Twenty-three adorable newborn panda cubs have debut publicly in the Chengdu Research Base of Giant Panda Breeding in China on Thursday.

The adorable lumps of black-and-white fuzzballs, which were introduced for the first time in the mainland, are all under four months old and were caught snoozing on stage in a central China province Sichuan while hundreds flocked to the breeding facility.

The youngest cubs include a male and female twins born to giant panda Chenggong on Aug. 9. Another male cub was born to giant panda Dajiao on Aug. 15 and on Aug. 19, another male cub was born to Chengji.

As part of the Chinese tradition, giant panda cubs remain unnamed until they reach 100 days old.

During the event, some pandas took a nap while people were enjoying watching them, with one cub caught yawning as spectators tried to capture the capture the moment.

Meanwhile, another panda cub stole the show when it fell off the stage, appearing to land on its head with legs in the air. However, a handler was quick to catch it then brought back on the platform.

The event was held to celebrate an increased number of pandas at the Chengdu Research Base of the Giant Panda this year. A total of 27 baby pandas, which include four born overseas from pandas on loan, were born this year, a figure twice those born in 2015.

Experts say that the baby-boom can be attributed to improvements in breeding technology at the base, Inside Edition reported. The breeding center is one of several captive-breeding programs for giant pandas around the world, including the United States. 

On Sep. 4, conservationists said that the increased in population, panda’s “endangered” status was downgraded to “vulnerable” on the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species.

However, IUCN still pointed out that pandas still face threats from climate change and reduced bamboo availability which means that they may eventually lose their natural habitat, according to Irish Examiner.
