Mix a few drops of orange food coloring into the prepared filling until you reach the desired pumpkin color.

Pipe or spoon the filling into the egg whites, creating a rounded mound. Use a toothpick or the edge of a small knife to make several shallow lines in the filling to resemble the ridges of a pumpkin.

Cut the celery into small pieces and insert one into the top of each pumpkin for the stem. Sprinkle lightly with smoked paprika.

Pipe or spoon the classic filling into the egg whites and sprinkle lightly with smoked paprika.

Cut the black olives to create the spiders. Use a larger piece of olive for the body and cut additional olives into thin strips for the legs.

Arrange the olive pieces over the filling to create a spider on each egg.

For this variation, use the avocado filling instead of the classic filling.

Mash the cooked egg yolks with the avocado, lime juice, cilantro, garlic powder, salt, and black pepper until creamy.

Spoon or pipe the avocado filling into the egg whites.

Cut black olives to create the spider bodies and thin legs. Arrange the olives over the avocado filling and sprinkle with black and white sesame seeds, if desired.

Prepare the avocado filling and spoon or pipe it into the center of the egg whites.

Place a black olive slice in the center of each egg to create the pupil. Add a small dot of ketchup to the center of each olive.

Combine the mayonnaise with enough of the remaining ketchup to create a pale pinkish-red color. Use a toothpick to draw thin lines over the egg whites to resemble bloodshot veins.

Pipe or spoon the classic filling into the egg whites and sprinkle lightly with smoked paprika.

Cut the black olives into pieces to create the bat bodies, pointed ears, and curved wings.

Place an olive body in the center of the filling. Arrange two small pointed pieces at the top for ears and curved olive pieces along the sides for wings.

Add two tiny dots of yellow mustard for the eyes.

Mash the 2 yolks with 1 tablespoon plus 1 teaspoon mayonnaise, 1/3 teaspoon mustard, 1/3 teaspoon vinegar, salt, and black pepper.

Place the silicone molds in the freezer until the filling is firm enough to hold its shape.

Meanwhile, mix orange food coloring into the regular deviled egg filling. Pipe or spoon the orange filling into the egg whites.

Carefully push the hardened filling skulls out of the silicone molds. Place one skull over each egg and gently press it into the orange filling.

Sprinkle lightly with smoked paprika and add fresh parsley around the skulls, if desired.
