Rapüh ... Sloth Ratz truly lives up to his name. While his friends, monkey Klimbim and armadillo Gunter, are playing ball, Ratz prefers to close his eyes. He just can't sleep, though, because it itches! And scratching is so exhausting – Ratz's arms are only meant for hanging around! Luckily, Klimbim has a solution: Ratz needs a moth to give him a thorough cleaning! And literally in a flash, moth Mimi moves in with Ratz. But oh dear, Mimi not only messes up Ratz's fur but also his entire life! Early in the morning, loud music blasts through the tree, and suddenly everything spins! Even Ratz! He falls from the tree, right into a big adventure where he becomes the hero. Because he discovers the magical Tempo-phone, whose sound brings everything to a standstill – except for him, Ratz! This way, he, the slowest animal in the jungle, suddenly becomes the fastest! And he can then save his friends who are threatened by jaguar Morto and snake Schiela. If that’s not a reason to turn up the radio and throw a big party!.
