Spider Deviled Eggs

Everyone will enjoy this creepy snack for Halloween!

6 eggs
1 cup blueberries
2 tablespoons mayonnaise
1 teaspoon yellow mustard
Salt and pepper to taste
Pitted black olives

1. Place eggs and blueberries in a small pot. Cover eggs with water, cover the pot, and bring to boil. Boil eggs for 5 minutes, then turn off heat. Let eggs sit in the blueberry water for 10 more minutes.
2. Remove eggs and place under cold running water for a minute or so to cool them off. Then press a spoon into the shells of the eggs so the entire shell is cracked.
3. Place cracked eggs back into the blueberry water and cool to room temperature. Place the pot in the refrigerator overnight.
4. Peel the eggs and cut in half lengthwise. Scoop out the yolks and place in a small bowl. Arrange the whites on a serving plate. Mash the yolks with a fork, and mix in the mayo, mustard, salt and pepper, until smooth. Spoon yolks back into whites. 
5. Cut the olives in half and cut some of the halves into thin pieces for the spider legs. Place a half olive in the middle of each egg and arrange 8 spider legs around each olive.
