Explosive mushrooms are game objects that can’t be matched with and they aren’t affected by gravity. They cannot be removed. Mushrooms come in different colors and have a number on them. When you make matches with the colored pieces in that color anywhere on the level, it will decrease the number written on the Mushroom. When you make enough matches and the number gets to 0, the Mushroom will create a big explosion, destroying colored pieces and obstacles around it.
