Stalchild

The Stalchildren, also known as Stalkin, are skeletal nocturnal enemies that rise from the earth immediately after sunset in Ocarina of Time and Majora's Mask, and make appearances in various areas of Four Swords and in dungeons in Twilight Princess. In Ocarina of Time they only appear in pairs, but in later games they show in much larger numbers. They are commonly small, but they can appear in larger varieties.

Despite common perception, these enemies are not skeletal children, but rather simply small, weaker relatives of Stalfos, and are said to be cursed soldiers. They are also not always entirely aggressive, and in Majora's Mask they show the ability to talk.

Captain Keeta from Majora's Mask is the most notable Stalchild to date.

Ocarina of Time
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 dirt roads. Each time Link kills a certain number of Stalchildren, they can grow to a size similar to Captain Keeta from Majora's Mask. Once Link becomes an adult, these creatures mysteriously disappear, and Poes haunt the field in their place.

''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. By wearing the Captain's Hat, the Stalchildren will ask Link whether they should open or guard the grave, mentioning that they already had an order from Captain Keeta to guard it. While this is their most major role in the game, they also have a slight role in the Oceanside Spider House, where each of the Stalchildren in there will reveal the solution to the house's puzzle, ultimately leading to a Piece of Heart.

Four Swords
Stalchilds in Four Swords appear in various locations that the four Links can visit. They are similar in appearance to those in previous games, but they attack differently; throwing their bones at Link in a similar manner to regular Stalfos in A Link to the Past. Their movement is slow and defenses are not particularly strong, but they are able to leap out of the way of Link's attacks. They commonly appear in small groups and are particularly prolific in areas with lava such as Death Mountain.

Twilight Princess
Known as Stalkin in Twilight Princess, they are miniature skeleton enemies similar in appearance to Stalfos found in the Arbiter's Grounds and the Cave of Ordeals. Stalkin emerge from the ground in large groups and attack with small spears. While individually they are weak, they can be quite bothersome in packs. They can be destroyed with almost any weapon, though Link's sword is arguably the most effective for dealing with large groups of these tiny nuisances, especially when the Spin Attack is utilized.
