It resembles a gray and mint green Masher from Sonic the Hedgehog. Unlike Masher, which simply moves up and down, BFish attacks Sonic in an arc-like motion. To destroy the badnik, the player would have had to simply roll or jump into it like its Sonic 1 counterpart. It originally was set to appear in Hidden Palace Zone.
