Ghost is a rather special copy ability only playable in Kirby: Squeak Squad, obtained from the mini-boss Tedhaun, who replaces one mini-boss from each level after completing the Ghost Medal. Ghost Kirby cannot pass through solid objects, not even up through floors or down ladders where normal Kirby can, but it lets Kirby directly take control of certain enemies and use their abilities as his own, instead of copy abilities. This easily gives Ghost the largest number of possible moves in the series.

One of Kirby's six Animal Friends. Rick is a roly-poly hamster, almost as large as Nago, and equally roly-poly cat. Rick made his debut in Kirby's Dream Land 2, and like all Animal Friends, he shares and augments Kirby's Copy Abilities. Rick's personal relationship is with his love interest, Pick. Rick appears in Kirby: Right Back at Ya!, living beneath the roots of Acore the great tree, but his relationship with Kirby isn't what it was in the preceding games. Kirby and Rick are rarely seen together, and directly interact even less, but they are still friends nonetheless.

Drawcia is the main villain in Kirby: Canvas Curse. She is born out of a mysterious painting, out of desire to rule a world of canvas and paint, and wields the mighty Power Paintbrush. She initially overwhelms Kirby, turning both him and Dream Land into canvas and paint. Luckily Kirby manages to touch the Paintbrush and acquire some of its power, and uses his new-found strength to defeat Drawcia at her own game.
