Krunch the Kremling is a Kritter-like playable character in Diddy Kong Racing and Diddy Kong Racing DS and member of the Kremling Krew and he is also surprisingly a friend of Diddy Kong.
Diddy Kong Racing
Krunch's first appearance is in the game Diddy Kong Racing. Here Krunch is sent by King K. Rool to investigate why Diddy Kong and several of his friends are at Timber's Island and to see if they are hatching some sort of anti-Kremling plot. Instead of antagonizing Diddy and his friends, Krunch ends up aiding them in their battle against the evil alien hog, Wizpig. Krunch has the worst acceleration and handling in the game, but has a very high top speed, making him the 3rd fastest racer.
Diddy Kong Racing DS
Krunch finally makes a reappearance in Diddy Kong Racing DS; he seems to have somewhat of a bullying attitude in this game. Krunch is left relatively unchanged from the Nintendo 64 version, but his changes are a small boost in his turning and acceleration. In the Nintendo DS version, Krunch has a twin relative in the first scene.
