Mix-Up Pop-Up books display and zany art, amusing pop-ups, and split pages that inspire kids to conjure up their own strange creatures. Each page is split into top and bottom halves so that the top of one animal's head can be matched with the bottom half of another to produce a whimsical creature that never existed, except in kids' imaginations. And when each page is opened to its full width, the pictured animal's mouth pops up and snaps shut in a most horrifying way! The full-color illustrations that fill the two-page spreads will turn children's surprise into squeals of laughter! In Ocean Oddballs you can mix a crab with a penguin, but do you now have a crain or a pengab? Kids can call it whatever they like, then go on to mix and match the other animal faces in this funny book.
