Cloud shaped food
From Starfy Wiki
Cotton candy are movable objects in The Legendary Starfy. They can be found in Skydye Heights where they can be knocked out of cotton candy plants with a Star Spin. Cotton candy can be used to feed a Fluffy Unu, or the one Giant Clam. If Starfy or Starly get stuck in the cotton candy plants, they must rapidly push the left and right buttons on the D-pad to wiggle free. The Toy description for Fluffy Unu suggests that cotton candy is its favorite food.
