Derrick (Experiment 566) is a gray dinosaur-like experiment with a drill-like tail, wearing a construction helmet. He has small ears similar to Jumba's and a large mouth with an overbite jaw posessing two protruding teeth. The brown markings on his body resemble patches of mud.
He is designed to drill potholes in obscure places, most likely to trip people up, make it easier for people to loose possesions or to just simply wreck perfectly good floors, roads, etc.
Unknown, Probably a surface too solid to drill through.
