Lock, Shock, and Barrel are Oogie Boogie 's former henchmen and the (former) secondary antagonists of Tim Burton's The Nightmare Before Christmas. They are a trio of trick-or-treaters from Halloween Town who are very mischievous and easily influenced.
The Pumpkin King Edit
Lock , Shock , and Barrel's first appearance is when they report to Oogie about Halloween Town prior to his invitation. They tell him about how scary Jack was; Their next appearance is when they try to trap Jack in the mayor 's house. Later in the lab, Dr. Finkelstein realize that they have kidnapped Sally . They appear later when they stuck the corpse kid in the giant pumpkin. They then run off escaping Jack . Later the big witch tells Jack she saw that they were heading out to Spiral Hill. Jack brithly catch up to them in the Graveyard were they were vandalising a light pole but they escape. With the help of the bat lanter, he tracks them down and demands to know why they're runing the town. Barrel accidentally said their boss told them to, which angered Shock, as it was supposed to be a secret. They then distracted Jack by giving him a second mini game in a present and ran while he was distracted. They sealed the exit behind them with a heavy tombstone trapping Jack and the mayor. They also help the bugs kidnap Igor and put one of the vampire brothers in some sort of trance (with the help of one of the boss bugs) to stop him from delivering the bat boomerang upgrade to Jack .
The Nightmare Before ChristmasEdit
They are also not completely loyal to Oogie as they are simply making mischief to stay on his good side and would prefer to do harmless fun which they seem to enjoy more. Instructing them to "leave that no-account Oogie Boogie OUT of this!", Jack sends Lock, Shock, and Barrel to "Kidnap the Sandy Claws" (the Halloween Town residents' mistaken name for Santa Claus). At first, they accidentally capture the Easter Bunny, whereupon Jack apologizes to it and orders the trio to take the bunny home. They then capture their true quarry after a good many days, shouting "trick or treat!" before shoving him into their Leather Sack . The trio take Santa Claus to visit Jack and then to Oogie's Lair, because, according to Lock, "there isn't anywhere in the whole world more comfortable than that!" After being deposited there, Santa is taunted and theatened by Oogie. Shortly after Jack defeats Oogie and rescues Santa Claus, a hatch above opens and Lock , Shock , and Barrel appear, having led the Mayor to Oogie's Lair . In the deleted scenes, a sequence shows Lock, Shock, and Barrel spectating as Oogie tortures and teases Santa Claus and Sally the rag doll. They watch from their moving cage that hangs on a rope; Jack slips down and scares them away before entering Oogie's Lair . The only time their names are mentioned in the movie is the scene they say them to the Mayor , stating that Jack had sent for them by name.
Oogie's Revenge Edit
Jack, once again tired of the same old tricks for Halloween, leaves town in search of new ideas. In his absence, Lock, Shock, and Barrel resurrect their master Oogie Boogie, allowing him to inflict terror over Halloween Town once again. Oogie kidnaps the Holiday Leaders of Valentine's Day, Easter, Thanksgiving, St. Patrick's Day, and Independence Day, and imprisons them in his underground lair. Lock, Shock, and Barrel are entrusted with hiding each of the seven Holiday Doors in each area of the town where they wouldn't be discovered. They also raise armies of ghosts and skeletons to counteract Jack's inevitable attempt to fight upon his return.
Shortly after Jack comes back, he encounters the trio in the Graveyard, and they refuse to reverse the damage. Lock engages him in battle, and retreats after his skeletons are defeated. When Jack goes to free Sally, Lock fights him once more, this time entering the fray himself, but loses again. Soon after, when Jack attempts to free Dr. Finkelstein, Shock confronts him with an army of ghosts, but retreats upon losing. She confronts him again at the Doctor's Lab, using giant metal balls to deter Jack from climbing the spiral ramp to the lab. Like Lock, Jack warns her to stop helping Oogie, and like Lock, she agrees, but crosses her fingers behind her back. They're next seen at the Pumpkin Patch, where Barrel forces Jack to navigate a maze that he created to reach him in the Big Pumpkin Head. Upon succeeding, Jack fights Barrel and the skeletons under his control, taking from him the Thanksgiving Door and the key to the Residential Area.
When Jack reaches the Mayor's house, he finds Lock, Shock, and Barrel on the roof, where they face off one last time. Upon their defeat, Jack claims the Independence Day door, but the trio use a trick switch to open a void beneath him, dropping him into Oogie's underground lair and remarking, "Looks like he really fell for that one." They are not seen or mentioned for the remainder of the game after this. it is unknown what became of them afterwards.
In Kingdom Hearts, they steal an artificial heart from Dr. Finkelstein to give to Oogie. However, they are soon captured, without the heart. After their battle, they reluctantly reveal tips on how to defeat Oogie. It is assumed they leave the mansion afterwards, since they are seen in Kingdom Hearts II.
The mischievous trio appears again in Kingdom Hearts 358/2 Days, repeatedly playing a trick on Roxas. Usually, when Roxas is about to leave Halloween Town, the three will sneak up behind him and yell "Trick or Treat!" When Roxas turns around, they throw a pumpkin bomb at him, which explodes in his face, then run off laughing. After the first prank, Barrel finds the "head" of the Leechgrave Heartless and keeps it as a pet. Eventually fed up with this, Roxas dodges one of the pumpkin bombs, and engages in a fight with the trio. The trio then reveal to Roxas that they fought him so that he won't find out their secret (Barrel's pet Heartless). Unfortunately, the Leechrave got bigger and violent, and the children were apparently trapped in their own hideout for weeks trying to get away from it. They later managed to escape when Roxas came to exterminate the Leechgrave, and play one more prank on Roxas before he leaves and are not seen again after this.
In Kingdom Hearts II, it is revealed that they became Dr. Finkelstein's assistants. When they go out to play, they come across Maleficent and tell her of Oogie Boogie's fate. Maleficent revives Oogie and gives them control of the Prison Keeper Heartless as a distraction for Sora and company.
