It's a hot, sunny day and a party of children from the Sunnysands Summer Camp visit the Mill on the Marsh with their talkative tour leader, Wendy Waffle. She can't stop waffling and boring all the children, who are desperate to go to the beach. Grandpa needs to find a way to speed the tour up, so he shrinks.

Wendy Waffle tells the children that Mr Marjoram the jolly miller used to live at the Mill a long time ago. When one of them suggests the mill might be haunted by him, she gets very excited.

Now Grandpa knows what to do. He enlists the help of Josh, Elsie and a reluctant Jason to create the ghost of Mr Marjoram the jolly miller. The ghost persuades Wendy to take the children to the beach. At last, the kids are happy and everyone is left in peace. Show less
