Dráuzio Varíola and his team create, through experiments, a Neanderthal boy, whom they call Lapedo. Nine years later, Lapedo escapes and remains on the loose. He arrives at school, where he is mistaken by Professor Cudi for a new student, named Juquinha by the kids. Because of his strength, he becomes popular with students.
Tropes:
- All Cavemen Were Neanderthals: Juquinha is an artificial neanderthal. Although he's small due to being a kid, he's still strong and dumb, and can't say full sentences.
- Idiot Ball: Somehow, Dr. Dráuzio is stupid enough to confuse Conrado for Lapedo. Later, he tells Conrado to say where's the cookie in one of two transparent jars; Dráuzio says he's wrong when he was not, tases him, and says Lapedo has gotten dumber.
