— Description, Sonic the Hedgehog Encyclo-speed-ia

The Bumpalo[1][2][note 1] is an enemy that appears in the Sonic the Hedgehog series. It is a mass-produced, buffalo-based Badnik model created by Dr. Eggman.


Bumpalos are based on buffalos while using the general concept of the RhinoBot. As their name implies, they possess a buffalo-based head with a bumper on their back. They are mostly gray, with their bumper being red, blue, and yellow. They also have cartoonish eyes with black pupils.

In Sonic Mania, and its expansion Sonic Mania Plus, Bumpalos appear exclusively in both Acts of Mirage Saloon Zone. In gameplay, like RhinoBots, they will move forward and backward across the ground they stand, minding their own business, on until they spot the playable character, at which point they will ready themselves and charge at the playable character and skewer them with their horns. Furthermore, any attacks aimed at a Bumpalo's back will get repelled due to its bumper shell, so the player must attack from another angle in order to destroy this Badnik, such as Spin Dashing into the front or back. Mighty, on the other hand, can bypass the Bumper on Bumpalo's back with his Hammer Drop, thereby allowing the player to easily destroy this Badnik. Also, upon its destruction, an Animal will be released.

Powers and abilities

The Bumpalos possess horns quite capable of skewering their opponents. Their backs' bumper shell also make them immune to blunt attacks from certain angels.
