Okay so whoever solves the riddle and has the answer confirmed by the poster, gets to post a new riddle and the cycle repeats. I'll start. What goes up a chimney down, but won't go down a chimney up?
Ahhhhh the pressure! Ok here goes This thing all things devours: Birds, beasts, trees, flowers; Gnaws iron, bites steel; Grinds hard stones to meal; Slays king, ruins town, And beats high mountain down.
I think that's time.. I recognize the riddle as one told by Gollum in The Hobbit, chapter 5 Riddles In The Dark.
Alright, well I'm not very good at making up riddles but I did my best.. Also I find creepy riddles to be the very best.. So.. Here goes: Our guests howl that we're evil, when they notice their place in the meal. But it's no big deal why; We're just one happy tribe, And we get really fed up with people. What are we?
