Stalchild

The Stalchildren can be seen roaming the fields of Hyrule at night in Ocarina of Time. They pop out of the ground, walk slowly toward Link, and attempt to slash him with their claws. They are quite easy to kill, and if Link destroys enough of them in one night, a larger one will pop out; if it is defeated, it will give a larger rupee reward than the others. If two of these larger ones are defeated before dawn, an even larger one will appear. To prevent their appearance altogether, put on the Bunny Hood before nightfall or simply stay on the path. Once Link becomes an adult, these creatures mysteriously disappear. It is theorized that something could have wiped them out during the seven years after Ganondorf took over Hyrule. The logic of this happening is often argued, as it is widely considered that the Stalchilds should have flourished under the rule of Ganondorf. In Majora's Mask, the Stalchildren are of the Ikana race. In the game, they haunt the Ikana Graveyard and are the common soldiers in the Ikana army. Their general is Captain Keeta, but they'll mistake anybody that wears the Captain's Hat for their fallen leader.

Stalchildren and Stalkin are also thought to be younger versions of Stalfos in Ocarina of Time. (though they are only lower-ranking soldiers in Majora's Mask).
