Quadropians are mainly blue skinned aliens that have four legs and are quadrupedal. Their feet and legs have different shades of blue with their feet having a lighter shade. All four of their legs are connected to a drooping abdomen. Their face consists of only a neck, one giant eye on the top with that eye being yellow with a green and black iris, and huge mouth which leaks saliva. All seen quadropians wear high heel shoes due to their feet having the same shape.
