Fuzzy

A Fuzzy is a floating, furry, spore-like creature found in Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3 and is the sole member of this enemy group. When Yoshi makes contact or eats a Fuzzy, he gets dizzy, and the whole level is affected. While in this state, your Yoshi may have a hard time walking and aiming eggs, and it will be especially difficult to understand the map well, as the whole background will flash rainbow colors, move and twist around. Fuzzies always appear in large groups and hover all over the field. Yoshi can avoid the dizzy effects by crouching.

They have their own level named after them, "Touch Fuzzy, Get Dizzy", which is also the first level to feature them. Fuzzies also appear in "GO! GO! MARIO!!", "Beware the Spinning Logs", and "Fight Toadies with Toadies" (the latter being in the remake). Their effects there are more hazardous, due to the abundance of abysses in those levels.
