The Grim Adventures Of Billy and Mandy Season 4 Episode 2 - Wishbones Episode Title:Wishbones.Episode Description:After Grim's robe comes out of the washing machine, Billy and Mandy find Thromnambular, a talking skull with ruby eyes and a number nine imprinted on his forehead. Grim tells them that the skull is a magical artifact imprisoned on Earth that must grant his nine wishes to be free. When Mandy asks Grim why he has not used any of the wishes, Grim tells her that the skull will corrupt the wishes and end up affecting the wisher. Despite this, Billy runs away with the skull and makes the first wish: (1) he wishes to be in an adventure (which parodies Indiana Jones and Jonny Quest), this backfires because Irwin is eaten, which Billy complains about getting him in trouble. After this, Thromnambular is found by different people who each make a wish: (2) Billy's dad wishes he could relive his high school years, but this backfires because he is not popular; (3) General Skarr wishes to rule on high, but this backfires because he asphyxiates in space; (4) Irwin (despite being eaten already in an earlier episode) wishes he was in a hip-hop music video, but backfires because he gets punched by Mandy; (5) Pud'n wishes he had a bunny, but backfires because he is almost killed by it, because "Sometimes Love Hurts"; (6) Nergal Junior wastes his wish by wishing for a wish that wouldn't backfire; (7) Sperg wishes for a way to get into the girls restroom to bully a girl into giving him a large sack of money, this backfires because he is turned into girl and insulted by the other girls for being ugly; (8) Mindy wishes to be a "big star", but this backfires when she is sent into space strapped to a rocket; (9) finally, Mandy tries to auction the last wish, but Grim gets ahead and wishes the kids never found the skull in the first place. This goes back to the beginning of the episode where Billy is staring at the washing machine, followed by Mandy pushing him into it.
