Mix the cheese base

• In a mixing bowl, combine the cream cheese, cheddar, mozzarella and sour cream until smooth.
• Season with the garlic powder, onion powder, paprika, Worcestershire sauce, salt and pepper and mix well.

Chill the mixture

• Cover the bowl and refrigerate until the mixture is firm enough to shape.

Shape the skull

• Scoop the chilled mixture out and form a rounded skull shape with a narrower jaw section.
• Use your fingers to press in eye sockets, a nose cavity and a mouth line.
• Smooth the surface with a spatula or damp fingers.

Coat and decorate

• Press the chopped pecans over the surface of the skull, leaving the eye sockets and mouth area clear.
• Place the sliced black olives in the eye sockets and nose cavity.
• Arrange the slivered almonds along the mouth line as teeth.

Chill and serve

• Refrigerate the skull until ready to serve so it holds its shape.
• Serve with crackers.
