But "brother" panda may be wondering, "Where's my sister?"

Turns out she didn't show up to the party.

The zoo says she is very shy and feels more comfortable inside, away from all the people.

Brother on the other hand is extremely playful.

The zoo says he's a total cuddle-bear just like his dad.

His name is "Fu Ban", Chinese for lucky companion. His sister's name is "Fu Feng," which means lucky phoenix.
