Splish-Splashy Day is a 1989 Sesame Street storybook. It's a rainy day on Sesame Street, but that doesn't mean you can't have a good time. The Sesame friends are splashing in puddles, listening to the rain pitter-patter and watching the leaves blow around in the wind. In 2016, Random House reissued the book with a new cover and a new title, Splish-Splashy Spring!
