Three children approach you.. the three had outfits resembling a demon, a skeleton, and a witch..

Lock, Shock, and Barrel: >:) TRICK OR TREAT!

They all introduced themselves one by one.. The demon-themed one speaking first..

Lock: I'm Lock.

The witch-themed one spoke next..

Shock: I'm Shock..

The short, skeleton-themed one spoke last..

Barrel: And I'm Barrel!

They spoke in unison again..

Lock, Shock, and Barrel: AND WE'RE THE TRICK OR TREAT TRIO! Oogie Boogie's little henchman and we take our jobs with pride!
