Oswaldo is sad. He was mocked in art class when he presented his artwork "Joinha Duck" (he's a duck, and he pulls a stick!) Depressed, he wanders aimlessly around the school until he hears a very happy song coming from one of the classrooms of class. He is intrigued and discovers something very amazing: it's the nursery room! So Oswaldo decides to join the preschool, where all classes are taught by Furão Listradinho, a Barney-style character on TV. Oswaldo LOVES it: he gets a little gold star for every correct answer, they take a nap every day in the middle of class and he can even wear some super cool shorts that you never need to go to the bathroom again! Kindergarten life is much nicer, he even convinces Tobias to join him in the fun. That is, fun until Oswaldo ran into the wire and accidentally broke the classroom TV. Suddenly all babies turn into drunk zombies, attacking everything they see in front of them, even Tobias was drunk.
