He was the leader of the triceratops colony on Aggadon and was a nervous creature who was terrified when a group of furry monsters appeared on the planet without warning and terrorized his colony. Chas is also an inventor who took his mind off the creatures by building remote-controlled dinner-bots. He showed Gipsy and Arx a meteorite and was startled when the corythosaurus split it open with slodge, but there was nothing inside. A group of monsters appeared and the trio fled for their lives, eventually reuniting with Teggs and Iggy, who had found tracks of a Dungdozer Prime and some strange footprints. When Teggs and Iggy crash-landed back at the triceratops camp, they offered to take the entire colony onto the Sauropod.
