frogs and ?

The froglet is now essentially a frog as he hardly has much of a tail left and is spending most of his time out of the water.  So I put him in a cup and took him back to Prado, to the same pond he came from.  It took him a minute, but once he figured out where he was, he swam away quite happily.  I hope he doesn't get eaten by any of the birds!

The unknown amphibian's rear legs are growing and have knees now, so he flexes them away from his body often.  Still don't have any idea what he is!
