These little snorters are the first enemies that you will encounter in the game. They run around snorting, and if they see you they'll run faster towards you. They're not much of a threat.
Bear
There are Gold Bears and Blue Bears. Gold Bears are stronger, and move faster than Blue Bears. Watch out for the swipe of their bear claw.
Lizard
The lizards just walk around. They are very easy to kill. Don't think that this'll be the last time you see them though! They'll be back in later chapters as stronger, Red Lizards.
Skeleton
These fellas just walk around the place. When you hit them they fall into a pile on the ground, and stop moving. Be careful because they can still hurt you in this state if you touch them. After a moment, they rise again to walk around.
Snowman
Snowmen walk around slowly, and take a few shots to kill.
