Pocoyo sees Loula chasing her tail and has a fit of giggles. No matter how hard he tries, he can't contain his laughter. Because of this, every time he is with his friends, a disaster occurs because he cannot control his laughter or movements. His friends are a bit annoyed with him, but little by little they can't help but get infected with Pocoyo's laughter, and everyone, including the Narrator, ends up in a fit of giggles.
