    HOW THE ORANGUTAN BECAME ORANGE
    Once deep in the jungle a long time ago there where orangutans. They where not the orangutans you know and love to day they where white fur not orange fur. But one day one special orangutan said we stand out to much we can be attacked way to easy. So he set of on a journey to become a different color. He went high and low searching for some way to change his color. Then one day he going threw the Amazon and something caught his eye it was something orange. He thought well I’m hungry might as well stop and eat. As he was eating he spilled some of the fruits juice on him he said wait. He look garb more orange fruit and squeezed the juice on him self and before you know it he was orange. He went back home and said look every body and they looked and said who are you he said I’m King James. They all said the one that wanted to change its color he said yup they said wow it worked. Then he told them how to change there color they all did and that is how the orangutan got its orange color.
