a monster that lives deep inside the pipes of your toilet. eats all the poop and instantly grows bigger until the toilet backs up or goes into your average toilet clogging. then before the plunger hits,, it goes deep into the sewer until the left over excrament is removed. dont be alarmed,, they only feed on fecal matter and most every average household posesses a poop monster.
i think we've got ourselves a poop monster in our toilet... time to call the plumber / exterminator.
