The Cheddar

The Cheddar is the main antagonist of the episode Teenage Mutant Ninja Turnips. He was first seen on Channel 6 News slicing an apple in half and destroying the camera. Donatello, Michelangelo, Raphael, and Leonardo came to the surface to rescue the city from The Cheddar. After slicing broccoli, he and his henchmen, Peapod and Stalksteady began battling the Teenage Mutant Ninja Turnips. Donatello was able to slice both of them, completely unaware of doing so. When things started to look hopeless for Cheddar, he was able to pull out another sword and being fighting the turnips back. However, Donatello remembered Orange's advice about imagining their opponents in their underpants. He was able to remove Cheddar's cape, revealing his unicorn-themed boxers. This distracted and humiliated Cheddar, distracting him from the fact that he was about to be grated by Dane Boedigheimer and put into a pizza.
