A diminutive man who lives inside a pumpkin is swept away when his anchor stem breaks, sending his home into the sea and launching a sequence of whimsical episodes. He encounters storms, a whale, strange valleys with peculiar dangers and charms, a palace, capture and rescue, a toothless enemy, and a patient princess. Through mishaps, inventive cooking, clever trickery, and promises kept, he navigates shifting landscapes and social encounters before resolving conflicts with the antagonist and returning joy to others, culminating in a cheerful, neatly tied conclusion.
