Petrolion

Petrolians are an orange skinned race of humanoid creatures with pointed ears and a long thin tongue, with fanged feline-like teeth. Their advanced technology is dependent on the fossil fuel petrol. Used as the humans drink water, petrol powers their bikes, their space suit, and is also used 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.
