Everything you need to understand or teach The Wind in the Willows by Kenneth Grahame.
The principle characters in the novel, though they all have their faults, are idealized in many ways. Several virtues are epitomized in Mole, Rat, Badger, and Toad, so much so that they become themes. There are numerous examples of hospitality, forgiveness, compassion, generosity, and humility. Even the arrogant Toad is able to humble himself and put aside his conceited ways in the end, having matured though a succession of trying circumstances with the guidance and help of loyal friends.
