Blue ChuChu

Blue ChuChus are recurring enemies in the Legend of Zelda series. Gelatinous blobs, they are a variety of ChuChu.

The Legend of Zelda: Majora's Mask
Only one Blue ChuChu can be found in the game: inside a chamber in the Great Bay Temple. Unlike the other ChuChus found in Majora's Mask, the Blue ChuChu does not have an item in it. However, if it is hit with an Ice Arrow, it becomes a climbable block of ice, allowing Link to reach a high ledge.

The Legend of Zelda: The Wind Waker
Blue ChuChus are the rarest ChuChus in the game, with only 23 of them scattered throughout the Great Sea. Unlike the other varieties, they are never seen in dungeons, only appearing on choice islands either alone or in groups of 2-3. Also, they don't chase Link around; instead just moving around a set area. However, they are very like the Yellow ChuChu in the way they emit electricity and must either be stunned with the Boomerang or wait for the current to die down. Upon initial defeat, they will yield Blue Chu Jelly, which can be made into a Blue Potion when brought to Doc Bandam. After later victories, Link will only receive yellow Rupees.

The Legend of Zelda: The Minish Cap
Blue ChuChus appear in the Palace of Winds. They, like previous incarnations, have electricity pulsing through their bodies. The electric current is constant, starting briefly after they become solid, forcing Link to either use ranged weapons in order to stun/kill them or strike them quickly after they solidify.

The Legend of Zelda: Phantom Hourglass
Blue ChuChus are much more rare than Yellow ChuChus, as they only appear on Goron Island, the Temple of Ice, and certain ships. They are, however, only slightly more dangerous. Though both types of ChuChus emit electricity, Blue ChuChus never stop, and must be stunned before the one-hit kill can be delivered. However, Bombs and arrows can be used for instant kills. If Link touches a Blue ChuChu he will be shocked and the map screen will momentarily become fuzzy and hard to make out.

The Legend of Zelda: Spirit Tracks
Blue ChuChus are electrified ChuChus. They surprise Link by popping out of the ground when he nears. They are impervious to almost all of Link's normal attacks. They can only be damaged by Light Arrows, the Phantom's sword, the Lokomo Sword, the helmets of Helmet ChuChus, and swords pulled from statues with the Whip. When Link touches them he is electrocuted, causing his map to blur.
