The Blobfish Book by Jessica Olien
With The Blobfish Book, Olien has a story within a story, meta kind of thing going on. Blobfish, seen initially as a quasi-cute cartoony character, is about to read The Deep Sea Book, which he takes a red crayon to, making it his own.

The twist comes when the enthusiastic, slightly goofy Blobfish finally gets to the page displaying his species and is deeply saddened to learn that the blobfish was once voted the world's ugliest animal. He burst into tears, but his fellow deep sea creatures come to his side and draw up a final page for the book, showing the world that blobfish are in fact cute, friendly and fascinating. The Blobfish Book ends with a two page spread that gives readers more facts about the cast of characters and the environment that they live in.
The Blobfish Book is a good way to introduce readers to this curious creature. But, as a fan of the fish itself, I have no doubt that there are lots more creative possibilities for blobfish in picture books and am sure they are already being written and illustrated...
