All three of the kids (Lock, Shock and Barrel) are mischievous, rude and rascally children with no respect for their superiors, taking pride by wreaking havoc and chaos whenever they can. Although they take orders from Oogie Boogie, they obey him out of fear, and are generally content to merely perform pranks unless threatened by him. Although Lock is the nominal ringleader, Shock's cunning and bossiness usually put her in charge. When they get in trouble, both of them are happy to throw the hapless Barrel under the bus and blame all their misdeeds on him.
