The Duke and Duchess of Cambridge have been married just a week and have already adopted -- a baby Humboldt penguin named Acorn. According to Yahoo News, the Chester Zoo, located in northwest England, gave the penguin to William and Kate as a wedding present after asking through social networks which of their 400 different species the couple should adopt.

A spokesman for the zoo commented, "It's a real honor to be able to boast Prince William and Kate as penguin adopters."

So will the newlyweds be hearing the pitter-patter of little flippers running through their Castle? Sadly, little Acorn must remain at the zoo with the 49 other Humboldt penguins.
