 The youngest son found a house in a forest, where an old man greeted him as a king's son, and told him to put his horse in the stable and have something to eat.After the meal, he asked how the man knew he was a king's son, and the man said he knew many things, including what the prince was doing.He told the prince that he had to stay there the night, though many snakes and toads would crawl over him, and if he stirred, he would turn into one himself.
