Carrie is the tenant in Apartment 202 in Dom Woole's apartment building in Quilty Square of Patch Land in Kirby's Epic Yarn. She offers a small collection of minigames where Kirby has to carry her to a certain location within a time limit, after Kirby decorates her room with the appropriate furniture obtained from the various Treasure chests in the game. Like all the other tenants, she sometimes visits Kirby in Kirby's Pad, and she offers a secret fabric after all his minigames and the main story has been completed.
Perhaps the most iconic villian of the Kirby series, King Dedede has been around and in Kirby's way since Kirby's Dream Land, the first ever title to be released; the only game to not feature him as of 2011 is Kirby & the Amazing Mirror. He is a rather portly penguin-like character, wielding his iconic barrel-headed hammer with the star embelm.
While not inherently evil, Dedede causes all sorts of trouble in Dream Land, such as taking a bath in the Fountain of Dreams. While his everyday actions make it seem otherwise, he takes the safety of Dream Land very seriously, and although his plans are not always known by or agreed to by everyone, it is arguably effective, such as Dedede stealing the Star Rod and breaking it up, simply because he wishes it to be outside of Nightmare's hands.
In Kirby: Right Back at Ya!, his character is rather more shallow and dim-witted than depicted in the games, and seeks to straight-out humiliate and defeat Kirby just because he wants him away from Cappy Town. His plans backfire far more often than is healthy for Escargoon and himself, however.
