Kass is a Kremling (possibly Kritter) child and a playable character in Donkey Kong Barrel Blast. She was made to rival Dixie Kong, and as such she has the same racing stats as her. Kass is also the first known Kremling to be explicitly female. She is one of the few Kremlings, a trait that she shares with Kalypso and Kasplat.
Kass also makes an appearance in Super Smash Bros. Brawl, in which she is one of the trophies. Her trophy states that she wants to grow up and has a fear of frogs, especially Winky.
