The zoo where they live in Vienna, Austria, threw the siblings a party and showered them with gifts including boxes of their favorite foods – sweet potatoes and carrots.

The cubs' mom Yang Yang and Fu Ban, which is Chinese for "Lucky Companion," were more than happy to tuck into the snacks, while Fu Feng, which is Chinese for “Lucky Phoenix,” stayed in the cubs' enclosure.

Visitors packed around the pandas' home at Tiergarten Schoenbrunn to watch them enjoy their treats.
