Boneless Beyond bendy.
Can be bought from Cash Shop with 500 V-Bucks.
The Boneless is the name of one of the rare emote animations for the game Fortnite Battle Royale. Emotes are gestures and animations that can be activated anytime during the game. However, emotes do not provide any benefits or other functions.
The Boneless Emote is a dance animation that looks rather silly as the player bends his/her parts in a silly way.
