Mr. Bowles was injured by some creature! You need to help him quickly!

You need to:
  1. Read though the biographies of the different creatures/monsters and find out which one hurt him. 
  2. You have to use reasoning to figure out which creature/monster attacked him. 
  3. You can ask Mr. Bowles yes/no questions about what happened, but you can't ask him which creature it was. For example you CAN ask: "was the creature blue?" but you CANNOT ask: "was it the dragon?"
  4. Try to figure out as a team which creature/monster attacked Mr. Bowles. You have 20 minutes to come up with your best guess! Good luck!
