Tumbles the Stairdragon is the moniker earned by an otherwise unremarkable furfag who generated totalulz by trying to become an hero at a furry convention. When his attempt to slash his throat with a thick plastic sunglass lens failed to generate sufficient drama, he flung himself down a steep flight of concrete stairs. Unfortunately for him (and for everyone else), the staircase only had seven stairs. Fortunately for the gene pool, he's a fag and won't be reproducing anyway.
