Keep the change, please.

Vets in Bangkok had to do surgery on a sea turtle named “Piggy Bank” on Monday, successfully removing 915 coins from her belly. The 25-year-old turtle had difficulty swimming after swallowing 11 pounds of objects, including two fish hooks, that had been thrown into the pool she lived in by visitors who treated it as a wishing well.

“It is hard to imagine how it swallowed such a large number of coins. I’ve never seen such a case before,” one of the vets told the Bangkok Post.

Thais have been captivated by the turtle’s fate after a 3D scan revealed that her shell had been cracked from the load. The public raised almost $430 for her surgery, which vets at Chulalongkorn University say could have been the first of its kind. Doctors say that the turtle will probably require a month of recovery and another half a year of physical therapy before getting back into fighting shape.

The recovered stomach stash reportedly included both foreign and local coins. This is not the first time that badly behaved tourists have involved animals in their foreign shenanigans. Two inebriated U.K. tourists stole a celebrity penguin from an Australian theme park in 2012, landing themselves with a hefty fine. Given that a 2015 Oxford University study found that most people visiting wildlife attractions don’t realize their actions have an impact on the ecosystem, it’s hardly surprising that urban tourists are oblivious to the effects of dunking their change in a pool.
