Chu Jelly

Chu Jelly is a liquid left behind after Link kills a Chu Chu. He can then collect it (in The Legend of Zelda: The Wind Waker it will go in a bag and in The Legend of Zelda: Twilight Princess it must be manually placed in a bottle). In The Legend of Zelda: Twilight Princess, all Chu Jelly is called Chu Jelly so it must be classified by its abilities and the variety of Chu Chu that it came from.

Red Chu Jelly
In The Legend of Zelda: The Wind Waker, 15 samples of Red Chu Jelly can be given to the man at the potion shop on Windfall Island. He will then add chemicals to it to make a Red Potion.

In The Legend of Zelda: Twilight Princess if the Chu Jelly came from a Red Chu Chu, Link can drink it to refill eight hearts.

Green Chu Jelly
In The Legend of Zelda: The Wind Waker, 15 samples can be made into a Green Potion by the man at the potion shop.

Blue Chu Jelly
In The Legend of Zelda: The Wind Waker, 15 samples can be made into a Blue Potion by the man at the potion shop.

In The Legend of Zelda: Twilight Princess, drinking Blue Chu Jelly will ether save Link, kill him or harm him in some other way. Don't even chance it.

Rare Chu Jelly
In The Legend of Zelda: Twilight Princess, this Chu Jelly will have the same effect on Link as Great Fairy's Tears. But Rare Chu Jelly is much harder to find so always use Great Fairy's Tears.
