for The Patterson Puppies and the Rainy Day by Leslie Patricelli
It's a rainy day and the Patterson puppies have run out of things to do. Then Andy spills water on the rug and Penelope has an idea - indoor beach party! The naughty pups spill lots more water, an ocean appears, and soon the surfing, diving and sandcastle-making are in full swing. Until Mum and Dad appear!
