Kirby is a small pink spherical creature with two stubby arms, two red feet and two oval-shaped eyes with black pupils (with a faint shade of blue at the bottom starting with Kirby Super Star, which was brightened in later appearances). Kirby's cheek-blushes weren't introduced until his second game, Kirby's Adventure, where they appeared as two black whisker lines in artwork. In subsequent games until Kirby 64: The Crystal Shards, they were depicted as three red diagonal lines in artwork.
