Celestial Barnacles:
Like Barnacles attach to sea ships, Celestial Barnacles attach to space faring ships. They eat the space dust these ships often drift through while exploring the galaxy. These guys are otherwise relatively harmless, and can become great and friendly companions. They come in many shapes, sizes, and forms, as different planets contain different species as per the environment.
WARNING: they can be temperamental and troublemakers if not feed often enough and properly. Feed them at least one 11 oz can of space fluff or a bottle of condensed space dust.
