The walls would tremble. The dishes would break. Oh, what a terrible mess we would make! If all the animals came inside, bears would run down the stairs, kangaroos would bounce on the couch, and hippos would play hide-and-seek through the halls! Join one family's wild romp as animals of all shapes and sizes burst through the front door and make themselves right at home. Extraordinary collage artwork from beloved illustrator Marc Brown (Arthur series) pairs with Eric Pinder's hilarious rhyming verse to make this the perfect book to read aloud again and again.
