Melt marshmallows, butter, and salt in a large saucepan over low heat, stirring constantly until smooth.

Remove from heat and stir in orange food coloring until evenly tinted.

Add rice cereal and mix until well coated.

Butter hands and shape the mixture into pumpkin-shaped balls.

Place the pumpkin shapes on waxed paper.

Cut Tootsie Rolls in half and press one half into the top of each pumpkin to create a stem.

Using green icing, pipe a leaf next to the Tootsie Roll stem and swirl icing around the pumpkin for a vine.
