Mymoon

The Mymoons are a species of Ape-like creatures that live on the moon Hadea, and a terrestrial relative to the subterranean MoleEster.

Description
The Mymoons, like the MoleEsters, are the most "Earth-like" creatures found on Hadea, having a strong resemblance to a Earth primate such as a Gorilla or Orangutan. They don't have any fur, and instead have purple skin with blue stripes along their arms, and a yellow protrusion on their heads. Unlike true apes though, their eyes are awkwardly positioned upward, making frontal view more challenging.

Interestingly, these territorial creatures are one of very few that use basic tools. The most common one used is a crudely-made club which they use to fight off invaders and predators.
