Astromech Droid BB-8 was released individually boxed together with Rey
Unlike the 3 3/4 inch version of BB-8 - this version is all the way round - which makes it tricky to display (you'll likely have to lean it against something so that BB-8 doesn't fall over to the side)
There is no magnet inside the body and BB-8 can't be rolled around (the head gets in the way)
BB-8's antennas are not removable
The head can be turned 360 degrees
The head is attached to the body via a plastic stick which allows BB-8's head to be moved into any direction (in addition to the possible 360 degree motion)
Rey is a resilient survivor, a scavenger toughened by a lifetime of dealing with the cutthroats of the harsh desert world of Jakku.
