Fortnite’s season six update is now live and among the new gameplay elements introduced are invisibility power-ups, puppies that ride on your back and … boob physics?

First spotted by Twitch streamer Agony, the new Calamity cowgirl skin’s breasts jiggle when she performs the “Jubilation” emote. Once word reached developer Epic Games, the studio quickly acknowledged that the exaggerated physics were “unintentional” and that steps are being taken to remove them from the game.

“This is unintended, embarrassing, and it was careless for us to let this ship,” said an Epic Games spokesperson. “We are working now to fix this as soon as possible.”

Kotaku reports that when asked how something like this could have been unintentionally programmed into a massively popular game such as Fortnite, the spokesperson had no further comment. Perhaps an Epic animator spent a little too much time playing Dead or Alive: Xtreme Beach Volleyball?
