The book cover is colored blue. The front cover was not seen. The back cover was just colored blue and was plain. The spine of the book contained the book's title, a symbol of a skull and crossbones and two yellow lines at the bottom of the spine.


Only two pages of the pages were seen, and the following is what was contained in those two pages. (Note: [...] represents text that could not be seen or deduced.)

  • Cleopatra, one character in an Arthur Conan Doyle story; what do these characters have in common? These are fictional characters that have died of venomous bites that could be found within a short internet search. What else do they all have in common? They did not possess this fantastic book on venom and antidotes. Mistake number one. This book is really good you guys. It's questionable whether or not fictional characters created after this book can die of venomous bites. We believe readers would find it unrealistic.

  1. Grab Venomous Creature
  2. Poke Teeth Into the net above the cup
  3. Push down on back of the head
  4. Milk Dat Creature

  6. Use the Anti-Venom
