Mr. Fowler (voiced by Derek McGrath) - He is the custodian at Ringworm Junior High School. He is small, timid, shy, afraid of Paige, and wears oversized glasses. Always hums the song "4 and 20 Black Birds Baked In a Pie." He grew tired of cleaning up the excess pigeon poop around the school, so he built a giant mechanical owl suit, with which he captures pigeons and plots to put them in a pie to bake them.
