The Berlin Zoo's polar bear cub, Knut, has risen to fame ever since his picture appeared on Vanity Fair cover with Leonardo DiCaprio. The cub, which has his own line of souvenirs now, has nearly 15,000 people come to the zoo every day.

The 4-month-old polar bear has stuffed toys selling in his name at the rate of 800 a day. Not only this, the amazingly adorable cub also has T-shirts, key chains, coffee mugs and other kitsch to his name in the market.

According to The Guardian's UK edition, Haribo, the German confectionary company, has created a white, marshmallow-like Knut sweet that is expected to hit stores across Germany and Austria next week.

Knut even has his own blog in German, English and Spanish, written by a journalist at the regional public broadcaster Rundfunk Berlin-Brandenburg. Berlin zoo's stock is currently shot up as high as $6,400 this week.

However, zoo authorities believe that the popularity should be cashed in on soon because the cute cub's popularity is soon going to end when the cub grows into an adult polar bear, which can be ferocious.
