chocobo
Trademark steed of the Final Fantasy JRPG series by Square Enix (formerly Squaresoft).
They are large birds resembling some cross between a chicken and an ostrich or other ratite. Often used as mounts (in the abscence of horses). Primarily yellow, though other colors (and sizes) are known. They make "kweh" and "wark" noises. Baby chocobos are "chicobos" ("ko-chocobos" in Japan). In most games, they are flightless, but other games gave them the ability to fly and swim.
A chibi version heads up the Final Fantasy Fables/Chocobo series.
