Red Coin Field
The Red Coin Field, also called Pipe Down #1, is a secret minicourse in the game Super Mario Sunshine. It is accessed in the northwest of Delfino Plaza via Warp Pipe. Although it is possible to reach the pipe with the Hover Nozzle, Turbo Nozzle, or Yoshi by jumping on the high trees leading up to the pipe, it is easiest to get there with the Rocket Nozzle.
Mario will then be able to get to the Shine Sprite.
