The leader of the kids
Lock is one of the three kids trick-or-treating in Halloween town in the movie The Nightmare Before Christmas but also one of Oogie Boogie’s sidekicks whom they serve more out of fear than real conviction. Lock is the leader of the little gang and although he is clearly not the smartest, the others always end up following his orders. It is the three of them who kidnap Santa Claus on Oogie Boogie’s orders after they make a mistake and kidnap the Easter Bunny by mistake. It is Jack Skellington who will bring the rabbit back home and take Santa’s place until it is found.
