Squirrel Origin
Long ago when no squirrel roamed the earth, there was a giant tree. Today this tree has come to be known as the Tree of Life. The tree was very lonely, until one day it decided it needed something to keep it occupied. That's when the tree started to mature into an adult, and It started to grow itself some nuts. The tree loved his nuts and played with them whenever he felt lonely. One day the tree woke up to find his nuts had dropped to the ground. He wondered why this had happened to his nuts. He was very sad for the weeks to come until the day he noticed some of his dropped nuts had disappeared from the ground. "Where did they go" he wondered? Then the tree felt a tickle on his backside, when he investigated into what it was he saw a strange creature he had never seen before. This animal was grey and could climb up his trunk like nothing he'd ever seen before. The tree decided to call this strange creature a squirrel because it was the first name that came to his head in his primitive tree language. The squirrels were happy to climb up and down the Tree of Life’s trunk, and they kept the tree happy too.
One day however the tree noticed that the squirrels were collecting his nuts off of the ground. He tried communicating to them to ask why they were collecting his nuts in their cheeks, but with little luck because squirrels don't understand tree speak. The squirrels were collecting his nuts because they believed since they grew from the trees nuts that the unborn squirrel spirits were trapped inside of his still lying acorns. The tree could do nothing about the squirrels collecting, so he decided to not grow new nuts so that there could be no more squirrels to roam around and steal from him. Luckily for the squirrels they found a natural way to replicate their kind and have lived on in this world ever since.
