Süsü soon teams up with a wandering prince looking for adventure. He learns about the rules of chivalry and manages to scare half the kingdom while doing it. Then the two travelers come up with a plan: Süsü will pretend to fight the prince, win, and then he will get half the kingdom and the princess' hand in marriage, finding a new home.
The plan doesn't exactly work out: Süsü turns out to be too soft-hearted to hurt or scare anyone, and their secret is outed on the battlefield. In the end, however, things turn out well: Prince and princess fall in love and become king and queen (the old king is happy to retire), they have a little boy who becomes best friends with Süsü, and Süsü becomes the official dragon of the kingdom.
Süsü and the royal family go on to many adventures. At some point, Süsü and the prince save the kingdom from a siege from an evil king in quite a heroic way. Eventually, Süsü gets news that his grandfather arranged for a marriage for him with a lady dragon. After constructing a very elaborate all-kingdom plan to get Süsü out of the wedding, the lady dragon shows up and turns out to be quite lovely and kind. Finally, Süsü gets his own home and his own family, right next door to the human kingdom.
Süsü was the first non-picture book I ever read as a kid, so it holds a special place in my heart. It is a lovely children's story that teaches values like kindness, friendship, bravery, and finding pleasure in the small things in life.
