Spiny ChuChu

Spiny ChuChus are a type of silver ChuChus in the Zelda series. They have only appeared in The Legend of Zelda: The Minish Cap where they are the most difficult to defeat type of regular ChuChus iin the game.

Behavior
Spiny ChuChus are able to create spikes from their bodies to protect themselves. These spikes are generally used only when Link gets to close to the Spiny ChuChu and allow them to resist almost all attacks in the game. The only way to defeat a Spiny ChuChu while its spikes are out is by using a Bomb. Link can also kill him with regular means if he is quick enough and hit it before it has the chance to use its spikes. They appear at Mt. Crenel, and also act as the mini-bosses of the Cave of Flames.
