Those of you who bought the hit Star Wars BB-8 droid toy, based on the remote-controlled Sphero orb, will get a new experience if you watch The Force Awakens together.

When the film is playing in its vicinity, BB-8 will now listen for cues in the audio that trigger responses — according to the Wall Street Journal, the appearance of Han Solo and Chewbacca elicits wild excitement, villain Kylo Ren makes BB-8 cower, and the droid proudly burbles in reaction to its own performance.
