Dráuzio Varíola replaces Professor Cudi and orders students from Fudêncio's class to dissect frogs. Conrado, on behalf of the NGO Green Planet, protests against.
Tropes:
- Free the Frogs: Conrado wants to free them.
- Mother Nature: She appears in the end of the episode and looks like Cudi, plus even has the same Hair-Trigger Temper and Suddenly Shouting traits. She tells the kids that they don't need to care about the frogs used in the laboratory experiments, because they actually do enjoy suffering.
