Spray Fish



Spray Fish are blue fish in Super Mario World 2: Yoshi's Island and Yoshi's Island DS. They appear in several fortresses and castles and shoot out a diagonal jet of water. It's almost like a wall and impossible to go through. Wait for them to submerge or shoot an egg at their head. They themselves can hurt Yoshi, but the water pushes Yoshi back.

It's possible they're related to Cheep-Cheeps and the Blue Blurps from Yoshi's Story. Hot Lips (from the original Super Mario World 2) may also be a lava version of the Spray Fish (as he has an identical, though much more dangerous, attacking pattern).
