Uutsubo (ウーツボ Ūtsubo?)[1] is an enemy that appears in Sonic Advance 3. It is a mass-produced, eel-like Badnik model created by Dr. Eggman.


The Uutsubos resemble golden eels.


The Uutsubos only appear in Ocean Base. In gameplay, the Uutsubos lack any usage of a conventional weapon to attack. Instead, they reside in holes, vertical to a wall, and will pop their head out to attack, which can take the player by surprise. The player must attack their head in order to destroy them.
