From the Super Mario Wiki
A Wild Ptooie Piranha, also known as Ptooie Piranha Plants, is a Wild Piranha that shoots Needlenoses at Yoshi. It has a green color, as opposed to the regular red of any Piranha Plant. It also takes three hits to defeat. After the first hit, it turns yellow, then red before finally being defeated with the next strike. Chomp Rocks and Eggs thrown by Baby Donkey Kong can defeat it instantly. Wild Ptooie Piranhas are only known to appear in Super Mario World 2: Yoshi's Island, Yoshi Touch & Go (where they spat Spiny Eggs, which could be destroyed with an egg or stylus tap, rather than Needlenoses), Yoshi's Island DS, and Yoshi's Woolly World.
Wild Ptooie Piranhas reappear in Yoshi's Woolly World, acting fairly similarly to previous games. However this time, when they are hit with a yarn ball they do not change to a different colour.
Their name seems to suggest that they're related to Ptooies (another type of Piranha Plant), but it is unknown whether they are or not.
