A penguin named Mr Munro fails in its first attempt to leave its footprint on a white canvas at Taronga Zoo in Sydney June 27, 2012. Keepers at Taronga Zoo have been collecting the footprints of almost 4,000 animals to make their mark and pledge their support for the wild, and the zoo announced its commitment to an elephant protection project in Thailand's Kui Buri National Park.
