Write a method that determines your "trouble level" based on the types of creatures that are surrounding you. Spiders are a little scary so they add 2 to your trouble level. Snakes are more scary so they add 4. Gators are the scariest with their big jaws full of teeth and their swishy tails, so they add 7 to your trouble level. Of course if ALL of these creatures are surrounding you, your trouble level doubles! Look at the test data for examples.
