Video: Pandas' first one hundred days captured in time-lapse The video shows the first 100 days of the cubs' lives, as they change from small, pink, bald babies, to creatures that look like miniature pandas. The cubs were born on 15 July and, in keeping with Chinese tradition were named on their 100th day on October 23. The twin male cubs are called Mei Lun and Mei Huan, names which mean "something indescribably beautiful and magnificent." The twins are the first surviving pair of giant panda cubs ever born in the USA. They are also the first pair of twins born in the US in over two decades.
