Squid and his friends can't find books about slimy characters like them, so Squid writes a book about slimy superheroes.

Squid searches the library for books with characters like him. He reads about furry creatures, feathery creatures, and farmyard creatures, but can't find any books with slimy heroes. His friends Slug, Newt, and Hagfish have the same problem, so Squid decides to write a slimy superhero story, one in which his friends can see themselves. In this tale about representation, equality, and diversity, children will learn about some of Earth's fascinating lesser-known creatures, which are boldly depicted in the engaging and humourous illustrations.
