Easy ways to level up and kill bosses

From: Lemon

So I know how hard it is to get money, and after 127 levels of playing, I have found that the easiest way is to run around madly killing stuff. The moose just lead to water, the bear climb the mountain and jump off the world, the bull hide behind the fence, and on multiplayer just wait for people to kill it and jump in at the last second and help.
