here ya go I found this game review for ya, most of the reviews said similar this one was most detailed
In Xia Xia for the Nintendo DS you explore oceans and beaches with your little hermit crab. The game offers you the favorite Xia Xia hermit crabs for you to use and I just love each unique collectible shell. There is Bimini, Tobago, Trinidad and Turks, all in this game. There are numerous missions to set off on among the 25 levels and along the way you are tested with unlocking secret rewards and finding collectible shells to advance. So one does not get board easily and looks forward to reaching each new level. Overall I give XIA XIA for the Nintendo DS 5 stars for its ease of use, fun game play, and lets not forget the cuteness factor. Xia Xia would make a great gift for girls of any age.
