Combine softened cream cheese, sour cream, and taco seasoning in a bowl, then spread the mixture onto a serving platter.

Create a spider web design on the dip's surface using additional sour cream or a piping bag.

Assemble a "spider" by placing a black olive half for the body and thin olive slices for legs on top of the web.

Preheat the oven to 375°F (190°C), unroll the crescent dough, and separate it into triangles.

Cut each crescent triangle lengthwise into thin strips, then wrap them around the hot dogs to resemble bandages, leaving a small gap for the "face."

Bake for 12-15 minutes until golden brown; after baking, carefully press edible googly eyes into the "face" area before serving with ketchup or mustard.
