Toronto's pandas have officially entered their terrible 2s

The city's largest (and fluffiest) two-year-olds had a birthday party fit for their giant status Friday.

Jia Panpan and Jia Yueyue played with boxes, ate treats and frolicked in their yard at the Toronto Zoo to mark two years since they became Canada's first giant panda cubs.

The zoo opened the party up for television cameras andreleased a video of the cubs and their parents playing in their pen.

Happy birthday!
