Two of them.

We were traveling in northern MN on a moving house. The house had no walls or ceiling. We stopped in the middle of the woods by Brainerd in order to drop my Grandmother off, and all of the sudden there was a possum. At first the possum was very nice and curious, lots of cuddling. Then it turned on us because I kept pushing it off my shoulders. It started moving faster and jumping at us. I found a juggling club, and I used it as a weapon to defend everyone from the little monster. I woke up just as someone yelled "There's two of them!".
