TO MAKE THE GUACAMOLE:
Peel, remove the pit/stone and scoop out avocados into a bowl.
Add the onions, chopped chilies, grated garlic and lime juice and mash along with avocado with a fork or spoon to a fairly smooth mixture.

TO MAKE THE SPIDER WEB:
Fill a squeeze bottle or even a Ziploc bag with the sour cream. Snip of off a small portion on bottom corner to allow the cream to flow smoothly.
Spoon the prepared guacamole into a flat bowl and smoothen the top with an offset spatula or spoon.
Pipe concentric circles of the sour cream over the smoothened guacamole, starting from the center.
Using a toothpick or even a dry spaghetti, pull line starting from the center circle to the edge to form the spider web like design

TO MAKE THE OLIVE SPIDER:
Slice one olive into two long halves.
Use one of the halves for the body of the spider.
Slice the remaining 1 ½ olives with a sharp knife to form the legs.
Gently, using a tweezer, place the body and legs of the spider over the guacamole, to form the shape of a spider! You can place it anywhere you want.

TO MAKE THE AVOCADO SKULL:
Using a sharp knife, make two eyes of the skull, coring into the avocado until you reach the center seed/pit.
For the nose, make an inverted heart shape.
Discard the skin and pulp.
For the mouth, cut a long rectangle; just the skin, and make teeth designs using a sharp knife or toothpick on the exposed avocado flesh.

TO SERVE THE HALLOWEEN SPIDER WEB GUACAMOLE:
Place the bowl in the center of a large serving plate.
Arrange the tortilla chips around the spider web bowl.
Place the avocado skull wherever you please and serve immediately!
Happy Halloween!
