Cecil is an adult male chameleon. He has green skin with scales all over his body.
He wears a dark orange collared v-necked polo shirt, khaki pants, and name tag presumably as part of his uniform for his job at 8-Twelve. Strangely, he seems to wear the same uniform even outside of his job, such as when he was arrested at David Boreanaz House.
Like real-life chameleons, he has an extremely long tongue with a sticky tip, that can be shot out of his mouth to grab objects from a distance.
He was later seen in Live Fast, Diane Nguyen, where he was arrested, at the scene of David Boreanaz House.
He makes a brief cameo with "my other bike is a tree" guy in Our A-Story is a "D" Story.
