Bigbom

Bigbom is a badnik in Sonic the Hedgehog CD's Metallic Madness. It isn't listed in any instruction manual, however it is referred to as "bigbom" in the game's source code. It is just a giant version of Sonic the Hedgehog's Bomb, with the projectiles he explodes into also giant. They are placed on paths near tight corners where you need to go to advance the level, making them impossible to avoid and escape from their projectiles difficult.
