If you don't know, Umihara is a grotesquely cute-looking game for the PSP where you guide a child around a brightly colored block-like world while fighting off and evading fish monsters. The girl probably eats a lot of fish, so she has nightmares about them trying to eat her or something. Truth is, we don't know -- but we do know there's a new trailer on the official website. Check it out and have your heart melt a bit. It looks fun.
