Cinnamon Bear Popcorn

Mix popcorn, marshmallows, walnuts, and cinnamon bears in a large bowl. Set aside. In a good quality (thick bottomed) saucepan, bring sugar, Karo syrup, and butter to a boil over medium-high heat, stirring constantly. Turn heat down to medium and continue stirring and cooking over a slow boil for five minutes. Remove from heat. Add vanilla and red food coloring. Add to popcorn mixture and quickly stir together. The cinnamon bears and marshmallows should slightly melt. Form into popcorn balls if desired. I usually leave it in the bowl as it tends to disappear quickly at my house!
