His first appearance is in Luigi and Guido's Team Relay 2. He then appears in the cut-scene for Rustbucket Grand Prix, where he is seen driving out of the tunnel. He then introduces himself to Lightning McQueen and Sarge, and challenges them to a race in the dark tunnel. Lightning says that he can't race because he has no headlights and that he's scared of crashing, but then Sarge gave him his night vision goggles, so now they could race in the dark tunnel. He races in the race, then in the end-scene, he tells about a story about a monster called the haunted heck. Then Lightning tries to introduce him to Mater, but Mater thought he was the ghostlight, and Gudmund thought Mater was the haunted heck, so they ran away from each other.
