Wild Ptooie Piranha

A Wild Ptooie Piranha, also known as Wild Ptooie Piranha Plant , Ptooie Piranha Plant , or Green Piranha Plant , is a Piranha Plant that shoots spiky, often cactus-like enemies at Yoshi. It has a green color, as opposed to the regular red of any Piranha Plant. They are usually depicted with a tongue of the same color as its head.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
In Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3, Wild Ptooie Piranhas spit three consecutive yellow Needlenoses in the direction of Yoshi, then rest for a brief moment before repeating the attack. The Needlenoses are shot on arcs of varying lengths; the first two Needlenoses are always shot at a close distance while the third one is sent further. If Yoshi comes into contact with a Wild Ptooie Piranha, it will act like a regular Wild Piranha, grabbing him in its mouth for a while and causing him to lose Baby Mario.

Wild Ptooie Piranhas can be attacked by throwing objects at them, such as eggs or enemies, and require three such attacks to defeat. They turn yellow with the first hit, then red with the second. They can also be defeated instantly by rolling a Chomp Rock onto them.

As shown by prototype builds of the game, they were originally intended to spit Spiked Fun Guys.

Yoshi Touch & Go
In Yoshi Touch & Go, Wild Ptooie Piranhas spit Spiny Eggs, which can be destroyed with an egg or a tap on the touchscreen.

Yoshi's Island DS
Wild Ptooie Piranhas return in Yoshi's Island DS, acting the same as in the predecessor. Here, they can also be defeated instantly with an egg thrown by Baby DK.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Wild Ptooie Piranhas reappear in Yoshi's Woolly World and Poochy & Yoshi's Woolly World, acting fairly similarly to previous games. Unlike previously, however, when they are hit with a yarn ball, they do not change to a different color. Their projectiles (Pokey Poms and Shy Guys) also roll along the ground.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, Wild Ptooie Piranhas are mentioned briefly by Viridi during Palutena's Guidance dialogue for Piranha Plant. Piranha Plant’s yellow costume also resembles a yellow Wild Ptooie Piranha.

 * Official Nintendo Player's Guide: Blow them out of the ground with three eggs. Replenish your supply by swallowing the seeds they spit out.

Yoshi Touch & Go
(When you get close to it, it spits a spiky ball at Yoshi. Each time you hit it with an egg, its color changes from green to yellow to red, and you can defeat it by hitting it three times. Touch the flying spiky ball or hit it with an egg to knock it away.)
 * Shogakukan guide: 近づくとヨッシーめがけてトゲ球を吐いてくる. タマゴを当てるたびに緑→黄色→赤と色が変わり、3発当てると倒せる. 飛んできたトゲ球は、タッチするかタマゴで擊ち落とそう.
