When Fastlegs walks into the stormy night didnt realise that it was stormy for a reason. A tornado had been brewing up, And Fastlegs not noticing walks into the center of it. All of a sudden she flies along with all the wreckage of houses and etc that the tornado was carrying. While rotating in circles with the tornado, her head is smacked against the wreckage causing her to be unconcious.
When the storm end she falls onto a sharp tip of a mountain, causing her to be impaled meaning death. The End =P
