The four first olives make eight bodies, while the remaining olives supply the curved leg strips. Divide those strips into eight groups of eight on a clean small plate. Doing the counting before the bagels bake makes the final decoration quick and keeps the warm pizzas from waiting while you discover the last spider has no legs.
Keep the brief first toast, then add the measured sauce and evenly divided mozzarella. After baking and the short stand, arrange the olive bodies and legs on top. These are eight bagel halves rather than eight full-size pizzas, so use their stated yield when planning a snack or a larger meal. Move them with a suitable turner to a clean serving plate.
Timing and servings are estimates. Equipment, ingredients and portion sizes affect the result.
