A 14-week-old polar bear cub sticks out its tongue at the camera while playing with its twin on March 19 at the Hellabrunn Zoo in Munich, Germany.
The cuddly duo — a boy and a girl born at the zoo on Dec. 9 — accompanied their 7-year-old mom, Giovanna, on an exploration of their enclosure as part of their first presentation to the media.
You may remember Giovanna for being the former "love interest" of Germany's most famous bear, Knut, who died of encephalitis-induced seizures in 2011. Although their romance didn't pan out the way keepers and staff had hoped, Giovanna remains in good health and has gone on to mate with the zoo's 14-year-old male, Yogi.
