Different from the chess piece, this one is bigger and a little more detailed, with cracks in the lips and fur.

At the start of Donkey Kong Country 3, Dixie arrives in the Northern Kremisphere in search of the missing Donkey Kong and Diddy Kong. She goes to Funky's Rentals, where Funky Kong has been reluctantly babysitting Kiddy Kong. The chore is passed on to Dixie, and he joins her in her quest.

Kiddy has great strength and rolling speed (like Donkey and Diddy respectively) and is able to throw Dixie high into the sky. Despite this, throwing him upwards can cause him to break through cracked surfaces because of his weight, throwing him against the wall will make him roll which gives Dixie the chance to jump on and ride him like a Steel Keg, and Kiddy can bounce on water, which compliments Dixie's Helicopter Twirl. When defeated, he pounds the ground with his fists and cries loudly.

In the Game Boy Advance version of Donkey Kong Country 3, due to Kiddy being a toddler, he cannot participate in the Swanky's Dash, a fast-paced virtual reality game.
