A mystery box is a box that was introduced in the third bonus level, Candy. When collected, it gives one of the bonuses listed below:
- A crown. Note that if it already given one, the one might be given again, but has no effects.
- A Ball.
- A Shield.This prevents the player from failing the level from a crash. However, the player may get an extra Shield if they are already using one, but that Shield will have no effect.
- Every time a level is played, Mystery boxes appear in fixed random locations.
