Klingers are Kremling enemies who have the ability to climb up ropes and then skid down quickly at regular intervals. They first appear in the games Donkey Kong Country 2 and Donkey Kong Land 2.Despite not being considered natural climbers, Klingers are usually featured in stages of the Crocodile Isle in Donkey Kong Country 2 containing vertical ropes, vines, cattails or chains, including the Gangplank Galleon stages Mainbrace Mayhem and Topsail Trouble, the Krem Quay stages Krockhead Klamber and Slime Climb, the Krazy Kremland stage Mudhole Marsh, the K. Rool's Keep stages Chain Link Chamber and Toxic Tower, and the The Flying Krock stage Screech's Sprint. The behavior of these enemies is to climb up single short sections at certain speed, quickly slide down soon after reaching the top and repeat the process. While sliding down, they will also release a loud noise. If Diddy and Dixie Kong have to progress by climbing, the Kongs must avoid contact with Klingers on the way. It could be accomplished by using good timing and moving under these enemies. Klingers can be defeated by the primates jumping on their heads, it being easier to pull off when the enemies have reached the top of rope sections. They can also be defeated by the heroes throwing single barrels, crates, treasure chests, Kannonballs or Click-Clacks at them. Klingers can also be harmed by projectiles attacks from Animal Buddies, such as Squitter the Spider and Squawks the Parrot. Using the team-up move on the ground to throw the secondary character at Klingers will take the enemies down upon contact.

At the opening cutscene of the Game Boy Advance version of Donkey Kong Country 2, when the Kaptain K. Rool uses The Flying Krock to fly over the beach of the Donkey Kong Island, just before Donkey Kong being kidnapped, many Klingers are seen sliding down on two vertical ropes deployed by the airship. The enemies appear to drop down on the jungle of the island.
