The cake bomb is first introduced in level 344 and is one of the harder blockers to destroy. This is the only blocker that takes up 4 squares and is a round cake looking blocker. It can take anywhere between 1 and 8 moves to destroy a cake bomb. To destroy a cake bomb, simply destroy adjacent candies and pieces of the cake will break off. Once you destroy the cake, a party popper will appear and it will explode all candies and blockers in the level. This can be a good and bad thing. The problem is that is destroys special candies as well, so if you are trying to save them, it will not help you much.
