Discipline Crabs are small, moral crustaceans that need to stick close to the water, and thus are found in cellars, fallout shelters, and other subterranean lairs near the coast. These brooding curmudgeons are deeply offended by the slightest intrusion; if cornered, they employ their razor-edged pincers with righteous efficiency. Discipline crabs live in nests made of random bits of ocean debris, and are fond of jewelry such as gold crowns.

Discipline Beach is the primary spawning ground of these giant crabs, which unfortunately frequently venture inland towards Grubbo-by-the-Sea.
