Sparky Robot is a wind-up found usually in silver colour and sports a boxy head,sparkling eyes/mouth,and an on/off switch round head antenna.
Sparky is probably the most affordable of the early primitive style bots,when found in good,loose condition..
Sparky's box is often seen in various auctions and it escalates the toy's value, especially found in mint original condition.
