Klaptraps are small Kremlings found in Donkey Kong Country, Donkey Kong Land, and Donkey Kong 64 as commonly found enemies in the games. They scurry quickly along the ground, jaws clapping together just waiting to bite into a Kong. They usually have a small walk cycle where they patrol back and forth along it. One well-placed jump by either Donkey Kong or Diddy Kong will eliminate a Klaptrap. In Donkey Kong 64, if a Klaptrap is hit, their teeth will continue to chase after the Kong but the teeth can easily be defeated by another hit or just avoiding them until they break apart.
Purple Klaptraps are found in very few levels but are almost more lethal than regular Klaptraps. When Donkey or Diddy Kong jumps up, the purple Klaptraps jump up too. The Kongs must time their jumps appropriately to land on them to take them out. Purple Klaptraps occur most numerously in the Loopy Lights level.
When Klaptraps are encountered in bonus levels, one hit does not take them out. When jumped on, they release bananas and their walk cycle speeds up every time they are hit. The Kongs need to be careful when jumping: they walk very fast - it is very difficult to hit them. When the Kongs defeat the Klaptrap, they receive a prize such as an Animal Token or an Extra Life Balloon.
