The colourful little bath-ducks are nice by themselves, and squeak when squeezed - but their magic lies in their ability to change colour according to temperature. Each coloured duck changes to a different hue when placed in warm water, and then back to their original colour when they cool down. Definitely a duck with a difference, and bound to cause a stir at bathtime.
