Jimmy McGee is a tiny leprechaun-like man who thinks of himself as nothing more than a plumber, even if he does do his job very quickly thanks to a certain magic he possesses called zoomie-zoomies. But Jimmy's life of turning on water and fixing dripping faucets is disrupted when he rescues Amy's doll, Little Lydia, from a monstrous wave that sweeps her off the beach. Jimmy keeps Little Lydia safe under his stovepipe hat, right on top of his magic box, where he keeps bolts of thunder and lightning--which causes Little Lydia to become electrified, out-of-control, be-bop doll with the zoomie-zoomies. Can Jimmy find a way to restore Little Lydia to her original state as a "do-nothing doll" before he returns her to her rightful owner?
