Moopies are a race of creatures that were found on Endion. They were bipedal, furry creatures with heads similar to that of chipmunks. They appeared to have the use of sticks as tools, and were able to create fires.
- Moopies are likely a reference to the Ewoks from the film Star Wars: Episode VI Return of the Jedi, and are one of several references to the movie made during the mission "Unsealing the Past."
- The moopy surrounded by four reptiles in the sewers during "In the Enemy's Shadow" is possibly a reference to Master Splinter from the Teenage Mutant Ninja Turtles franchise.
- In the Galaxy Map Editor, moopies have a weapon named the Moopy Stick. It does 1 damage.
- A group of moopies can be found on a ledge in the center-left corner of Eastwatch.
