Blue Chu Jelly

Blue Chu Jelly is gotten from the very rare Blue ChuChu and is kept in the Spoils Bag. It is used to make Blue Potion, and it s the rarest type of Chu Jelly. In The Legend of Zelda: The Wind Waker, after you kill the Blue ChuChu and take it's spoils, they go directly to your Spoils Bag. It can be converted into a potion by giving it to Doc Bandam on Windfall Island and put in a bottle. You need 15 jellies to make the first Blue Potion, but after that you only need 5 jellies. It heals all magic and hearts. It can also be bought for 60 Rupees.

In The Legend of Zelda: Twilight Princess, once you defeat it, you have a choice of scooping it with an empty bottle, or letting it dry in the ground. If scooped, it can be drank instantly, or saved for later, and restores all hearts. It can also be bought for 100, or 50 Rupees.
