Trouter

Trouter is a fish-like enemy appearing in Super Mario Bros. 2 that jumps up and down throughout the water, attempting to attack the player. These enemies, however, can be used to cross throughout areas in the game. The player also loses a life when having one heart left and is touched by Trouter or when falling down the waterfall on Trouter. They can first be found in World 1. These enemies can also be easily used when using a Stop Watch.
