He later appears in "Free Willzyx", here he gives the boys a lift and helps them take Willzyx to Mexico, which according to him, the boys said they had gotten the killer whale at Pizza Hut. He learns that the whale was actually stolen when Sea Park Announcers named Brian and Mike stop the truck. When Mike is about to tell Kyle that he and Brian have a prank on him, two cops arrive and notice the stolen whale in the truck. When they are about to arrest the Truck Driver and the others, the ALF members arrive to defend the boys. After a brief discussion, they start a shooting and kill Truck Driver along with Mike and the cops.
