Gusty

Gusty's are long, happy ghosts in Super Mario World 2: Yoshi's Island and Yoshi's Island DS. They always travel in huge packs, giving Yoshi 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.
