In Snippy and Snappy, we are introduced to brother and sister field mice living with their mother and father in a cozy nook in a hay field. Their father enthralls them with stories about gardens in big fields, houses in big gardens, kitchen cupboards in big houses, and big yellow cheeses in big kitchen cupboards.

One day Snippy and Snappy wander away from home while playing with their mother's yarn ball. Their journey takes them to a large house full of mysterious things, including cupboards full of wonderful-smelling cheese. Just as Snappy begins to nibble at a piece of cheese in a mousetrap, their father jumps down to rescue them and lead them safely back home.
