Orange Juice Generator

Orange Juice Generators, also called Juice Generators or OJ Generators, are pulsating force fields comprised of yellow goop that appear in Super Mario Sunshine. They block access to items, prevent certain passageways from being entered, and damage Mario on contact. These shields can be dissolved only by juice spat from a Yoshi — unlike most types of goop, they are unaffected when sprayed with water. They have a zigzag shape (also appearing to have an "M" similar to M Graffiti) and undulate when Mario approaches them. There are only six Orange Juice Generators in the game.

Orange Juice Generators appear in the following locations:
 * 1) Blocking the Warp Pipe leading to the Lily Pad Ride on a small island off the east coast of Delfino Plaza. This island can only be reached by riding a series of boats starting from either the mainland or another island located off of the south coast.
 * 2) On the back of the police station's tower in Delfino Plaza, covering a small hole containing a Blue Coin.
 * 3) On a tall building near the cannon leading to Pinna Park, covering a small hole with a Blue Coin in it.
 * 4) Blocking the entrance to a cage containing a Shine Sprite in Episode 8 of Ricco Harbor (Yoshi's Fruit Adventure).
 * 5) Covering a Dune Bud to the left of the Sand Cabana in Gelato Beach.
 * 6) On a flat green mushroom under Pianta Village in Episode 5 (Secret of the Village Underside), covering the entrance to a secret level.
