Jirachi is a yellow and white Pokémon with small black eyes. Under its eyes, there are V-shaped markings that are light green. Jirachi's head is yellow and resembles a star, but with only three points. Hanging on those three points are three light green bands that are said to be part of Jirachi's ability to grant wishes. It also has two yellow strings streaming from behind it.
Not obtainable by normal means, the only way to get a Jirachi is to download it from a bonus disk that was given out along with a reserved copy of Pokémon Colosseum or (more recently) to download it at a Nintendo-sponsored event, such as the Jirachi that was given out at GameStop stores in the US from February to March 2010. It is in a Cherish Ball and came with the move Draco Meteor.
Jirachi was the title character in Jirachi: Wish Maker where it awakens every 1000 years when the Millennium Comet appears in the night sky. Upon awakening, it became close friends with Max and his friends. Feeling somewhat homesick, Jirachi and its new friends journeyed to its home to put it back to sleep.
Jirachi did not appear during the Generation I - II games.
