Jonathan's Funny Funky Fish: A Spot the Differences Book is 32 pages long. The content consists of fourteen pairs of illustrations with five differences between each pair. The book is interactive by nature and the reader is encouraged to find the differences. Solutions are provided in the form of additional illustrations with the differences circled in pencil. Spot the differences books are popular with children between the ages of three and eleven. Jonathan's Funny Funky Fish contains a considerable amount of humor in the form of puns and word play. Children between the ages of seven and eleven appreciate this sort of humor so it is possible the book will appeal to them, as well as to adults who let their own inner children come out to play.
The characters in this book, especially the first three, are original creations. They are drawn using Artrage (TM), an online graphics program.
