Robots and cars have always fascinated kids. Well, how about a robot which can turn into a car vice versa? Yes! That's what Smartivity Stem-former is! A 2-in-1 construction and play experience that will keep your child engaged for hours in physical activity. 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 parts to enjoy multiple gameplays like throwing the pellets at the target area or transform the Bot into a Rover and try to tumble across the box. The gameplay is as vivid as your imagination can get. Make this toy truly yours by customising it with your markers and colours.
