Cloud Drop

Cloud Drops are ghosts that fly in a short line vertically or horizontally in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3, Yoshi Touch and Go and Yoshi's Island DS''. They appear in packs and in areas where Yoshi can turn into a helicopter. They create air traffic and are difficult to maneuver around, but they can be hit on the head, causing them to fly down like a hit plane.

They are possibly related to Gustys and Lava Drops.
