On the fifteenth of May in the Jungle of Nool, he was taking a nice walk with the sun shining from high in the sky when Horton the elephant heard a unfamiliar sound. So Horton stopped walking, he looked towards the sound. "That's funny, there's no one here.", Horton thought. Then he heard it again just a very faint cry as if a creature is crying. He looked and he looked around, but he could see nothing there. He had to follow the sound of crying and wondered what it would be. He was not sure what it was and he had to find out right away. He sure is curious about the cry. Then when he got there, he was shocked to see a human baby in the jungle.

He was starting to wonder how did a human baby manage to be alone in the jungle of Nool, but he knows that baby needs to have nourishment and soon. Without a mother's care the poor thing will soon die. He also knows that he can't just leave the baby here and the poor little thing will die. Horton will just have to take the little thing and he knows that it's a living thing, no matter what size. He knows the one animal that would help him and it's the sour kangaroo. She will know how to help the poor baby. While he was on his way to see her, he thought of something, he would take care of the baby and raise it as his own. He thought that it was not a bad idea and he would have to give it a try.

While he saw the kangaroo he told her the story on how he found the baby. He was not sure if he would tell her his idea, but the kangaroo said to him, "You must care for the child and raise it as your own." Horton's eyes widen, that was his idea and he agreed. The Sour Kangaroo then told him that there will be a meeting for the girl and she will be known as the Girl of Nool. Horton smiled and named his new daughter Lily.
