Stalkin

Stalkin (スタルベビー, Stalbaby) are miniature skeleton enemies found in the Arbiter's Grounds and Cave of Ordeals in Twilight Princess. Similar in appearance to Stalfos, Stalkin emerge from the ground in large groups and attack with small tridents. 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. In the Japanese version, they are known as スタルベビー, or Stalbaby. This is the same as the Japanese name of the Stalchildren, and given their similar behavior they are likely meant to be the same enemy.

Theory
It is also possible for the Stalkin to be the dead remains of the Miniblin as both wield tridents, are relatively small, are easily defeated, make high pitched noises and appear in large hordes.
