengers...
Icon Dialogue Arrow Too late. I already saw you.
Icon Dialogue Arrow Want a hand looking for that?
Pom-Pom: Argh!! (Trailblazer), where'd you come from? You freaked Pom-Pom out!
Pom-Pom: Pom-Pom's not sure where, but my button's fallen off somewhere... Pom-Pom did sew it on my uniform last time. But now my clothes have this big open gap, and it's simply embarrassing...
Pom-Pom: Pom-Pom has to find that button before any other passengers see me like this! Please, (Trailblazer), help Pom-Pom find it!

(Investigate chair)
Icon Dialogue Loupe Investigate
You discover a round thing and draw closer to inspect... It's a bottle cap, not a button!
(Trailblazer): (This must have fallen down while getting a drink. So throw it in the trash!)

(Investigate counter)
Icon Dialogue Loupe Investigate
You discover a square thing and draw closer to inspect... It's a note, not a button!
(Trailblazer): (Looks like something March 7th left behind... Perhaps she deliberately stuck it there as a decoration?)

(Investigate floor by Omni-Synthesizer)
Icon Dialogue Loupe Investigate
You discover a sparkly thing and draw closer to inspect... It's Pom-Pom's button!

Return the button to Pom-Pom

UI Adventure Mission Step Description

Return the button you found to Pom-Pom. Speaking of which... Why would a button fall off just like that?
(Talk to Pom-Pom)
Pom-Pom: (Trailblazer)...
Icon Dialogue Quest What's wrong?
Pom-Pom: Could it be that Pom-Pom's been eating a little too much these days, and the button's popped off my fat belly... No way! Absolutely no way! Pom-Pom only ate a little.
Icon Dialogue Arrow (Give Pom-Pom the button)
Pom-Pom: Oh, it's my button! Now Pom-Pom just needs a needle and thread to stitch it all up... Dum-dee-do! All done!
Pom-Pom: Oh... Pom-Pom feels like it's getting harder to breathe. How did Pom-Pom's clothes just get tighter...
