Poink

Poinks are small floating pig-like creatures in Super Mario Sunshine. They almost always appear in groups. When Mario gets near them, one of the Poinks will attach itself to F.L.U.D.D.'s nozzle. If the player then squirts water, they will start to expand, and if the player releases the R button, the Poink will shoot off in the direction Mario was facing. They are helpful in one of the episodes against Petey Piranha in Bianco Hills. Jumping on a Poink will also cause it to explode.

In the battle with King Boo in Hotel Delfino, one of the ghost's attacks can cause Poinks to appear.

Switching to any nozzle except the Squirt Nozzle prevents Poinks from attaching themselves to F.L.U.D.D..

Trivia

 * Poink's name appears as one of the default high scores in the game Mario Golf: Toadstool Tour.
 * If Mario presses the X button to change from the Squirt Nozzle to the Hover Nozzle (or any other nozzle for that matter) while a Poink is attached to F.L.U.D.D.'s nozzle, the Poink will explode in a small puff of white smoke.
