A bear and a tiger prayed to Hwanung, and told him that they wished to become humans. Hwanung, upon hearing their wishes, asked the bear and the tiger to avoid sunlight for 100 days and only eat garlic and mugwort. The bear and the tiger quickly agreed, and retreated to a nearby cave.
In the beginning, the tiger and the bear did quite well. However, after 21 days, the tiger could not endure the situation any longer and left the cave. The bear, determined to become a human, stayed and fulfilled Hwanung’s request. Hwanung, of course, kept his promise and turned the bear into a human. The bear, finally part of humanity, took the name of Ungnyeo (웅녀, Bear Woman).
