This cute and endearing animal may seem to be the most adorable monster you'll ever kill... Do not be fooled; it is a highly dangerous killer. The Bipolar Bear changes personalities constantly, directly effecting this beast's fighting capabilities. For example: when it's mad, its attacks become very powerful and are delivered with speeds that greased lightning would envy. When sad, it gets very defensive and extremely hard to kill. When happy, it becomes more agile, treading ground at an unsettling speed. The strength of its emotion dictates how much of a boost it receives. At first glance, heroes see a small, cuddly, furball of happiness. As they get closer to pet it, the monster within unleashes on the unsuspecting hero and he/she must fight to survive. Also, very rarely, these monsters may develop a respect for the hero and may want to become his/her companion. Such heroes are very lucky and should take the utmost care of their new pet.
Accidentally created when a man in Concrete, Washington used a cursed Babylonian coin at a wishing well in a chinese restaurant to wish for a woman that loved him forever. This coin caused all wishes to go bad , and when a girl named Audrey wished for her teddy bear to start talking, it turned true and made the bear bipolar.
<!--That was from the show Supernatural, episode "Wishful Thinking"-->
