I love the idea of the ducks. I collect any I find for myself and usually bring along about 20 or so each cruise to hide,. I have started buying the tiny ducks because that way I can hide more as they take up less space. I give away as many as I hide. It is a great way to help parents with a screaming toddler. It almost instantly stops the tantrum. I always ask the parents first if I can offer it, and have never had anyone say no
