Above you see a bank note of the penguins' money. The penguin on that bank note is King Charles XII.
The background of the picture consists of the repeated sentences "It is prohibited by law to forge money or to pass counterfeit money. Any violation will be prosecuted with the ban from Penguins not under 20 years." in both English and German (Penguins is a bilingual country).
It might be worth noting that the penguins' money does not have a unit name as other currencies have (e.g. "Euro", "Dollar", or "Pound Sterling" for the European, American or British money).
