Everyone loves Fred, the sloth. Finn, Zoe, and Henry are quite amazed when one day a sloth swings into their kitchen. And what a sloth it is! Fred not only hangs casually from the ceiling lamp but also quickly devours their chocolate pops and is extremely affectionate. When he starts to mimic individual words, it becomes clear to everyone: Fred is part of the family. However, lurking in the bushes is sloth researcher Stockmann. The children must protect their Fred from him at all costs.
