"Mr Hoppy wished more than ever that he could become a tortoise.... Have you ever wanted to turn into something else? I bet it wasn't a tortoise! This is the story of a very shy man who's in love with a very kind woman and of the small tortoise that brings them together."

This isn't one of Roald Dahl's best, partly because it's so short but also because - having much experience in this matter myself - doesn't really capture the true spirit of owning a tortoise. Probably best for under 5s.
