(UPDATED 9/18: Added Brusha, Yatta, Blot, Dyle, and the Easter toons)
Dandy had started an ichor operation in the abandoned museum where the toons needed to survive twisteds of themselves and go on an elevator to descend to lower floors that the twisteds were on. Twisteds were infected with ichor, which makes their eyes bloodshot, their memories fade, and makes you bloodthirsty. Dandy sold items in exchange for their cooperation every two floors. The biggest twisteds were the mains and lethals- Astro, Shelly, Vee, Bobette, Pebble, Dyle, Dandy, and Sprout. They were also quite rare.
Soon the ichor operation ended due to a cure being found. After all the twisteds were cured, they were put into rehab to stabilize their mental health again. The cure didn't fix EVERYTHING, after all. Some toons still experienced moments of aggression. Like Glisten, his ego was completely gone and he was extremely clingy now. Some toons actually used eachother for comfort.
((You can be a non-infected toon who works there, or you can be a toon in rehab! :D))
