Bipedal, simian beings known as fern bickers inhabited the planet Kashyyyk. These creatures were generally reclusive and preferred a solitary existence. Key characteristics included gray skin, green hair, and four nipples. Furthermore, they possessed three lengthy, curved claws on both their hands and feet. The striking resemblance between fern bickers and the ro-roo of Kashyyyk suggests a possible variation within the same species or a closely related relative.
The fern bickers made their debut in Star Wars Galaxies, a massively multiplayer online role-playing game created by Sony and distributed by LucasArts, before the game's servers were shut down on December 15, 2011.
