The King's Lost Things are a collection of ten items that are used to identify the new King of the Wilderwest, the heir to Grimbeard the Ghastly. These items were meant to teach a King-to-be important lessons about life and ruling. They were hidden behind formidable dragons, trusted people, and complex puzzles by Grimbeard himself. Valhallarama, mother of Hiccup, often goes on quests to retrieve these items. When she discovered that her son Hiccup had found eight of them, she realized he was the true heir to the kingdom.
