Babalu Destructoid Mechanism 1.0.0

Some mini-boss from Super C from the NES.  You can stand on its head, but in order to damage it you have to shoot its bottom.  This is easier said than done, however, due to how its attacks involves shooting bullets in almost every direction, and of course it has hyperarmor.  Let's not forget the Metagross attack on the higher palettes, beyond 1p-4p.
