In the Hanna-Barbera cartoon version of "The Clockwork Smurf", Handy makes Clockwork to make the Smurfs' lives easier by doing all their work. Clockwork starts off well at first, but then malfunctions thanks to Brainy's ignorant tinkering with his works, causing him to wreck much unintentional havoc. This leads Handy to reluctantly decide, under pressure from the other Smurfs, to deactivate Clockwork and then dump him in the woods. Clockwork revives however, and ends up rallying to the side of Gerard, a boy prince who is the rightful king of his country, but is now imprisoned by his evil aunt Lady Imperia who is ruling instead (she is the villain in this version instead of Gargamel, who doesn't appear). Eventually the Smurfs get involved as well, with Papa Smurf casting a spell of invisibility over himself, Handy and the other Smurfs so that they can help Gerard and Clockwork unseen. In the end, Gerard gets his kingdom back and adopts Clockwork as his friend and advisor, while Handy, pleased that his creation has proven to be useful after all, returns home with the other Smurfs. This adaption also was made and released seasons before "The Smurflings" and "Sassette".
