Idea: Syrup

This is an idea for a new, incredibly difficult blocker. Syrup would spread like chocolate, and can have two layers maximum. One layered Syrup can be cleared like jelly, but if a move is made without destroying a Syrup, the one layered Syrup will gain a layer and will act like Frosting. When two layered Syrup is hit, it will create a small explosion, leaving behind one layered Syrup. Syrup must be cleared very quickly, or it will overtake the board! Also, special candies can spread Syrup.
