Another adventure begins for Stella and her brother, Sam, as they explore the wonders of the natural world. A vast luminous sky, the sun, the stars and the rising moon form the backdrop for their nocturnal expedition. As they encounter raccoons, fireflies, tree frogs and bats, Sam wonders if the moon can swim, if the sun wears pajamas or if he can catch shooting stars with his butterfly net. Stella, as always, has an answer for every question.
