That penguin looks badass.
Had a shot on this game, looks pretty playable without Japanese skills. After some intro set in a classroom involving some hilarious facial expressions it becomes a platformer where you can jump, punch, do a Guile-style flash kick special (that depletes a bar at the bottom of the screen) and a Castlevania jump-back move. You go around killing things (cupcakes?) until you find another penguin, you take him into a tree stump and fuck his shit up, fight club style.
