Also included in that Walmart display of all the Rescue Bots toys, is a minor redeco variant of Bumblebee (car mode), which has the Rescue Bots logo in red on the side of the car (instead of white on top), and the black stripes are slightly different as well.
It looks like the Walmart display had Rescan toys from several waves, as the Hotshot and Wedge are from wave 23, the Jet Blades and Salvage are from wave 21, and Boulder (reissue) is from wave 22, while the minor redeco Bumblebee is included in wave 22 and 23.
