Happy Home

"Welcome to our happy home,/ won't you step inside?" invites this house-shaped board book, which can be fully opened so that the front and back covers touch, creating a 360-degree pop-up panorama with four scenes. Readers can interact with various animals that appear throughout: in the kitchen, a tab makes a gray cat leap up from a chair, spilling milk onto the table, and a wheel helps a goldfish swim in its bowl. Outside, a rabbit winds along a path, and a frog is concealed beneath a lily pad. It's a cheerful domestic tableau, and the interactive elements should prove plenty diverting for beginning readers.
