Fuzzies (singular: Fuzzy) are cotton-like creatures that float around and debuted in Super Mario World 2: Yoshi's Island. They float slowly in the player's direction en masse. Making contact with a Fuzzie will cause the world around the player to become distorted and rainbow colored for a while. It also causes the player to stumble around uncontrollably.
After a long hiatus, Fuzzies make an appearance in Lets-a-go, Mario. They act just like they did before, however, the effects are different. The player simply stumbles around and has trouble jumping, the player reverts into his/her normal form, the music is distorted, and the screen becomes tinted with a rainbow.
They can also hide in blocks. If the Fuzzie does this, it will pursue a player at very high speeds. The effects are the same.
The game also introduces several other species. Fire Fuzzies burn whoever they touch and make the character dash forward uncontrollably, also tinting the screen orange.
Ice Fuzzies freeze the character into a block of ice, making the player lose control of the character completely. The block will slide forward, and the only way to break free is to hit a surface about 5 blocks lower or mash buttons enough. The screen is tinted baby blue.
Cloud Fuzzies cause the character to flap his or her arms and fly very high. The screen becomes tinted white.
The last type, the Rock Fuzzie, makes the player stumble around disables their ability to jump. The screen becomes sepia-toned.
Fuzzies appear in Super Mario: Elemental Journey as a obstacle in a couple missions in the course Nimbus Station 9. They have the same effects they did in Yoshi's Island.
