Boss Bass

A Boss Bass is a huge fish found in Super Mario Bros. 3. They swim on the surface of the water trying to lunge out and eat Mario when he gets too close. In some of the levels, platforms rise and fall, making Mario an easy target. Throwing blocks and fireballs can defeat them, but they'll eventually come back.

Boss Bass' are possibly related to the identical-looking Big Bertha.

The Cheep-Chomp from New Super Mario Bros. has similar qualities to the Boss Bass.

Boss Bass' are found in Yoshi's Island DS as well as the first known female Boss Bass: Bessie Bass.

In New Super Mario Bros. Spike Bass took its place.
