Flopsy Fish are Cheep Cheeps that appear in Super Mario World 2: Yoshi's Island and Yoshi's Island DS. Unlike Cheep Cheeps, instead of jumping up in a straight line, Flopsy Fishy jump up and in the water in a curve and can be a bit harder to avoid. Flopsy Fish also have small teeth. In Yoshi's Island DS, Flopsy Fish appear alongside Cheep Cheeps in the same exhibit and same room of the Museum so as a result, if you hit a Cheep Cheep with an Egg, you will also get the Flopsy Fish with it and vice versa.
