Two 4-month old polar bears at a zoo in Germany finally have names. The boy was named Nobby and his sister was named Nela.

The two polar bears spent the day running around in their enclosure.

The playful twin cubs were born to Giovanna and Yogi on December 19.

Their honorary godparents, a businessman and a wildlife photographer, decided on the names.

All animals born at Munich's Hellabrunn Zoo in 2013 have names starting with the letter "n".
