Adventure Time
The cool thing about Adventure Time—well, one of the many cool things about Adventure Time—is that it slowly became clearer that was seemed to be a fantasy land of shape-shifting dogs and sentient candy people was Earth after the “Great Mushroom War” mutated just about everything but a small group of humans. It’s a slow burn that begins when the addled Ice King says he picked up his magic crown in Scandinavia, something that could easily be dismissed as a gag. Instead, the show eventually shows what happened to turn Earth into Ooo, leading to flashbacks that serve as the show’s best and most heartbreaking episodes like “Remember You.”
