Purple Klaptrap

Big Klaptraps are large versions of Klaptraps.

Big Klaptraps are found in several areas in Donkey Kong 64, first appearing in the area Angry Aztec. Big Klaptraps are so big that most attacks don't affect them at all (even the Kongs' shockwave attack is useless). Fortunately, they can be defeated by blowing them up with an orange grenade. When destroyed, a Big Klaptrap will leave three orange grenades behind. All of them are colored purple, but some vary in size.

Unlike their smaller brethren, the skeletons of Big Klaptraps will not leap from its body and attack the Kongs when a Big Klaptrap is defeated.

On the Donkey Kong Country animated series a character called Junior the Giant Klaptrap would occasionally appear. Despite his name, Junior was not as big as a regular Big Klaptrap, instead he was about the size of Diddy Kong, whereas most Giant Klaptraps are about as large as Donkey Kong.

Trivia

 * The Big Klaptrap bares a small resemblance to Donkey Kong Country 3's Krimp. They're both purple, but Krimps are not as tough.
