Dice

Dice are a kind of item that can be destroyed. They first appear in theme 3-9, then appear onward. It is a standard six-dotted cube die. The dots on the die are essentially its "health bar". When they take damage, they lose dot(s). The more damage dealt to the die takes away more dots. Once they lose all the dots, they are destroyed. 500 points are awarded when it is destroyed.
