Line a half-sheet pan with parchment paper and set aside until ready to use.
Melt the unsalted butter in a large pot set over low heat. Once the butter has melted, add the jumbo extra-large marshmallows. Stir the marshmallows with the melted butter so that they are all well coated. Then, continue stirring occasionally until the marshmallows are melted and the mixture is smooth.
Next, remove the pot from the heat and add the Rice Krispies Shocking Orange Colored Cereal. Then, carefully stir the Rice Krispies into the marshmallow mixture to combine them well.
Put on a pair of vinyl food-grade gloves. Spray the inside of a large ice cream scoop2 and one of your gloved hands with non-stick cooking spray. Rub your hands together so they're both coated with the spray. While the mixture is still warm, use the ice cream scoop to portion out the Rice Krispie mixture.
Then, use your gloved hands to form the Rice Krispie mixture into a ball, pressing the mixture as tight as possible. Then, place it on the prepared sheet pan. Repeat making balls with the remaining mixture.
After you've formed all of the Rice Krispie mixture into balls, cut the Tootsie Rolls in half. Then, place a small amount of the green cookie icing in the center top of one of the balls. This little bit of icing will hold the Tootsie Roll in place.
Immediately place one of the Tootsie Roll halves onto the icing on top of the ball. Then, slightly press the Tootsie Roll into the ball. Pick the ball up in your hands and press it together again, reforming it to make sure it holds its shape.
Use the green cookie icing to draw veins over the tops and slightly down the sides of the Rice Krispie Pumpkins. Allow the cookie icing to harden for four hours. Once dry, transfer the Rice Krispie Pumpkins to an airtight container.
