Baboo: Rainbow Puzzle

Some games are just too cute for their own good and 'Baboo: Rainbow Puzzle' is one of them. It's a relatively classic puzzle game, where you drag pieces (made of cartoon animals' little heads) in order to fill rows in the play field. You can call it a lazy Tetris clone, since it's all the same except that pieces do not fall, but you drag them yourself. When you fill the row (disregard the color of pieces), animals disappear with a too-cute sound (I guess they're happy when that happens).
