Prison Keeper

The Prison Keeper is a Heartless boss in Kingdom Hearts II. It appears in Halloween Town on the first visit.

After she resurrected Oogie Boogie, Maleficent left Lock, Shock and Barrel behind to deal with Sora and Jack. She summons a Heartless called the Prison Keeper. The Heartless attacks depending on which of the trio it has swallowed. The three sit in the cage at its base. After a while it would swallow a child. Its attacks depended on the child:
 * Shock: The Prison Keeper will spin its arms around, rising up and then falling down while spinning around the arena. Its hands glow blue.
 * Lock: It will shoot large fireballs out of its mouth from a distance. Its eyes glow red.
