The famous train, full of history and intrigue, is the perfect setting for a little dinner theatre. But what's real and what's part of the performance becomes a little blurry when Paddington's jar of marmalade sets of a mystery that is not part of the script.

While pretending to be archeologists in the garden with Judy and Jonathan, Paddington buries the Frog of Doom - one of Mrs. Bird's more unusual teapots. Mr. Curry doesn't know it's just a game of make believe, and he's delighted to have himself a dandy new teapot - except when the curse of the Frog of Doom start to come true!
