The day starts like any other in Oswaldo's life. He wakes up, gets dressed and goes to school. Only... there's no one at school!! He is completely alone. Without anyone. At school. Wow!! Of course, Oswaldo decides to mess up everything he can: the chemistry lab explodes, plays with toilet paper and even surfs through the corridors. Until he feels bored being so alone and with no one to talk to. He then gets a Tobias sock and they start talking (well, it's actually him talking to himself) Suddenly the school is completely full of friends made of random things: a broom turns into Leia, the garbage can is Medeiros, a ball with a face is director Marilu, and Oswaldo is living a complete episode of her private show, full of drama, romance, action; all inside your crazy little head. He has a super cool day, but when he gets home he finds it all happened simply because it was Saturday.
