At the Endsville Elementary Carnival, Principal Goodvibes is giving a speech about saving hippos, Mindy doing a school report asks why is he so boring? He gives a few exaggerated examples explaining his non-boring life, making Mindy fall asleep because of his boring talk. Billy and Mandy made a game where they had to hit the target to dunk Grim in a water with eels named Dunk De Reapa. When Irwin is not able to dunk Grim, Tanya comes in and dunks him again and again, which makes Grim angry and he decides to destroy the ball, but the blast from his scythe accidentally hits Principal Goodvibes and the hippo next to him. This turns Principal Goodvibes into a rapper named Goodbling and the hippo into an anthropomorphic beatboxing hippo named H2O. Grim tells Billy and Mandy that the magic can only be reversed when he is challenged by a greater rapper.
The next day, Goodvibes turns the school upside down by cancelling all classes and making classes to make kids learn Hip Hop, wearing a metal was compulsory and everyone challenge each other. Grim goes to complain to Goodbling in retaliation he insults Grim with a Yo Mama joke, making him cry.
In the cafeteria, Irwin starts showing off his Hip Hop dance, where he bumps into H2O and mistakenly calls him a cow. This causes Principal Goodvibes to make fun of his mom, when Tanya comes in and challenges Principal Goodvibes to a Yo Mama insult challenge. Having lost to Tanya, ultimately proving herself to be a much cooler gangsta rapper, Goodvibes returns to his normal self.
