The Grim Adventures of Billy and Mandy Season 2 Episode 8

Grim For a Day / Chicken Ball Z / The Halls of Time

"Grim for a Day" After a lousy night for Grim, Billy and Grim argue about who has the hardest time, the kid or the Reaper of Souls. Mandy proposes they switch places for the day to find out. Grim seems to be having a good time, acting like a silly kid, while Billy is bored waiting for his old victim, Mr. Voorhees, to open the door. Billy transforms into a short skeleton, while Grim transforms into a taller version of Billy. "Chicken Ball Z" Grim's refusal to help Mandy win a karate tournament, and the $50,000 prize it promises to the winner, leads her to a curio shop, where the shopkeeper, Kuan Ti, gives her an ancient "Chicken Ball" which, when eaten, allows her to become a great fighter. Mandy easily wins the tournament and does not care about the money anymore, only about fighting. It turns out Kuan Ti is actually Eris in disguise, and this was just another of her schemes to create chaos. Seeing how he has a chance to get rid of the kids and finally be free, he tries to take advantage over this by making Billy a superb fighter too, so he and Mandy can fight ferociously to the death until the entire arena is destroyed. With both still alive, Mandy still demands the prize money, which she uses to buy Hector Con Carne's Bunny Island. "The Halls of Time" After missing on a school trip, Grim takes Billy, Mandy and Irwin to the "Halls of Time" for a tour. There, Billy and Irwin mess the hourglasses that symbolize each person's lifespan. When they leave, they accidentally leave their own hourglasses, including Grim's, upside down, resulting in the group getting younger as time passes. Grim allows the kids to disappear by going before birth, but he cannot restore his own hourglass to its correct position and he disappears too.
