Almost comical, this little green amphibian friend leaps with a joyful sense of freedom. Using its hind legs and rubber feet, Happy Hopping Frog jiggles its eyes as a dog would wag its tail acknowledging its love and appreciation to its owner. The tailless, leaping mini solar kit is activated by the power of the suns rays; no batteries required. Happy Hopping Frog is a kit that demonstrates alternative energy principles. No batteries required and only approximately twenty-five parts to assemble. Recommended for ages 9 and up.
