"Uberfrog, Uberdragon, Uberbird, Uberbat, and Ubercrab are all part of the "Animal Kingdom Series" by Uberstix and are a perfect example of why the Uberstix build system is so special. The frog leaps, the crab's legs move, the dragon slithers, and the bird and bat's wings flap. The animals are much more than stationary models. As cool as this sounds, it also teaches youngsters about the workings of movable joints and when it's appropriate to engineer creation with moveable, as opposed to non-movable, connections. Kids can build a host of other models with these kits as well, including a minipult that launches small objects. As a bonus, the kits contain a one-hour simple-machines lesson plan."
