Plumber's Mate. When Old Tom is finishing his bath, his favourite bath toy - a rubber duckie - goes down the plug hole and gets stuck in the house's plumbing. Old Tom tries to retrieve the toy, but ends up soaking Lavinia, who has come for tea. On Lavinia's advice, Angela calls a plumber who, with Old Tom's help, tries to fix the problem. But he, too, accidentally soaks Lavinia. Tired of all the drenching, Lavinia leaves, only to be soaked again when the blocked garden hose explodes, flooding the house - but finally releasing the little rubber duckie.
