Vibrant GBA graphics and a zany backstory propel a puzzler based on the familiar premise of matching colors.

More than a million years ago, earth was populated by uniformly sweet-natured civilizations. An evil alien scientist imprisoned all. Bau, Bam and Bom, the cute but powerful heroes, have escaped and resolve to smash the crystal cells that imprison their fellow earthlings.

Like chameleons, the three B's can change colors. This is a highly useful skill, because they can't smash a gem until they change to its color. Once all the gems are smashed, a puzzle is solved. Simple plan, but not an easy one.

Power-ups can shatter multiple gems, bestow bonus points and more.

Play in Story Mode or the timed Arcade Mode. Two GBAs, a GBA Game Link cable and two Game Paks are required for the multiplayer Vs. Mode.

Progress is saved to the Game Pak's memory.
