Well are we sitting comfortably then let me begin deep in the sewers of LANDEN (london) the sewer creature lurks it stalks a victim by appearing in thier house each night (it gets into the house by climbing through the toilet) and it eventually eats them crawling back into the sewers there have been many sightings of this creature some claim it's tall others say small what it looks like no one i repeat no one (except that one old guy) knows the only evidence of it's existance is one photoghraph. I guess it relates to the contest because sewers are underground.

please please please let that description be good enough i don't want to be disqualified twice.
