Focus on making wrapped candies, and ignore the distractions. However, the liquorice locks need to be removed to increase available board space.
When the opportunity arises, use a few horizontal striped candies to the isolated column.
If you combine two wrapped candies in that isolated column, it will detonate all the others, and that will give you the last seven that you need.
The bomb dispenser will drop a maximum of six candy bombs at any one time and each candy bomb detonates after 15 moves, so if you are down to about that many moves anyway, you can pretty much ignore them. On the other hand, you may keep the upmost wrapped candy to stuck the dispenser and prevent bombs from coming out, although you will have to make another wrapped candy for the order.
Despite the rating of earning three stars as very easy, there is a way of earning less than three stars. It is not to activate the wrapped candy directly below the bomb dispenser until the last wrapped candy. However, this will increase the difficulty of meeting the order.
