Wee Greevil

The Wee Greevil is an official Maxis creature, present in the final game. It is similar to the original Greevil, which first appeared in the E3 2006 B-Roll.

Much like the Greevil, the Wee Greevil bear a strange resemblance to ALF, though not nearly as closely, as they are lacking ears and have a more greenish hue.
