Nan has trouble with molluscs, and Grandad's pacemaker keeps turning the hoover on. Later, Siadwel tears a hole in his balaclava and Nan repairs the hole, but sews it to his head as well.
Siadwel finds out that his tortoise isn't a tortoise and dad's string vest causes trouble. Later on we hear what Gravel got up to behind Rip Van Winkle's winkle van.
In the last of the series, Siadwel gets his only line in the pantomime wrong and goes to a seance. Later, he tries to clean the stain off the stained-glass windows in St. Eeurgh's Church.
