The Mecha Pig[note 1] (メカブタ[1] Mekabuta?) is the Master Robot of Green Hills Zone in Sonic the Hedgehog 2 (8-bit). It is a ball-rolling pig robot built by Dr. Robotnik, and is the fourth boss of the game.


It is a robotic pig modeled after a sumo wrestler, with the ability to curl into a ball (imitating Sonic's Spin Attack) and roll or float from one side of the screen to the other. While rolled up, he is invulnerable to Sonic's attacks.


Boss guide


Sonic fighting Mecha Pig.

The boss battle takes place on a grassy field with a dip in the middle. The Mecha Pig will stand on either side of the dip and perform a sumo stomp and snort steam, after which it will curl into a ball. It will then move across the dip, either rolling down along the grass, or floating straight across the middle, or moving across the top of the screen in an arc. On the other side, it will uncurl to perform another sumo stomp, and this is when Sonic must attack.

After being hit a certain number of times, it will sometimes roll across the screen twice before uncurling.
