The Grim Adventures of Billy & Mandy Season 4 Episode 12
“The Firebird Sweet”
When Billy buys a new cereal, a phoenix emerges from the box and attaches to his head, annoying everybody. Since the phoenix cannot be removed because it revives every time it is destroyed, Billy, Mandy and Grim seek help by going to the factory where the cereal is produced, which is run by Eris, the goddess of chaos. Mandy tricks the phoenix into leaving Billy and attacking Eris instead. It is revealed that all the events were really an episode-within-an-episode.
“The Bubble with Billy”
When Billy desperately wants chewing gum at school, Grim gives him a bottomless gumball machine, but warns him not to swallow the gum. Billy ignores Grim’s warning and starts swallowing the gum, causing him to constantly burp bubbles that fill the entire city. Mandy and Grim try to get Billy to cough the remaining gum that he has in his stomach, but instead Billy swallows the entire gumball machine. Billy coughs huge amounts of gum all over the city and ends up with a supernatural rash from another interdimensional world.
