Martian Gopher

Martian Gophers are a sapient species of four-armed subterranean rodents from the Martian plains.

Biology
Martian Gophers closely resemble their Earth counterparts, but can be distinguished by having four arms, green fur, and a pair of antennae (the latter traits shared with other Martian species, such as the Marscoon). They have four-fingered hands and three-toed feet. Elderly males can sport white beards.

Culture and society
They're ruled by a king and once plotted to invade the surface world and replace Martians as the dominant species on their planet.
