Hamtaro: Rainbow Rescue (とっとこハム太郎4 にじいろ大行進でちゅ) is an adventure video game developed by AlphaDream for the Game Boy Advance and the sequel to Hamtaro: Ham-Ham Heartbreak. It was released in Japan on May 23, 2003 and in PAL regions on October 29, 2004 (though copies were poorly distributed in some countries, making the game rather rare). It was set to be released in North America in 2005, but was cancelled for unknown reasons.


One day while playing outside, Bijou witnesses a great rainbow. The rainbow disappears and Prince Bo falls to the ground. The Prince states that he can make rainbows by using his umbrella. He tries to prove it to disbelieving Stan and the rest of the Ham-Hams, 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 color for Prince Bo to use for his umbrella so he can create a rainbow to return home.


Gameplay is similar to past entries in the series, except with the addition of being able to control multiple hamsters at once. Certain minigames are needed to be beaten in order to reach the colors and the player must have specifc Ham-Hams in their party in order to play them.

In addition to the original Ham-Hams, the game contains characters that are never seen in the English dub of the anime, including Prince Bo, prince of Rainbowland; Flora, or Nurse-Ham; Tux; and other various characters.


  • You can also collect stickers and coloring sheets that you earn in mini-games and after finishing quests.
  • After finishing the main storyline (getting all of the colors), you are tasked with inviting all of the ham-hams to the Rainbow Theater.
  • A few of the sound effects were reused from Tomato Adventure, another AlphaDream game.
