Basically, Shelly snaps after years of being ignored, abandoned, and hated before creating a "game show" where the Toons go down each floor and one by one, get killed in brutal ways until no one is left (which happens on a live show that children and parents are watching) :3

I only have death ideas for Shrimpo and Goob:

Goob is tied up and tortured before getting crushed under a bookshelf, and Shrimpo is skinned alive and gets his legs and arms cut off before being cooked and eaten

Note: I also had an Au idea where Shelly becomes a Cult leader but I'm not really interested in it rn so if yall wanna make your own Au based on that you can :P
