Shadow Sheargrub

"Shadow Sheargrubs" are the name given to the mandiblard-like beings that appear from the shadows and overcome their prey through sheer numbers. Their eyes glow yellow and they can be pretty relentless foes. When defeated, they dissolve on the spot, suggesting that they might even be a natural phenomenon interpreted as living organisms, not unlike the Waterwraith.

Trivia
Shadow Sheargrub's names are partially a throwback to the standard "Heartless" enemies of Kingdom Hearts, the Shadows. Like the Shadows in the game, Shadow Sheargrubs are weak enemies that appear to be similar and attack in large numbers and unexpectedly.
