Ernest, the Moose Who Doesn't Fit — Catherine Rayner

Ernest is a rather large moose with a rather large problem. He is so big he can't fit inside his book! Luckily, Ernest is also a very determined moose, and he and his little chipmunk friend aren't going to give up easily. With some tape, odd bits of paper, and plenty of enthusiasm, the pair constructs an enormous gatefold page by themselves, and everything fits together in the end.
