Kirby was going to be a little yellow gumball
Kirby is occasionally shown in yellow; you might have seen him this way in Super Smash Bros., or perhaps in Kirby Air Ride. This yellow Kirby is often said to be a reference to the fact that legendary game developer Shigeru Miyamoto originally wanted Kirby to be yellow. Kirby creator Masahiro Sakurai, however, wanted him to be pink.

The argument between yellow and pink must have raged on for quite some time. Nintendo of America, apparently ignorant to Kirby's true colour, opted to make Kirby white on the box of his first game, the monochromatic Kirby's Dream Land on the Game Boy. He was pink by the time Kirby's Dream Land 2 rolled around, however, where Kirby was shown on the cover riding a giant hamster. So awesome.

Thinking about it, a yellow Kirby would probably end up looking just a little bit like Pikachu and Starlow
