Celebrity polar bear Knut is one
Not only is "cute Knut" the polar bear - abandoned at birth by his mother - now in rude health as he marks his first birthday, he has an army of fans and the honour of being a massive marketing success.
Children's street parties, live TV specials and a gourmet cake for the celebrity himself. The first birthday of a polar bear who captured the hearts of millions around the world after it was reported that he nearly died at birth is being commemorated in Berlin today with the pomp and gusto normally reserved for a royal wedding or World Cup win.
Knut, the polar bear whose weight has increased from 810g (28oz) to a hefty 110kg (17st 3lb) is estimated to be the biggest cash-grossing animal of all time.
