Robots and cars have always fascinated the kids. Well, how about a robot which can turn into a car vice versa? Yes! That's what the Stem-former is. This latest offering from Smartivity mixes the thrill of a Rover with the excitement of a Bot, all wrapped in a package of concepts such as projectile, elasticity, wind-up mechanism, and gear mechanism. Reuse the box to enjoy multiple gameplays like throwing the pellets at the target area or transform the Bot into a Rover and try to tumble the box. The gameplay is as vivid as you imagination can get. Make this toy truly yours by customising it with your markers and colours.
