Mother 1+2

"Mother 1 + 2 (MOTHER 1+2 Mazā Wan Tsū) is a port release of Mother and EarthBound (Mother 2 in Japan) of the EarthBound series for the Game Boy Advance. Released exclusively only in Japan on June 20, 2003, by Nintendo, a bonus cell-phone strap of Mr. Saturn was included for pre-ordered packages of the game. Though the strap was originally intended only for those who had pre-ordered the game, its popularity caused it to be sold briefly on amazon.co.jp. It was re-released as one of the Value Selection games on February 2, 2006."
