Petrolion

Petrolions were an orange skinned race of humanoid creatures with pointed ears, a long thin tongue and fanged feline-like teeth. Their advanced technology was dependent on petrol. Used as the humans drank water, petrol powered their bikes and their space suits and acted as a fuel for their ships.

Teenage Petrolions were known to visit alien worlds to joy-ride on speed bikes as an act of rebellion. They were stopped from causing havoc on the newly opened M1 motorway on Earth in 1959 by the Doctor, who told them to go home. (DWAM: Madness on the M1!)
