It's a party day at school, but the focus of the students is the bathroom, occupied by Medeiros, who makes Geovan his hostage. Oswaldo proposes to help, being the rescue negotiator, but even after researching foods that bind and release, he still doesn't understand what might be happening, until he finds out with Leia's help that the problem is a new haircut - and ugly - from Medeiros. Tobias solves the problem with his newest wig made of beards and tufts of hair, and everyone heads off to the party.
