| Character Information
After Richard gave Gumball the Gamechild, he started to play with it and gets mysteriously transported to his room. Darwin and Anais team up with Gumball (who nicknamed himself MYBUTT) on a quest to defeat the Gamechild.
After battling a monstrous flower and completing several minor quests, Gumball, Darwin, and Anais encountered the Van Shopkeeper, who tells the heroes that the Gamechild is the true enemy and is responsible for trapping Gumball, Darwin, and Anais in a RPG called Inverted Paradox. They confront the Gamechild, who took the form of a tentacle demon. They battle the cursed console, but it seems to overpower the Watterson siblings, nearly defeating them. Gumball then summoned several of his friends and parents to defeat the Gamechild. The Gamechild was defeated for good when it was vaporized by Richard's secret weapon.
