Cook burger patties until they reach desired doneness.

In small bowl, combine mayonnaise and 4 teaspoons ketchup. Spread each bun base with about 1 tablespoon mayo sauce then add two lettuce leaves and cooked burger patty.

Add pickle slice as monster “tongue.” Take each cheese slice and cut triangles into one side to resemble teeth; add to burger then cover with ketchup “blood,” to taste.

Stick olives on toothpicks and add two to each top bun as “eyeballs.”
