I have a recent turtle story as well.
We flew the Cardinal over to KCLL (College Station) last weekend for my Niece's graduation.
Approach wasn't busy, so I asked for a practice RNAV approach into the field. They complied and vectored me in.
When they transfer me to tower, the first thing they tell me is to be aware of turtles on the runway. After a few seconds of confusion on my part tower told me that the previous landing plane had nearly hit a fairly large turtle crossing the runway.
Fortunately I was able to easily miss the turtle, and they got a "rescue" truck out right after I cleared to help the turtle out.
