Roughly three weeks ago two polar bear cubs were introduced to the public at the Tierpark Hellabrunn Zoo in Munich, Germany. Crowds were thrilled for their arrival but have been waiting anxiously to learn the names of the twin ivory bundles of fur. The wait is finally over. The female cub is now Nela (Nelluh) and the male is Nobby. But it wasn't the staff at the zoo who chose those names. Instead selection of the bears' monikers was done in an unusual way explains Zookeeper, Helmut Kern.
