Diabolical Cubus Sisters

The Diabolical Cubus Sisters are group of sisters that, appear to be 4 small Hylian children held captive on Ghost Ship. After Link rescued the first sister he recieved the rather tedious task of taking each and every sister back to the first one. Once all four of them are together, they revel themselves to be scrawny Ghost-like creatures and attack Link with lasers and balls of energy on the deck of the Ghost Ship.

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. The battle is similar to the battles between Link and Phantom Ganon.

Their surname appears to be a reference to the evil mythical creatures, the Sucubus-- which resembled women or girls to mislead and betray men.
