The Red Coin Fish is the eighth episode of Noki Bay in Super Mario Sunshine. The episode's objective is to enter the underwater cavern once more and collect the Red Coins.

Upon entering the level, the Noki grandson will provide Mario with the helmet, then tell him to talk to his grandfather at the top of the mountain. The elder will say that he and the other Nokis want to reward Mario for helping to clean their bay. Diving into the waterfall once again will bring Mario to the underwater cavern.

The Coin Fish is composed of all eight of the Red Coins and several Yellow Coins. The player has to collect all eight Red Coins while collecting the Yellow Coins to avoid running out of air. Occasionally, the Coin Fish will split apart, sending its remaining coins in several directions before coming back together a few seconds later. Once all the Red Coins are collected, the Shine Sprite will appear at the bottom of the cavern.

Trivia

 * In this episode, if the player collects 100 coins in Noki Bay, the Shine Sprite will spawn on the curvature of the orange shell, rather than on top like the other Noki Bay episodes.
