Get ready for a rainy-day adventure with Duck and Hippo! Duck and Hippo may be completely different, but they are best friends. When playful Duck invites careful Hippo to go for a walk in the rain, they have trouble sharing Duck's umbrella. But Duck and Hippo won't let that stop them. Soon they are puddle-jumping and sailing down the river! Until. WHOOOSH! A terrible wind sends the umbrella flying up, up, up into the air, with one friend holding on. What will Duck and Hippo do now? Jonathan London's charming text and Andrew Joyner's delightful art bring to life two lovable friends in this fun new series.
