The Sky Moon (スカイムーン? lit. Sky Moon) is a type of Badnik created by Dr. Eggman and Dr. Eggman Nega. They serve as enemies in the Sky Babylon stage of Sonic Rush Adventure, levitating in the stage and are easily destroyed by a Spin Jump/Axel Jump or a Sonic Boost/Burst Dash. Red versions, which sometimes fire lasers at the player, are also encountered in Act 2 of Sky Babylon, but otherwise act the same. Sky Moons are also encountered in Hidden Island 5 and Hidden Island 16.
