The first miniboss in Brotherhood.
The fish is below a bridge you are walking on, therfore can not be harmed. The fish continually rams the wall, causing rocks to fall. Then, it extends what looks like a razor sharp fin from its back, the trys to slice you with it. Finally, it sucks in all the water and releases it in a "water meteor storm." It then jumps onto the deck. This is your chance to hurt it. Since the fish has lots of weaknesses and low HP, it should turn into Sushi the first time. If you don't kill it in that time, it repeats the pattern. It has 400 HP.
