Mega Fuzzies are larger Fuzzies found in the New Super Mario Bros. series. They have the same moves as a Fuzzy and just like them, follow set tracks however their larger size makes them harder to avoid. Despite their large size, they can be destroyed in the same way as a standard Fuzzy. Fireballs and Shells can instantly destroy one while iceballs can freeze a Mega Fuzzy to be used as platforms for reaching high ledges and getting Star Coins.
Mega Fuzzies later appear in New Super Mario Bros. 2. In this game, they are commonly found in caverns such as World 4-C. The use of the Super Leaf and the Gold Flower can also be used to defeat them in this game.
Mega Fuzzies also appear in New Super Mario Bros. U, New Super Luigi U, and New Super Mario Bros. U Deluxe behaving as they did before. In this game, they are commonly found in various levels of Rock-Candy Mines, Meringue Clouds, and Superstar Road alongside the smaller Fuzzys. In this game, the Mega Fuzzy can also stay in one place and float in the air as an idle obstacle.
