Orca Slap is a really fun game with really nice graphics. You play the role of a Yeti. Your aim is to smash the penguins in to the dartboard by hitting the penguins with a snowball. Try and time your throw as the penguins are starting to fall back down. You can score more points by making it as close to the center of the target as possible... The funniest part is that the penguins seem to enjoy the whole thing.
