The set of interactive building blocks from the Woopie brand is a fascinating journey into the world of mechanics for the youngest. Consisting of colourful gears, the layout with a construction machinery motif allows you to create movable structures. The toy offers two modes of operation: electric power (battery-powered), which sets the mechanism in motion to the accompaniment of cheerful music, and manual mode, in which the child turns the gears on its own using a convenient crank. Large, safe pieces with excavator, dump truck or concrete mixer graphics fit perfectly with little hands, encouraging creative connection and watching as one moved piece drives the next, including the excavator's movable arm.
