Roblox | Undertale AU Monsters Battles | Secret badges and Gaster preview

In this video I show how to get the Gaster badges and where you find Gaster and Void gaster. I also show the attacks of Gaster! Comment down below if I should make a video about Void gasters attacks, or maybe another monster?
