Like Likes are an enemy featured in nearly every The Legend of Zelda title and first introduced in The Legend of Zelda. In certain games, they attempt to suck up Link and will eat any unique equipment he is holding at the time, including tunics and shields. If he's fast enough, Link's equipment is returned if it is killed.
The Legend of Zelda
A Link to the Past
Like Likes in Link's Awakening will use all their might to swallow Link. If the Like Like is successful, it was eat Link's Shield, forcing him to buy a new shield as a replacement. The only shield Like Likes cannot eat, is the Mirror Shield.
Ocarina of Time
These obnoxious piles of spam are always hungry. If Link gest too close, they'll reach out towards him (making their front side invulnerable) and suck him in. If they do manage to get Link, they'll steal his shield and any special tunics if he's wearing. If he doesn't kill them fast enough after that, they'll digest them completely. Slash them between their attacks while they're vulnerable as quick as you can.

Oracle of Ages and Oracle of Seasons
The Minish Cap
Like Likes and Rupee Likes can be found in various places and dungeons within Phantom Hourglass. Like Likes will swallow Link and eat his shield, while Rupee Likes will swallow Link and eat his rupees. The only way to prevent this from occurring is to rub the screen on the Nintendo DS rapidly.
Like Likes in The Legend of Zelda: Spirit Tracks act almost identically to those in previous installments. They'll still eat Link's shield, but they are unable to eat the Shield of Antiquity. Sometimes Like Likes will disguise themselves as pots or treasure chests, making a surprise attack on Link very likely.
