Keeby is a Kirby character who's only official appearance was in the Japanese instruction manual for Kirby's Dream Course. Representing player two, Keeby is a yellow Kirby with orange feet. He was based on a suggestion made by Shigeru Miyamoto during the development of Kirby's Dream Land for Kirby to be yellow instead of pink.
Although yellow Kirby would go on to be a mainstay in multiplayer Kirby games as well as the Super Smash Bros. series, none of these have been officially identified as Keeby.
In Kirby's Dream Course, the second player plays as Keeby in multiplayer mode, and he has identical abilities to Kirby. As he is not seen outside of Kirby's Dream Course's multiplayer mode, he is a somewhat obscure character in the Kirby series. Though not Keeby exactly, his yellow and orange color scheme is used as an alternate coloration for Kirby in Super Smash Bros.
