This is a radio or remote-controlled model.
You can supervise the activities of this little BN-88 figure with the lightsaber control unit! BB-8 will move back and forth, and you can make his head turn, too. The lightsaber also provides some BB-8-appropriate booping and beeping noises, and he can attach to the lightsaber controller so you can keep him out of trouble when you're not playing with him. This fun toy is great for anyone, and all it needs is 2 AAA batteries (not included) to start the magic!
