A Space Corps Law Enforcement Vessel chases Starbug and the crew make a crash landing on a GELF planet. They go in search of a vital ship part and come across a village who have the part but the price is for Lister to marry the chief's daughter. Lister reluctantly does so but on his wedding night, does a runner back to Starbug. The chief takes this as an insult and releases his pet Emohawk, a smaller polymorph (see Polymorph) on them. The Emohawk hides on Starbug and attacks Rimmer and Cat, taking Rimmer's bitterness and the Cat's cool; turning them into Ace Rimmer (see Dimension Jump) and Dwayne Dibbley (see Back to Reality).
