Roll out your Fruit Roll-Ups so that they are flat (don't forget to take off the plastic part). Unwrap the Rice Krispie Treats and smoosh them flat onto about half of a Roll-Up. Place several Swedish Fish/Sour Gummy Worms in the center of the Rice Krispie Treats (it's okay if they stick out both ends). Roll the Fruit Roll-Up around the candy until the whole thing looks like a sushi roll. Then, use a sharp knife to cut this long roll into shorter rolls. Et voila!
