The two birds that turned to human had a children. He was named bear.
Bear loved to explore his native lands
One day he decided to go farther than he was allowed and went in a cave.
In the cave he found the bear king. He was scared and didn't know what to do. Weirdly the bear started speaking.
The bear king taught him all about being a bear, how to hunt, move and think like one. Later on bear turned into a cub and started living with the bear.
After many suns of being in the cave bear came out and went to his parents. Unknowingly the parents mistook him for a wild bear and killed him, after slowly closing his eyes he turned to his human self revealing his true human form. After that they protected every animal in their lands putting animals life's first.
