At least he’s the longest time resident at Sea Turtle Inc and is quite the ham. Most of his buddies there have a missing flipper or two, maybe even three as a result of run-ins with predators or ocean trash (boo).  One even has a prosthetic; a rudder to allow her to swim straight and come up to breathe powered with just one flipper.  There are not exactly cuddly critters but something about them makes one want to be sure they are around for the next generation to see.
