Mix milk (as called for on pudding package) with a couple spoonfulls of pumpkin puree - enough to make it a medium orange color.  Stir in spices and pudding mix.  Mix according to directions on the package. 

This is great at a little kids halloween party.  Just divide it into dixie cups and decorate the top with a mallow creme pumpkin.  (Like candy corn.)  Kids love to help make this!
