Mosha, a three-legged Asian elephant, just got an upgrade.  The nine-year-old pachyderm was fitted last week with a prosthetic leg at the elephant care center that has been her home for most of her life.  In 2006, at just seven months, Mosha stepped on a land mine in Thailand and lost part of her front right leg.  Two days later the Friends of the Asian Elephant Hospital at MaeYao National Reserve in Lampang, northern Thailand, took Mosha in to treat her injuries. There she slowly recovered and began learning how to get around on three legs.
