Lock, Shock, and Barrel

Lock, Shock, and Barrel are characters from the Kingdom Hearts and Kingdom Hearts II. They are Oogie Boogie's costumed sidekicks. They are a trio of children in Halloween garbs of a devil, witch, and skeleton, respectively. In the first game, they stole an artificial heart from Dr. Finkelstein to give to Oogie. However they were soon caught even though the heart was gone. During their boss fight, Lock used a slingshot, Shock spun like a ballet artist, and Barrel rolled across the floor. The three will appear in Kingdom Hearts 358/2 Days, as they are seen in screenshots playing a trick on Roxas. In Kingdom Hearts II, they became Dr. Finkelstein's pranky assistants during the first visit. When they were out playing, they came across Maleficent and told her of Oogie Boogie's fate. Maleficent revived Oogie and gave them control of the Prison Keeper Heartless as a distraction for Sora and company. In the second visit, they were blamed for stealing Christmas presents from Santa. In the inevitable chase afterwards, the heroes discovered the truth when they told them about Dr. Finkelstein's Experiment.
