Blue ChuChus

Chuchus are blob-like enemies that have been used through-out the series. These enemies drop items, such as jellies (in TWW) and other items (in MM). Blue Chuchus are unique.

In Majora's Mask, they hold nothing inside them, and only used to freeze. They are found in Greatbay Temple.

In The Wind Waker, they are electrified and drop Blue Chu Jelly. There is only one Blue Chuchu per island in this game, and they only drop their jelly once. Give the Jelly to the Jelly Guy and get a Blue Potion.

In The Minish Cap, the Blue Chuchu is a miniboss in the Temple of Droplets, only because it is giant compared to Link's Minish point of view.

In Twilight Princess, it can be killed to obtain Blue Chu Jelly, which refills all of your hearts. They are found all over in dungeons and grottos.
