Zendaya, Bella Thorne and Caroline Sunshine watch as their science project lights up in this new still from Shake It Up.

In the upcoming episode “Heat It Up,” When the heat goes out in Rocky’s (Zendaya) apartment, CeCe (Thorne) invites Rocky and her family to move in with them, but the tight quarters quickly become too close for comfort.

Meanwhile, Ty (Roshon Fegan) and Flynn (Davis Cleveland) build themselves a man cave to get away from it all.

“Heat It Up” premieres Sunday, February 27 @ 8:30PM ET/PT on Disney Channel.
