Mr. Creeper is the Gym teacher at Strange Hill High. He was grown from a plant called an Australian Creeper because of Mitchell pouring a super growth formula on the plant. He has an Australian accent due to being an Australian Creeper. Because Becky took care of the Australian Creeper he calls Becky "Mum" and listens to what she says (most of the time). He wears a Green Jacket and has hair that looks like a leaf. He enjoys people panting because they breathe out carbon dioxide, which he breathes in.
