Preheat the oven to 350 degrees.
Open the crescent dough, and unroll the sheet. Press with your fingers to seal the perforations.
Use a round cookie cutter or glass to cut 8 circles out of the crescent sheet. Place onto a baking sheet.
Spread a spoonful of pizza sauce onto each crescent circle.
Top with cheese.
Bake for 10-12 minutes, or until the cheese is melted, and crescents are golden.
Remove from the oven.
Slice 12 olives in half lengthwise, and another 4 olives in half widthwise.
Slice 8 of the 12 olives that you just sliced lengthwise into 3 strips to make the spider legs.
To make spiders, place one half lengthwise olive for the body, another widthwise olive for the head, and then 3 (or 4) strips onto each side of the body to make the legs.
Complete this step for all of the mini pizzas.
YES, I know spiders have 8 legs, these are tiny pizzas and not real spiders :)
