Rapüh ... Sloth Ratz truly lives up to his name. While his friends, monkey Klimbim and armadillo Gunter, play 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 out! Luckily, Klimbim has a solution: Ratz needs a moth to give him a proper clean! 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 blares through the tree, and suddenly everything spins! Even Ratz! He falls from the tree, right into a big adventure, where he unexpectedly becomes the hero. Because he finds the magical Tempo Phone, whose sound brings everything to a standstill – except for him, Ratz! This makes him, the slowest animal in the jungle, suddenly the fastest! And so he can also 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!.
