The Nashville Zoo is using oversized eggs to help two clouded leopard cubs with their hunting and pouncing skills and it's resulting in adorable tumbles.

The brother-sister pair are named Joker and Quinn after Batman characters and are 11 weeks old.

Clouded leopards are native to the tropical lowlands of Southeast Asia in countries such as Nepal and Bangladesh. The zoo says they are considered vulnerable to extinction, according to the International Union for the Conservation of Nature. It's due to deforestation, poaching and pet trade.

There are 62 clouded leopards at zoos that are members of the Association of Zoos and Aquariums, with Nashville Zoo housing 14 of them.
