This kit turns into a fabulous mechanical model. When the handle is turned the children trot in a never-ending stream from the bus, to meet their fate between the snapping jaws of the crocodile. The model is approx 40 cm long, 17cm wilde and 17 cm high, and represents very good value at only £18.00! The instructions are very clear with over 50 diagrams, but this model isn'tsuitable for younger children as a fair degree of patience (and a sharp craft knife) is needed to build it.
