Klaptrap

Klaptraps are Kremlings that originated in Donkey Kong Country. They are lizard-like creatures with large mouths, hence their name. They cannot be killed by a front attack, but they vunerable to a stomp. They come in blue and red varieties.

Klaptraps later appear in Donkey Kong Country's semi-sequel Donkey Kong Land. Klaptraps were relatively unchanged in this appearance.

Klaptraps did not appear in Donkey Kong Country 2: Diddy's Kong Quest or Donkey Kong Land 2. Instead extremely similar creatures, called Klampons appeared.

Klaptraps did not appear in Donkey Kong Country 3: Dixie Kong's Double Trouble or Donkey Kong Land 3, once again they were replaced with similar creatures called Krimps.

Klaptraps finally made a return in Donkey Kong 64 here they were given a new ability, once a Klaptrap is defeated it's skeleton will continually attack the kongs until it is destroyed. Also introduced in the game were Giant Klaptraps, these Klaptraps were slightly larger than the kongs and could only be defeated with an orange grenade. Interestingly one of Donkey Kong 64's cutscenes showed King K. Rool with a small Klaptrap that seemed to be his pet.

Also in Donkey Kong 64 a Klaptrap is playable in the mini-game "Beaver Bother", this marks the first time a Klaptrap is playable.

Klaptraps also appear in Donkey Konga.

Klaptraps may be based off Snapjaws, crocodilian enemies Mario would send after Donkey Kong Jr. in the game Donkey Kong Junior.

Klaptraps also occasionally appeared in the Donkey Kong Country animated series. Here they were mainly used as ammunition for Klap-Blasters, weapons that fired Klaptraps like projectiles. On the show Klaptraps had a hunger that could almost never be sated, they would eat anything even wood or metal. Unlike the Klaptraps in the games the Klaptraps on the show could speak, though they ussually just talked about what they wanted to eat.

The show also introduced a character called Junior who was an abnormally large Klaptrap that wore dentures.

Appearances In Other Games
Although Klaptraps generally stay in Donkey Kong games, they occasionally visit the Marioverse. Klaptraps are distractions in Donkey Kong's course, in Mario Superstar Baseball Klatraps try to bite the outfielder's heels, slowing them down. However, if you were to hit the baseball into a Klaptrap's mouth, it would give you a Team Star.

Klaptraps also appear in Mario Power Tennis in Donkey Kong's court. They try to bite the player, causing the player to slow down. Klaptraps also appear in the mini-game Ballon Panic, here the player must protect several balloons from hungry Klaptraps. Klaptraps make a cameo in Mario Party 7 as enemies in one of the Pyramid Park events.

in Super Smash Bros. Melee Klaptraps appear in Donkey Kong's stages. They would swim through water and attempt to bash a character into the abyss.

Appearances In The Donkey Kong Country Animated Series.
In the Donkey Kong Country animated series Klaptraps were, instead of soldiers, ammunition for a weapon called a Klap-Blaster. Unlike the Klaptraps of the games the ones on the show were capable of speaking, often times when a Klaptrap was seen it would make a sarcastic comment about it's job or what it had just eaten (similar to the various animals featured on The Flinstones cartoon). The show also featured an abnormally large Klaptrap named Junior the Giant Klaptrap.
