The god Michabo was hunting with his pack of trained wolves one day when he saw the strangest sight, the wolves entered a lake and disappeared. He followed them into the water to fetch them and as he did so, the entire world flooded.
Michabo then sent forth a raven to find some soil with which to make a new earth, but the bird returned unsuccessful in its quest.
Then Michabo sent an otter to do the same thing, but again to no avail.
Finally he sent the muskrat and she brought him back enough earth to begin the reconstruction of the world. The trees had lost their branches in the flood, so Michabo shot magic arrows at them that immediately became new branches covered with leaves.
Then Michabo married the muskrat and they became the parents of the human race.
