Vincent, a mouse who roams the world carrying his house on his back and stopping where he knows he should, offers food and shelter to animals in need. After setting up his house, he invites a weary bullfrog and a hungry cat inside. Each initially declines the offer, saying his house is too small. But after entering, they find that it is bigger than it looks. Others soon join them: deer, hedgehogs, badgers, rabbits, and a fox. Just as they are sitting down to dinner, a large, hungry bear knocks on Vincent's door. Fearful, the other animals urge their host to turn him away, but Vincent opens his home to the gentle bear, and all is well.
