Well, there are always solutions, by giving him a weapon (a fish blade), that could give him an extra reach. Plus if I remember the Happy Feet penguins and the Madagascar Penguins (AND the Pebble and the Penguin penguins) were very mobile despite poportions. There's also Penguinmon from Digimon, a penguin fit for battle.
In this case, you can most likely use him as an assist, but as for the stance he looks like he's twisted his foot in one of the legs.
