At present, Maud had three Devil Fruits stored inside the Shadow Box.
They were the Bomb-Bomb Fruit, the Sound-Sound Fruit, and the String-String Fruit.

Therefore, since the Sound-Sound Fruit still lacked a successor, the idea of combining its abilities with the Empty Shells of Sky Island had to be put on hold for the time being.
Maud shook his head slightly and stopped thinking about it.
He spread his black wings, and as they beat, his body passed through layer upon layer of wind and lightning before finally returning safely to Thriller Bark.
