Diabolical Cubus Sisters

These are a rather annoying group of sisters that, while on the ghost ship look slightly creepy but like-able enough. You recieve the rather tedious task of taking each and every one back to the first sister. It is questionable if you have to do this and my answer is no. So, if you haven't done so already, don;t rescue the sisters. Once all four of them are together, they will turn into scrawny creatures and attack you with lasers and a ball of energy. To defeat them you will have to knock back the ball of energy by doing a spin attack. When they attack, 3 of them will start shooting lasers, which you can dodge quite easily and one of them will not do anything until the others stop. Once the others stop, the inactive Cubus sister will attack with an energy ball and you will have to knock it back or get hurt. Its like a ghostly game of Hot Potato and eventually they will lose.
