Stalchild

Stalchildren are presumably younger Stalfos and they appear in most of the 3D console games. They are not much a threat alone, but can be a nuisance to Link when they attack in groups (which they usually do).

Ocarina of Time and Majora's Mask

Stalchildren haunt Hyrule Field and Ikana Graveyard in Ocarina of Time and Majora's Mask respectively and they attack by swinging small punches at Link. A bigger one will appear after a while. They, especially the giant ones, will reward Link with Rupees and are a good source of them.

Twilight Princess

In Twilight Princess they are called Stalkin.
Enemy: Stalkin
Attacks: Spear (quarter-heart)
Found: Arbiter’s Grounds; Hyrule Castle
Description: Stalchildren generally attack in groups, swarming Link and thrusting their spears. Singularly, stalchildren can be defeated with several swipes of the sword. In large numbers, they are easily dispatched with a few quick spin attacks.
