Petrolion

Petrolians 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 powerd their bikes, their space suit and as a fuel for their ships.

Teenage Petrolions have been 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 too go home. (DWAM: Madness on the M1!)
