King Kut Out

King Kut Out, also referred to as Cardboard K. Rool , is the second-to-last boss in Donkey Kong 64 and the boss of the area Creepy Castle. He is a giant cardboard cut-out of King K. Rool.

After the Kongs managed to open the boss door in Creepy Castle, they ventured inside. Unfortunately for the Kritters on the other side of the door, there was no one to guard the Boss Key kept by the two of them. At the last minute, the Kritters managed to build a poorly constructed cardboard cut-out of K. Rool. This fake K. Rool could somehow fire lasers from its forehead, pop-up all over the place and it also has a high pitched crazy laugh that either comes from the cut-out itself or a nearby, hidden loudspeaker, and is the unofficial ruler of Creepy Castle. As backup, King Kut Out would sometimes send Ghosts to attack the Kongs. Explosive Puftups also prowl the waters surrounding the battle arena.

In order to combat King Kut Out, the Kongs must use the nearby Barrel Cannons to blast into the cut-out. If the shot of the cannon doesn't hit King Kut Out, then that Kong can no longer be used in the fight. Three hits caused the poorly constructed boss's left arm to rip off. With one arm gone, King Kut Out will start to reveal a decoy of itself at the other side of where it's facing. The decoy is darker in appearance, and does not fire lasers. Three more hits made the right arm rip off. After that, King Kut Out began to pop-up and down at a much faster rate. The player must identify where King Kut Out will be, and then enter the correct cannon. If timed correctly, The player will hit King Kut Out. The last three hits made King Kut Out's head rip off, leaving the Kritters with no other alternative but to run away. The Kongs then claimed the Boss Key of Creepy Castle.

Lanky Kong fights first, followed by Tiny Kong, Chunky Kong, Donkey Kong, and Diddy Kong, in that specific order. If Diddy fails to hit King Kut Out, the player will have to restart the battle.
