Slice hard boiled eggs in half and mash yolks using your favorite deviled eggs recipe

Add three or four drops of green food coloring

Spoon half the yolk mixture into a Ziploc bag (or a pastry bag)

Cut off the tip of the bag

Pipe into egg halves by the pair.

Mix three or four blue drops to the remaining yolk mixture.

Spoon into a new Ziploc bag, cut off the tip, and pipe yolk mixture into remaining pairs.

Cut the sides of the black olives so that they're fairly round

Place them in the center of the deviled eggs (to look like pupils).

Pour some paprika onto a plate and wet with enough water to make a paste.

Using a toothpick, lightly draw on a few veins here and there.
