Ratnip goes sailing through the city streets after a rainstorm in the seventh book of the chapter book series from the author of Good Dog.
It's raining, it's pouring, and the city rat is...sailing! But a little rain won't stop Ratnip from treasure hunting around the City. Ratnip builds himself a pizza pirate ship and takes to the soggy streets on an adventure--meeting some unexpected underwater creatures along the way.
