A couple red panda cubs got to see snow for the first time in their lives at a Tennessee zoo.

Zoo Knoxville officials say the brothers -- named Mr. Darcy and Dr. Wallace -- explored their habitat, enjoyed a snack and even a short nap in the snow flurries.

The zoo says red pandas are perfectly built for cold weather. They are native to the temperate mountain forests of the eastern Himalayas and southwestern China.

The pair were born June 3. Since then, the zoo says the brothers have been thriving.
