Yellow Chuchu

Yellow ChuChus appear in most Zelda games, and are basically the same in each, except for a few exceptions.

Majora's Mask

Majora's Mask is the only game that features a Yellow ChuChu that does not have electrical powers. They are quite common, easily killed, and hold arrows inside their bodies that can be collected when they are defeated.

The Wind Waker

The Wind Waker took Majora's Mask's Yellow Chus and put electrical currents in them, making them less common and more dangerous. Link must first hit the Chu with his boomerang or the Hero's Bow to stun or defeat the Chu safetly. If Link tries to attack a Yellow Chu directly, it will shock him. Even if a Yellow ChuChu is inside water along with Link, despite water's electrical conduction, he will not be shocked.

Phantom Hourglass

Phantom Hourglass kept with The Wind Waker's version of the Yellow ChuChus, staying with their electricity. In this game, though, their electric does not last forever. Link has the choice of either stunning the Chu then attacking or waiting for the electricity to stop, making it possible to attack without being hurt. If Link gets shocked in this game, he will be stunned and the map on the top screen will become pixalated and slowly become normal again.

Spirit Tracks

Yellow Chus are basically the same in this game as in Phantom Hourglass, along with the Whip and Whirlwind being able to stun them.

Skyward Sword

Yellow Chus appear again in Skyward Sword, with basically the same properties as the other games and are defeated like regular Chus.
