Can you find the jertain in the curtain?
This book is illustrated in classic Seuss style and is replete with imaginary beings and elaborate linguistic fun. Note that this book is not a traditional "story" in the sense of The Cat in the Hat or The Butter Battle. Rather, this book is more like Mr Brown Can Moo! Can you?, Hop on Pop, the Shape of Me, and the Foot Book in that it lists stuff that it is pure fodder for the imagination, without the plot.
There's a Findow in my window!
Published in 1974 by Random House Books for Young Readers. An audiocassette version also exists, as does an adapted "board book" suitable for babies.
