Covered with rotting meat from nearby wildlife, the Troll's lair reeks of death.  If the stench alone wasn't enough to scare off an unfortunate travelers who stumbled upon it, the bones of unlucky spelunkers would be.  The Troll places his spoils near the numerous stalagmites on the damp cave wall, his red eyes patiently scanning the dark cave interior for anything that may disturb his isolation.
The Troll's Lair, Cave
a turtle can't escape fast enough to avoid being eaten
the troll
I am the troll who patrols my territory, on the lookout for weary travelers. My appetite for mammals and trinkets is voracious. I am foul smelling and large, but surprisingly agile.
Growl... what is there to feast on for me? Look over there! There's some rotting meat on that carcas, but wait for me I'm just a little slow! Oh no, you look mighty tasty little turtle. I might like me some turtle soup! Really Troll? Could this wait until later I'm just super tired and need a little nap... hahaha.... No me thinks i would like some turtle soup... so look out turtle, because you are mine! Look, here, doesn't this look way more tasty than me, a boring old turtle? How would you even break through this super hard shell I've got here? If you have a nice trinket for me, I might reconsider. Your life for a trinket! But I have nothing on me... What about this dim lamp here? That's a pretty cool lamp if you ask me! No, a trinket for your life! If no trinket, you might consider running... as fast as you can little turtle! BUT I'M SO SLOW!!! Guess we'll just have to fight it out Mr Troll. You are not fast enough little turtle! Take that! Oh no, i'm stuck on my back with these tiny legs flailing around. I'm doomed!
