Windsor Gorilla is a highly intelligent Western lowland gorilla, who serves as the anti-bully at the school and often gives confusing wisdom to people. He speaks in a soft-spoken and nearly monotonous manner, often stringing together technical words as a matter of his normal speech. When he talks, only the side of his mouth closest to the camera moves and the rest of his mouth remains closed. He is usually seen with Slips and is generally shown to be the leader of the two. Windsor tends to relate with Adam's troubles better than the rest of the school, having a good grasp of both human and animal worlds, although he occasionally gives in to his animal instincts as well. Windsor has an older brother in high school who plays for his school's football team.
