B. Locker

B. Locker is a character in the game Donkey Kong 64. As his name suggests, he blocks the Kongs from reaching new levels. He will let them pass if they have a certain amount of Golden Bananas. B. Locker looks like a big sign post with eyes and three number panels for a mouth. While B. Locker is not really an enemy, he does work for King K. Rool (although unhappily).

Trivia

 * B. Locker's name is obviously a pun of Blocker.
 * There is a glitch where Lanky Kong can pass through B. Locker without having the proper amount of Golden Bananas.
