As a precaution, I've put the remaining "Looks like Originals" class member in a container with a low water level to avoid the risk of drowning.  Like some others, the fella likes to act as a Tree Frog and scale the sides (I'll try to get a photo of it.)  I'm waiting for a warmer day for graduation, but I can't wait too long.  I've decided to name this last one "Last one out."
