Yokul is a lambeosaurus farmer who works on Noxia-4 with Leefer and Frisbee, among others. He was an expert in robots, but became interested in the carnivorous plants that live on the planet, naming them "fearblooms" and studying them. He fell ill from the poisons released into the air by an invasion party of giganotosaurus and went berserk, hitting himself on the head before disappearing into the forest. The fearblooms rescued him, taking him into their tunnels to recover from his sickness.
