Bouncer

The Bouncer is a peculiar species introduced in the Star Wars universe, specifically in the Star Wars Legends. They are spherical beings native to the remote and unknown moon of Ruusan, a location prominently known in 'Jedi vs. Sith' comic series. Bouncers possess the ability to levitate due to the unique stack of gas-filled bladders inside them, which not only allows for movement but also assists them in their survival.

Bouncers communicate through a combination of light patterns and musical tones, emitted from their bioluminescent patches and the whistling noise achieved by expelling air. Though they appear simple, they have an extraordinary connection with The Force. They offer help and guidance to the Jedi, providing insights into their future or the hidden aspects of The Force. Their peaceful and intelligent nature allowed them to establish respect and trust among various Star Wars characters.
