Loomish

Loomish were the native inhabitants of Lumana. They had a reputation for conning visitors. They were small, furry, slightly smelly creatures with big, round eyes and large ears. They had incredibly strong family bonds and with their bat-friends in the sky and the Slaken in the caves protecting them, they led an idyllic existence.

When the Tenth Doctor and Martha Jones visited a jungle on Lumana, they were conned by the Loomish into believing they needed protection from the Slaken. While the Doctor and Martha investigated, the Loomish took over the TARDIS. Martha lured them out of the TARDIS by sounding a Loomish trumpet, leading them to believe someone was in trouble.
