Coin Fish

"Master Mario! Our people have all come back at last! To show our thanks, we've prepared a fine treasure for you. It lies on the ocean's floor, so please go there and claim it."

- Noki elder

Coin Fish is a fish whose body is made out of 31 Yellow Coins and eight Red Coins. Mario must propel himself through the water with F.L.U.D.D. to collect the eight Red Coins from the body of the fish during the events of "The Red Coin Fish" in Noki Bay – Super Mario Sunshine's eighth level. This is the only level in Noki Bay in which the Coin Fish makes an appearance. Even though its body is composed of coins (which are inanimate objects), the fish still appears to be alive. Usually, the Coin Fish will just swim around in the water, but occasionally, it will completely separate into the multiple individual coins that comprise it, which will then float around randomly in the water. It will then reform back into a fish shape after a few seconds. When Mario successfully collects all eight Red Coins from the body of the fish without running out of air, a Shine Sprite will appear at the bottom of the bay.
