K. Lumsy's Prison is a location that appears in Donkey Kong 64.
K. Lumsy's Island is a rather small prison located right beside Crocodile Isle. This is where King K. Rool kept K. Lumsy locked up after the latter refused to destroy DK Isles. There is a Bananaport 1 pad located here where the Kongs can warp right from DK Isles to here and vice versa. The Kongs can also come here whenever they receive a Boss Key and K. Lumsy will unlock the way to the other areas. There are also two Golden Bananas that can be earned here. Both as Lanky Kong as one is located outside of the prison that requires his Grape Shooter to get into and the other is inside that requires his OrangStand Sprint.
