Cotton Candy is classified as a common food in Adopt Me! which was available during the Monkey Fairground update. It‘s only obtainable through opening a Monkey Box. When eaten, it increases the speed of the player, similar to the Hyperspeed Potion, Candy, and Cookie. The more Cotton Candy the player eats, the faster their speed becomes. Cotton Candy takes a single bite to eat, like a Marshmallow.
It will only be available once the Monkey Fairground event comes around again.
The Cotton Candy features a white paper cone topped with a pink ball of cotton candy.
