In a pie dish, begin by layering the refried beans in the bottom, smoothing out evenly.
Next, add the guacamole, and smooth that out for the next layer.
For the next layer, take 1 cup of the sour cream, and stir in the taco seasoning. Spread this mixture over the guacamole layer.
Next, layer the salsa.
Top with a layer of the shredded cheese.
Dice the roma tomato, and slice the green onion thinly.
Sprinkle the diced tomato and green onion around the outer edge of the dish.
Add the remaining 1 cup of sour cream to a piping bag, and snip off the very tip.
Draw on your spider web.
For the spiders, divide a black olive in half- each half makes a spider body. Then, slice two halves into 4 slices for the 8 legs. Add as many spiders as you want!
Refrigerate until time to serve.
