Crowds gathered at Berlin Zoo on Easter Sunday, many of whom gathered round the enclosure of star attraction Knut, the baby polar bear who has charmed crowds across Germany and worldwide.
Knut, who was born at the zoo on 5 December, has already captured the hearts of Berliners and people worldwide, and has his own video podcast and TV series.
The polar bear has spawned a whole money-spinning industry of souvenirs, from cuddly toys to sweets, from musical releases to mugs and T-shirts bearing his image.
Last month, Berlin Zoo registered the celebrity cub as an official brand, enabling it to make money from the various Knut-themed spin-offs.
Knut is on show for two hours a day, and his enclosure is surrounded by adoring fans watching his antics.
Heiner Kloes, bear curator at Berlin Zoo, said Knut is growing very well and getting more and more curious by the day.
"He is gaining weight - 300 grams daily. He is fed about 1200 to 1300 millilitres of nutrition mix. Meanwhile, he likes to nibble some bread, some grapes and everything he sees," he said.
Knut has been raised at the zoo since his mother rejected him and his brother, who died shortly after their birth.
