Fortnite-Dancing Baldi is a joke character in Abandoned Discovery Island.
He is the same as the normal Baldi from his game. The only difference is that he dances, with only fortnite dances.
He can randomly appear in the office at anytime, which is any night. To survive against him, the player must not move a muscle and watch him dance until it ends. No other suits will come to the office when he is dancing there so you will be safe from another suit killing you.
