Neighborhood security guard #1 sees terrapin being hit by a car, someone tell him that we have terrapins in our backyard (probably the old guy that everyone hires to help with gardening) and brings it to us.
Neighborhood guard #2 comes to our house and says "I heard you ladies take good care of these guys, and I found this one being tumbled by a water current from the recent storm." and gives us another terrapin.
So now we have 6 adults and the three babies born here.
We tried. We really tried. But we can longer avoid naming the new terrapins after Ninja Turtles...
