STACTIC/FLASH WARNING SPOILER WARNING SOUND CONTAINS THE WORD M*RDER his mom is the red (left) one and the dad is the blue (right) one bills backstory is sooooo sad and messed up SPOILERS IF YOU DON'T WANT SPOILERS DONT READ THIS PART Basicly bill could see the 3rd dimension in a 2d world everybody (including his parents but they tried to help) thought he was insane. so bill was bullied. He wanted to show everybody the third dimension too so for some reason he thought if he set the sky on fire people would see the 3rd dimension. IDK if it worked but the fire burned down Euclidia (his home dimension) from the inside out. at the last second he tried to grab his mom witch he did but she burned in his hands(I think that part happened it was in the video but it might've not actually happened). Hes in a jumpsuit cuz before stan punches him into ablivion he says "A-X-O-L-O-T-L MY TIME HAS COME TO I INVOKE THE ANCIENT POWER I MAY RETERN" backwards so the axolotl sends him to interdemensional therapy and when he is finish he can come back as a worm fungi or something else(I forgot them). but instead of working on his isseus he tries to escapes.
