Tone and mood of "Earth on Turtle's Back"

I think that the tone of this story is how the earth was created on the turtles back, and that the mood is how the animals and the human were able to work together. The expository is how it all started from the dream she had. She told it to her husband the chief, and he said that it was a strong dream that they had to do something about it. He had the workers try to pull out the tree but they weren't able to so he did it himself. The lady was peeking down from the top of the branches, and as fell into the whole of water she was only able to grab some seeds. There every animal tried to help her by diving deep into the water to get a piece of the earth for her to live and be safe. Out of all of them the muskrat was the only one that sacrificed the most and achieved it. Then the turtle volunteered to grow earth on its back, there the lady was able to plant the seeds that she grabbed. Right then earth was able to grow, making it a safe environment for her.
