Use green food coloring to tint vanilla frosting. Shape the eggs from Tootsie Fruit Rolls, first softening each in the microwave for about 3 seconds. For the egg spots, warm a fruit roll in a contrasting color, break off pieces and form disks, then press them in place. Place green sprinkles in a small bowl. Working with one cupcake at a time, apply a generous layer of frosting, dip it in the bowl of sprinkles, then press on a toy dinosaur and a candy egg.
