Sheargrub

Sheargrubs are boring and stupid creatures that frequently get their heads stuck in walls which allows terrorists researchers like the in famous Captain Olimar to punch them repeatedly, killing them. The males are purple and have teeth, the females are grey and have no teeth and no method to break down food and so will eventually die of starvation. Sheargrubs are actually illegal immigrants from the planet N080DY.C4R35 but they are so small and insignificant that nobody cares.
