Not to be confused with Pumpkin's death result. Jack o' Lantern was a character who only appeared in the episode "Headless Horseplay". He was introduced waiting on a stump to be picked up by the Headless Horseman, having finally earned the role of being his official Jack o' Lantern. He explained that he had to be in the exact spot at the exact time or he wouldn't get picked up. Before the Horseman arrived, Orange interrupted with a magic trick and accidentally swapped places with Jack using the phrase “Presto change-o switch-o mango”. Jack was left behind, screaming in frustration as Orange got taken instead. He appeared again near the end of the episode, complaining about Shocktober after watching Orange sing "The Song That Doesn't End".
