"Never smile at a Crocodile"!

Ruby found a new plaything today in my room. I have a wooden crocodile, can't remember where it came from but it's flexible due to, what looks like, a resined string right along it's back.
I've always liked it and now Ruby seems to enjoy playing with it.
I won't sing the song to her, don't want to spoil her opinion of Crocodiles, I suppose I'd better not let her watch Peter Pan when she's older either!
