Cool pop-culture penguin crossover, but it lacks more levels, and more penguin characters, like Pengo, Happy Feet, Wallace & Gromit Penguin, Linux Penguin or Günter (from Adventure Time).
About penguin pokémon, it should also add normal Delibird, Piplup and its evolved forms (Prinplup & Empoleon) & Eiscue.
P.D: And Madagascar penguins (Skipper, Kowalski, Private & Rico).
