Trashy Date

Trashy Date is the twenty-first episode of Undertale on Steam Train.

Intro
The video starts with a live action commercial. Arin approaches Barry and asks him what he’s doing on his phone. As he brings up anime, Barry cuts him off, not wanting to hear another ad. Arin then viciously points at Barry’s phone asking what’s on it. Barry then gives a pitch for the free mobile game Best Fiends. Arin creepily leaves to get his phone and download the game.

Game Progress
Ross and Barry return to the game to get a different ending by killing Flowey. Their character ends up going on a pretend date with Alphys. The date ends with Alphys professing her love to Undyne.
