Don't throw coins near turtles:
Veterinarians laboured for seven hours to remove 915 coins weighing five kilogrammes from a sea turtle suffering chronic stomach ache. [...] Last month, Om Sin, Thai for piggy bank, was sent to the faculty from the Sea Turtle Conservation Centre of the Royal Thai Navy in Sattahip district in Chonburi last month after it barely swam. A CT scan at the university shocked vets when they saw the mound of coins. [...] According to Thai belief, throwing coins into a turtle pond would stop bad luck.

For some reason this caused my mind to conjure up an image of turtles starting to mugging each other and soon end up dressed as pimps whilst waging gang wars.
A more likeky outcome, howver, is turtles starting to mug people.
Either way I'm in favour of and look forward to this
