This vigorous fellow is named Potkis, which translates to something like 'the Kicker', thanks to his uneasy legs. He actually was supposed to be the star of the penguin game I ever planned to do, back mid-1990s and glory-days of game creator tool 'Klick & Play'. The game was meant to be a Mortal Kombat clone with penguins, but my design simply was too huge for me back then and I scrapped it.
