Squish him into jelly
Gothmog had an excellent idea, an idea that would lighten his load and get rid of the Troll at the same time. Peering up the tower the fake eye of Sauron loomed, Gothmog peered at his copilot and began snarling in orcish "go loosen those bolts and let the eye crush this troll if we're lucky it may even roll into the paths of the others!"
As Orcky(for Gothmog still didn't know his name) Climbed the tower gothmog looked ahead at the Troll. "Friend you are about to be destroyed and Im hungry you look like you have a bit of meat on ya'"
The troll just laughed "You little pipsqueak just pay the toll or go back because as I always say a Toll is a toll and a roll is a roll we don't get no toll we don't eat no--" as the troll began to finish his sentence A giant red eye came as a meteorite from the sky landed on the troll the following shockwave was intense but not to bad. the eye slowly rolled into the surrounding trees.
"Well then," Gothmog looked ahead, "To bad the meats all destroyed at any rate we shall stay the course head for the Old road!
SouthWest Barad-Dash rumbled slowly forward..."I feel the need the need for speed!" with that Gothmog grabbed his whip, "Time to 'encourage' the slaves"
