People often throw coins into ponds to wish for luck, but for a green sea turtle that was living in a park pond along the coast of eastern Thailand, good luck was not what she received.

After consuming 915 coins, amounting to 11 pounds, the 25-year-old female turtle died.

Nicknamed Omsin, meaning "piggy bank," the turtle was first rescued by a member of the Thai navy last week, who saw her showing signs of distress. After being brought to a veterinary clinic, Omsin received a four-hour surgery to remove the coins.

The turtle initially appeared to be doing well, but a second surgery was required a week after the first to repair the animal's damaged intestines.
