Hamtaro: Rainbow Rescue is a Nintendo video game for Game Boy Advance and the sequel to Tottoko Hamutaro: Tomodachi Daisaku Ikusa Dechu (Japan only), Hamtaro: Ham-Hams Unite! and Hamtaro: Ham-Ham Heartbreak. Therefore, it was the third Hamtaro game released in Europe, but the fourth one in Japan; the game has not been released in the U.S.A. It was released in Japan on May 23, 2003 and in Europe on October 29, 2004. The series is based on the manga Hamtaro, written by manga-ka (comic artist) Ritsuko Kawai.

The game involves an extensive plot. One day while playing outside, Hamtaro and Boss suddenly witness a great rainbow. Off the rainbow slides Prince Bo. The Prince states that he can make rainbows by using his umbrella. He tries to prove it to the disbelieving Boss, but realizes too late that the colors on his umbrella are gone! And thus, Hamtaro and his Ham-Ham friends must set off on a journey in order to collect things that are the proper colors for Prince Bo to use for his umbrella so he can create a rainbow to return home. Check out the following codes to ease in case you want to have more fun playing the game:
