The figure is called Dwarf Spider Droid, there are 2 versions out, the ones I bougt came in a package with a couple of other humanoid shaped droids, Super Battle Droid and the Security Battle Droid, loved the walker so bought 2 of the packs but alas, I dont recall the actual name of the package. The walker measurements are 4 inches by 4 inches spread for the legs on the ground and 3.5 inches high to the top of the antenna, top of the sphere is 3 inches.
