Three cheers for Shan Tou and Yukiko! The rare red panda couple are the proud parents of triplets born at the Red River Zoo in Fargo, N.D., on June 11.

And the still-to-be-named panda babies are quite the big deal. "The last time triplets were born in North America was 10 years [ago]," the zoo's animal keeper, Marcy Thompson, tells PEOPLE Pets, adding that last year the pair had twins — two of the five red pandas born in all of North America in 2008.
