He was once the principal of the school Mario and Luigi attended. Unfortunately, Mario took drugs, causing him to go insane. He trashed an office, spooked his other classmates on a pool, and danced on the school's rooftop, causing an angry Fattman to try and calm him down. In the end, Mario grew so insane that he burned the school. Furious at the destruction of his school, Fattman cursed Mario, and after expelling him and Luigi, hoped Mario would burn in Hell for his actions.
