Red Coin Field

The Red Coin Field is a secret minicourse in the game Super Mario Sunshine. It is accessed in the northwest of Delfino Plaza via Warp Pipe. It is past the cannon to Pinna Park, on a ledge by some trees growing out of the side of the cliff. It is normally impossible to do this level without the Rocket Nozzle equipped. However, it is possible to reach the pipe with the Hover Nozzle, Turbo Nozzle, or Yoshi.

Once inside the pipe, Mario must collect the eight Red Coins throughout the field. One Red Coin is seen in plain sight and can easily be obtained. Mario can obtain another four coins by defeating the two Pokey Sprouts and two Seedy Pods that pop out of the dense grass. There is a Pianta that has caught on fire and is frantically running around the area; once Mario puts out the flames on him, he is rewarded with a Blue Coin or 1-Up Mushroom, and then he'll be rewarded with a red coin. At the top of the level, Mario can find a red bird. This bird will drop a red coin when doused enough with F.L.U.D.D.. There is a Watermelon Block placed in a square hole near the edge of the field. Ground Pounding it results in discovering a secret alcove in the field where the last red coin resides. Mario will then be able to get to the Shine Sprite.

Trivia

 * It is possible to get to the Red Coin Field with the Hover Nozzle rather than the Rocket Nozzle by jumping on the high trees leading up to its pipe.
 * It is impossible to refill F.L.U.D.D. here, as there is no source of water.
 * The Red Bird found here is dubbed the Sole Red Bird of Happiness by a Pianta ornithologist. It is the only Red Bird in the game.
