Dewey is a raindrop who has nothing more to do than rush around inside his cloud, until one day things change. He finds himself falling towards the earth he has always observed and landing with a splat! After that he begins an amazing journey that opens up a whole new world.As the Dewey series continues the main themes being developed arethat water is essential, it must be cared for and respected, scientific principles can be understood and developed (also moral and emotional conditions)and that no matter what the drops face, they have the hope that they will eventually be back home in the clouds.
