The energy comes from your hand twisting probably a crank that creates a potential energy in a spring inside. The spring slowly unwinds, releasing its potential energy and putting it into the walking motion.

Ultimately it all ends up as heat. The main source of heat is friction of the moving parts on each other. The movement of air, and the sound it makes also turn into low grade heat when everything settles down.

heat from the air resistance. heat from the rolling resistance (wheels). heat in the axle and bearings. Its kinetic energy also moves the air and is lessened by friction
