The Queen Bee will be a new booster accessible near the bottom of the level (where all the lollipops are). The Queen Bee will fly onto the screen and remove candies off the board which will make loads of colour bombs, striped and wrapped candies etc.
I dont know if honey is in Candy Crush Saga but if it isn't then maybe make honey in levels. If this does get created, the Queen Bee can change into the Honey Bee (only on levels with honey) and help remove honey off the board.
