Open cans of cinnamon rolls. Unroll the end of the cinnamon roll about an inch and half or so. Bend it over the top of itself and gently pinch it together, right at the top of the round forming a stem for the pumpkin. Place on a baking sheet sprayed with non-stick cooking spray.
Bake cinnamon rolls for 20 to 22 minutes or according to package directions. While the cinnamon rolls are baking, remove about 1 1/2 tablespoons of frosting from the included container. Add the green food coloring and stir. Use this for the stem end. Add the orange food coloring to the remaining icing and stir well. Use this for the pumpkin part.
