Wrinkly Doors are special instances featured in the game Donkey Kong 64. These objects look like oval, wooden doors in a colored frame and have Wrinkly Kong's face imprinted on them. The Kongs can get in contact with the deceased Wrinkly Kong through them. They are found in the lobbies of the regular worlds and their purpose is to give advice to the player, so they can play the game more efficient.
Wrinkly's Doors are present in the lobby of every regular world featured in the game, except for Hideout Helm. Five of them can be found in each lobby. When the player approaches one of the doors, a ghostly image of Wrinkly Kong will appear, accompanied by an eldrich howl. The ghost of Wrinkly will then give the player a hint, how they can find a specific Golden Banana in the level. The color of the door's frame shows which one of the Kongs can retrieve the banana. After giving advice, Wrinkly will go back behind the door with another spooky noise.
Wrinkly's advice is only available if the respective Kong has already been freed of King K. Rool's custody. If the Kong belonging to the door's color has not been unlocked at this moment, the door will show a big question mark with the corresponding Kong's color instead of Wrinkly's face.
In the lobby of Angry Aztec, Chunky Kong's Wrinkly Door is initially not available. Tiny Kong needs to shoot a Feather Switch in the lobby to open up a small room with two Zingers and a black switch. Once the player defeats the Zingers, a Chunky Barrel will appear next to the black switch. Chunky can then use his Hunky Chunky ability and Simian Slam the black switch to reveal his Wrinkly Door.
In the lobby of Crystal Caves, all Wrinkly Doors are blocked off by big blocks of ice. Inside a cave in the lobby, Chunky can pick up a boulder and put it down on a switch in the center of the lobby that will move the ice blocks, making the Wrinkly Doors accessible.
