Poink

"Poinks get all full of water and then they go BOOM! Hee hee!"

- Pianta

Poinks, also known as Popo, are small floating pig-like creatures found in Super Mario Sunshine. Their name is probably derived from "oink," which is an onomatopoeia for pig sounds, and "pink."

Super Mario Sunshine
Poinks almost always appear in groups. When Mario gets near them, one of the Poinks attaches itself to FLUDD's nozzle. If the player then squirts water, the Poink will start to expand, and if the player releases the button, the Poink will shoot off in the direction Mario was facing. Poinks are helpful in one of the episodes against Petey Piranha in Bianco Hills. Jumping on a Poink also causes it to explode.

In the battle with King Boo in Hotel Delfino, one of the ghost's attacks can cause Poinks to appear. Here, they can be a hindrance, as they temporarily prevent Mario from using FLUDD to defeat other enemies King Boo spawns.

Switching to any nozzle except the Squirt Nozzle prevents Poinks from attaching themselves to FLUDD. Doing so while a Poink is already attached causes the Poink to explode in a small puff of white smoke. If a Poink attaches itself to FLUDD's nozzle while its tank is empty, it will still fill with water and fly off when the button is released.

Mario Golf series
Poink's name appears as one of the default high scores in Mario Golf: Toadstool Tour and Mario Golf: Advance Tour.
