Mike Young Productions ProfileEdit
The principal of Middleborough Upper School, Ms. Monserrata, is Latina-American. An authoritarian and strict disciplinarian, she rules the school with an iron fist, despite the fact that she's even shorter than Creepie. It's hard for Creepie to conform to the principal's strict rules of behavior, but it gets worse because every time Creepie gets in trouble, Ms. Monserrata wants to set up a meeting with her parents - A meeting Creepie makes sure will never happen.
