Preheat the oven broiler.
Using Halloween cookie cutters, cut each tortilla into festive shapes.
Brush the olive oil on each side of the tortilla cutouts. Place them on a cookie sheet. Place the cookie sheet under the broiler, about 4 inches away from the heat, and cook until it begins to brown.
Flip the tortilla chips over and cook until the tops are lightly browned.
Remove from the oven and lightly sprinkle with salt.
Serve with bat blood (salsa).
