With All This Panic

On the day of his graduation at a school event, Paquito must read his farewell speech in front of the entire school, which makes him extremely nervous. When it's time to speak on stage, a strange creature comes out of Paquito's stomach. The Creature torments Paquito throughout the day and follows him on the way to his house.
