Gusty

Gusties are long, happy ghosts in Super Mario World 2: Yoshi's Island, Yoshi Touch and Go and Yoshi's Island DS. They always travel in huge packs, giving Yoshis extra eggs, and making stepping stones to reach high areas. Unfortunately, they fly all over the screen, making quick movements hard.

Try not to bump into one, or else catching Baby Mario could be a pain. They appear in levels where the terrain is bumpy and uneven.
