These are so easy and fun that your kids will love them.  The Tang adds a touch of acidity to balance all the sweetness.

Preparation

In a large mixing bowl add the popcorn and walnuts, and toss together.

Melt the butter over medium-low heat, when it is melted, stir in the marshmallows. Stir constantly until they become liquid.  Pour over the porcorn mixture and stir to combine.  Press into a lightly greased baking dish, and allow to cool.

When cool to the touch scoop out about a 1/2 cup of the popcorn mixture and roll into balls.  If it is too sticky you can oil up your hands.  Sprinkle a liberal amount of the Tang onto the pocorn balls until heavily coated and orange.  Decorate with licorice to make eyes, a mouth, or the stem of a pumpkin.
