Stalkoblin

Stal Bokoblins are reanimated Bokoblin skeletons that appear as enemies in The Legend of Zelda: Breath of the Wild.

Their behavior is similar to Stalchildren from Ocarina of Time, as they emerge from the ground at night. Unlike Cursed Bokoblins from Skyward Sword, Stal Bokoblins are completely skeletonized and lack any vestiges of their former life such as clothing or flesh. They also lack the Cursed Bokoblin's ability to Jinx.

Cursed Bokoblins
Given the fact that they are both undead Bokoblins, it is possible that Stal Bokoblins are actually Cursed Bokoblins that have been undead long enough for their flesh and clothing to have decayed, transforming them into Stal Bokoblins. Presumably, they may have lost their ability to curse during this process. Of course, it is possible that they may simply be unrelated species of undead Bokoblin.
