Bu-bu (ブーブー Būbū?)[1] is an enemy that appears in Sonic Advance 3. It is a mass-produced, pig-based Badnik model created by Dr. Eggman.


The Bu-bus are based on piggy banks.


The Bu-bus only appear in Toy Kingdom. In gameplay, they simply move back and forth without attempting to attack the player. However, should the player take damage and drop their Rings near a Bu-bu, all of said Rings will be sucked into the Bu-bu. If the player does not destroy the Bu-bu fast enough, then the Rings its sucks in become impossible to regain.


  • Bu-bus name is Japanese for "oink".
