Prepare all ingredients. Chop tomatoes and green onions, then slice black olives, reserving some for decoration.

In a mixing bowl, combine sour cream with taco seasoning, stirring well until fully blended.

Layer the ingredients in clear serving cups: start with refried beans, then guacamole, and top with the sour cream mixture.

Add toppings: sprinkle sliced olives, followed by diced tomatoes and a generous handful of shredded cheese.

Decorate with a spider web design using remaining sour cream piped from a sandwich bag.

Create spider decorations using whole olives for bodies and sliced olives for legs.

Serve immediately with mini tortilla chips for dipping.
