It seems to be a standard that cruise ships fold towels into animal shapes and place on your bed each night. They always have a towel folding class on board (I've never been to one) and sell books on how to fold them into various shapes. Below are the animals we found each night when we returned to our room. I will post another showing a couple of naughty looking towels.
Tuesday night we found the elephant
Wednesday night this cute bunny was stretched out relaxing on my bed
Thursday night was the cobra, although it took us a while to figure out what it was as you will see in my next post
