Berlin ? A German court has told the Berlin and Neumuenster zoos to settle a price dispute over Knut, pictured above, the polar bear who took the world spotlight as a fuzzy white fluffball.

The Berlin Zoo offered $476,420 on Tuesday for the now grown 2-year-old bear. Neumuenster rejected that, insisting it wanted twice that amount for Knut, the son of its polar bear Lars.

The court ordered the two sides to agree by July 13.

Neumuenster is seeking to force the Berlin Zoo to openly state how much it has made in royalties from Knut, whose image has been reproduced in posters, books, a movie and countless stuffed toys.

Knut’s fans boosted Berlin Zoo attendance by 27 percent in 2007 alone, bringing in some €6.8 million.
