Stalchild

Ocarina of Time
The Stalchildren (スタルベビー, Stalbaby) 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 dirt roads. 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 Stalchildren should have flourished under the rule of Ganondorf. Although, they could just have moved to somewhere more suitable for them. Or due to the speculation of being younger versions of Stalfos, could have just grown up in them.

''Majora's Mask
In Majora's Mask, the Stalchildren are of the Ikana race. In the game, they haunt the Ikana Graveyard and are the fallen soldiers of the Ikana Kingdom. Their general is Captain Keeta, but they'll mistake anybody that wears the Captain's Hat for their fallen leader.

In Relation to Stalfos
Stalchildren and Stalkin are thought by fans to be younger versions of Stalfos in Ocarina of Time.

The only other explanation hinting towards their relation to Stalfos was their ranking in Majora's Mask, in which they are footsoldiers as opposed to the Stalfos-like bodyguards in Ikana Castle. It should be noted that at least one, if not all, Stalchildren in Majora's Mask were adults. There is also the fact that Stalfos don't appear when Link is a kid, and Stalchildren don't appear when he's an Adult.
