The frog species known as mud frogs originated from a planet situated within the Vagadarr system. When the first mission was undertaken to explore the Vagadarr system, a warrior belonging to the Rockhawkers momentarily mistook the small, green Jedi Grand Master Yoda for a mud frog. Rooper Nitani was able to perceive the distinct calls of mud frogs as he journeyed from the Batuu Jedi temple towards Black Spire Outpost.
