Choose a shallow, round serving dish that measures 9 to 10 inches in diameter. Ensure the dish is clean and dry.

Combine 8 ounces of softened cream cheese, 1 cup of sour cream, and 1 tablespoon of taco seasoning in a mixing bowl. Blend until smooth and creamy, then spread evenly across the bottom of your serving dish.

Spoon 1 cup of refried beans over the cream cheese layer, ensuring they cover the entire surface without mixing with the base layer.

Mash 2 ripe avocados with lime juice, 1/4 cup of finely chopped red onion, and optional cilantro. Spread this guacamole over the beans.

Drain excess liquid from 1 cup of salsa, pour it over the guacamole layer, then sprinkle 1 to 1.5 cups of shredded Mexican cheese blend on top.

Thin out 1/2 cup of sour cream with water until it reaches piping consistency. Pipe a spider web design over the cheese layer.

Use a whole black olive as the spider's body and slice additional olives into strips for the legs, arranging them around the body.

Surround the edges of the dip with shredded lettuce, diced tomatoes, and sliced green onions. Cover and refrigerate for at least 30 minutes.
