Toft is a small boy with big eyes and messy hair. He is shy and quiet, and sometimes feels lonely and out of place. Toft lives alone under the tarpaulin of Hemulen’s boat, often telling himself stories about Moominvalley. One autumn, he decides to visit Moominvalley, but all the Moomintroll’s have left and nobody knows whether or not they will return. In the house, Toft finds an old book with long words, of which he doesn’t understand much. He believes it to be a story and, with the help of his imagination, he creates a creature that turns out to be big and aggressive.

Toft is the only one who remains in the Moominhouse to greet the Moomins when they return, if they return.
