Nuremberg, Germany  - Prime time arrived Tuesday for Flocke, a four-month-old cub at Nuremberg Zoo which already has its own website and is set to take over the role of Germany's most adorable polar bear.

Television teams from all-news channel CNN and Japan's Fuji TV were in the media scrum waiting at the zoo, which expects up to 25,000 visitors a day this summer to see the fluffy white cub's antics.

The cub's name, which means Snowflake, was chosen in a national competition at the start of the year after the little female was rescued from its agitated mother and hand reared by zoo keepers.

The Flocke story is a sequel to the media sensation over Knut, last summer's male polar-bear cub in Berlin which has since grown into a less attractive moody adolescent. Germans are wondering if the two bears could one day mate as a dream couple.

Tuesday's debut by 20-kilogram Flocke was reserved for 360 accredited journalists and 50 VIP guests of the Bavarian city of Nuremberg. The public will not be admitted to see the cub till Wednesday.

An animal-rights group wearing white bear costumes picketed the zoo Tuesday, contrasting the personification of the bear with people's disinterest in the extinction of other animals caused by the human takeover of their habitats.

"Flocke is being used as a screen to project frustrated human emotions onto," they said in a news release.

The Nuremberg Zoo has rebuilt its car parks, rest-rooms and ticket-booths to cope with the expected rush this summer, and will usher visitors through a grandstand next to Flocke's watery den, with viewing limited to 15 minutes for each contingent of 500 to 600.

While asleep, Flocke can be seen on big screens, and the zoo has set up a website with detailed news on the cub's development.

Keepers initially wanted Flocke to be raised by its own kind, but the mother bear, Vera, became agitated on January 8 as media attention grew and camera crews were filming the den.

When the mother kept roughly dropping Flocke and picking it up again by the nape of its neck, keepers guessed an act of violence was imminent and seized the cub. (dpa)
