Purple Chu

Chus are enemies from The Legend of Zelda: Twilight Princess. These translucent, amorphous, featureless blobs are found commonly throughout Hyrule, especially in dark areas. Chus can merge with one another to progressively increase in size; when a merged Chu is struck, it will divide into two smaller Chus rather than perish. If Link fails to slay all of these fragment Chus quickly enough, they will rejoin into a larger Chu, forcing Link to start again. When a Chu is slain, a pool of Chu Jelly remains for a few seconds, which can be stored in bottles and used for various purposes. Chus occasionally attack by dropping down from ceilings; when they do so, they emit their trademark squelching noise, allowing Link to dodge them if he is fast enough.

Purple Chus are encountered the most often; their jelly usually recovers or drains a single heart, but will rarely restore all hearts, or even drain all health down to one quarter of a heart.
