Yellow ChuChu

Yellow 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
Yellow ChuChus are common enemies and can be easily defeated with a single sword strike. They contain arrows inside them, which are dropped when they are killed.

The Legend of Zelda: The Wind Waker
Yellow ChuChus have electric currents running through them, allowing them to electrocute Link. If attacked with the sword, the electrical current travels along the sword and damages Link instead; therefore, Yellow ChuChus must be dispatched with ranged items such as the Hero's Bow, or stunned with the Boomerang.

Interestingly, considering the conductive property of water, it is surprising that Link is not harmed by being in close proximity while they are in it.

The Legend of Zelda: Phantom Hourglass
Yellow ChuChus in this game are very much like their The Wind Waker counterparts, as they both emit electricity from their bodies and can stun Link on contact. The Boomerang stuns them, and the Bow, Bombs, Bombchus, Grappling Hook, and Hammer can kill them. However, these ChuChus pause in their shocking, making a stunning strike unnecessary to get the one-hit kill in. Another option, is to strike, just before they touch the ground, and if Link is fast enough, they will die.

Should Link touch a ChuChu while it is shocking, he will momentarily be stunned, and his map will become pixelated, making it illegible for a short time.

The Legend of Zelda: Spirit Tracks
Yellow ChuChus are defeated in the same way they are defeated in Phantom Hourglass'. The Whirlwind and the Boomerang stun them and the Whip, Bow and Bombs can kill them.
