Lucky is a Humboldt penguin born at the Santa Barbara Zoo in April 2010. As he grew up, zoo keepers noticed that he walked with a limp. Further testing showed that his leg was not developing properly. If not helped, he would eventually suffer from infections from the sores on his feet. Teva, a sponsor of the zoo, was called in to help. The footwear company custom created a boot that would assist Lucky when walking and swimming.
