01 - In a mixing bowl, combine the refried beans with the taco seasoning until thoroughly blended. Spread this mixture evenly across the bottom of a shallow serving dish.
02 - Carefully add the ingredients in the following order: guacamole, sour cream, drained chunky salsa, shredded cheddar-jack cheese, sliced black olives, and finally the thinly sliced green onions.
03 - Transfer the 1/4 cup of sour cream to a zip-top bag. Snip a small corner and pipe concentric circles onto the surface of the dip. Using a toothpick or skewer, gently drag lines from the center outwards to create a spiderweb effect.
04 - Position the halved black olives around the dip to resemble bats, placing them strategically on the web or around the edges.
05 - Cover the dish and refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled with tortilla chips.
