You get a projectile that you can use once with each present and Mystery Vase you pick/buy. The projectile you get is random. You can then pick a target to shoot at, and based on luck, you either hit or miss the target. A hit will score points for the event.

The odds of hitting or a missing depends on the projectile and target. Example: With the Cabbage that has 70 accuracy, if you pick the Medium Target, it's accuracy is divided by two, because 2 is the difficulty of the target. That means its accuracy is 35, and you have a 35% chance of hitting the target.

Every time you hit a target, you score points for the event. Harder targets are worth more points, but should only be shot at with high-accuracy projectiles.
