From GameSpy.Com:
Wrapper in a sci-fi back story, this puzzle game stars the creatures BAU, BAM and BOM who, as Gem Smashers, travel the world to spring, spin, and smash the crystal cells where their friends are imprisoned. It's up to you to help our little heroes survive. Use their magic energy which makes them change colors -- it is only possible for them to break down the gems and free their friends if they are the same color as the gem.
