Ammon News - Berlin's newest panda twins have celebrated their first birthday with frozen vegetable treats and a candle made out of bamboo shoots.

The two female cubs were born at the Berlin Zoo on August 22 last year, and each was given both a Chinese and a German name. Meng Hao and Meng Tian are better known as Leni and Lotti, tributes to Berlin native Marlene Dietrich and the German capital’s Charlottenburg district.

On Friday, the cubs played around and with a large red wooden figure 1. They were given what the zoo called “ice marbles” made of beetroot and carrot juice.

The young pandas, who weighed under 200 grams (7 ounces) at birth, now weigh in at about 21 kilos (46 pounds) each. Their keepers are already noticing character differences: the zoo says Lotti is the more daring of the duo, while Leni is often more laidback.
