Pikit

The Pickit Plant hops around the screen, and when Link gets close it extends its tongue to steal from him. Pickit Plants can be found all over the Dark World and should be kept at a distance if Link is saving up rupees. They will also try to take shields. However, if Link destroys the Pickit Plant, he may retrieve his stolen items.

Trivia
The Pickit Plant Japanese name is "Like Like", a monster with which it shares the propensity of stealing shields.
