Jiggly Hand is a secret boss in Super Smash World. It is a bizarre fusion between Master Hand and Custard. It can be fought as a secret final boss of Master Hand, when Custard's Cute Charm is activated on Master Hand ten times. After being effected by Cute Charm enough, he will kidnap Custard and bring her across every area in the game, while you follow him in the Comet Observatory. Finally, he will come back to the Master Fortress and fuse with her, creating Jiggly Hand. The battle with Jiggly Hand is somewhat underwhelming, and instead of trying to kill you, their goal is just to put you all asleep. Their Attribute is Master. They are also a playable character through the Boss Pack DLC.
