Grease a muffin tray and set aside. Place popcorn, lollies and peanuts into a large bowl then set aside.
Melt the butter in a large saucepan over medium heat. Stir in marshmallows, red food colouring and yellow food colouring, adjusting colour if needed to get a nice shade of orange. When the marshmallows are completely melted, pour over the popcorn and stir to evenly distribute the lollies, nuts and marshmallow.
Use a greased spoon to fill the muffin cups. Insert a piece of licorice to act as the stem then mold the popcorn around it. Let stand until firm; about 10 to 15 minutes. Remove the pumpkins out by their stems and admire your pumpkin patch!
