This book is definately not for everybody. The story features the Gibbon who is a very minor character in the Marvel U that ends up in a parallel world where every hero is a monkey.
Throughout the story he runs into the world's Avengers and other heros and villains.
This issue has a light of monkey fun puns in it, with of cource a refernence to "flying feces".
Even with it's silly premise, this book has its darker side, downright creepy in fact.
