This is the fifth book in the Flanimals series created by Ricky Gervais in 2004. I must really be out of the imaginary creature loop because I hadn't ever heard of them before. I'm certainly glad to have been made aware of their existence, as this is one excellent pop up book!
The introduction to Flanimals from the author's own website:
"Flanimals were first sighted by Ricky Gervais a long time ago. He drew some rough sketches and made notes about their behavior. Then, Ricky asked his friend Rob Steen to draw them properly, anatomically correct and exactly as they appear in their natural habitat."
Still not sure? Flanimals are a collection of really strange creatures complete with crazy names, weird body structures and odd vulgarities. Translation: exactly the kind of thing that kids live for. They range from a bit icky, like the puddle of pink gooey Splunge, to the downright disgusting sweat glanded Mung Ungler. The pop-ups are fabulous - six really large ones in the center of each page, with pull tabs and smaller paged booklets tucked neatly at the corners of each page. Outstanding!
Both children and grown-ups alike will laugh themselves silly at the comic genius here. And since it's nearly impossible to present photos from a pop up book, enjoy this delightful video from the author himself.
