He may not have blown out any candles, but Washingtons famous giant panda off-spring, Tai Shan, officially celebrated his fourth birthday this morning -- complete with singing, guests and a massive, three-tiered veggie-sicle cake. The frozen masterpiece was made over the course of two weeks by Zoo commissary staff by freezing a combination of water, beets and beet juice while enhancing it with bamboo and fruit. Tai quickly took to the frozen treat, licking at the ice, spotting his furry face with the melting beet juice. Tai Shan is on the cusp of adulthood; at age four, he is considered a teenager in bear years.
