Chu Jelly Juice Shop

The Chu Jelly Juice Shop is a location in The Wind Waker, situated next to the mansion of Windfall Island. It specializes on using Chu Jelly to make potions and it is run by the eccentric Doc Bandam. At first, the shop only offers the Red Potion. When Link gives him 15 Green and Blue Chu Jelly, Doc Bandam will be able to make Green and Blue Potion, respectively. Every time Link gives him 5 more Chu Jelly, the potion-maker will give the young hero a free sample of the new potion, either a red, green, or blue potion, depending on what type of jelly Link gives him. Even if he has already made that type of potion, he will still give Link a free sample.

Trivia

 * Through hacking, one can read the signs in the back of the shop, which all read "No Entry. The forest paths are closed until suspension bridge repairs are complete"
