Pluï is a charming bath toy that playfully teaches children some basic physical principles. Immerse it in water to fill up and then let it rain. The magic lies in the way you can stop the rain simply by closing the hole on top with a finger. Pluï gently introduces babies and toddlers to water while stimulating their imagination and senses. It is also a great toy for children with autism to use for imaginative water play that also provides sensory input.
