The Happy Hills lead a joyous existence in the fantastic land of Euphoria. Life is an endless party until nasty blocks start raining down upon their heads and spreading a foul mood throughout the land. You have only a limited number of bombs to remove the blocks from the Happy Hills; heads. Free the Happy Hills and become their hero!
