Just after the sky began to darken they stopped for camp at the destroyed farm house, soon after Gandalf left in a huff he approached his one with the information that he had been checking the perimeter and come across three trolls that seem to have stolen some of our ponies and were preparing to cook them, gloin, Dwalin, Thorin and balin followed bilbo quietly to where they could observe the trolls so they could all plan how to get their ponies back.
Bilbo was thinking about poisonous plants that could be used to poison their soup, collecting a few and cutting them up to release the toxin quicker, bilbo tins the mixture up pockets it and a rock then climbs the tree directly above their camp (all the while the dwarves are still arguing about what they should do) sitting above the pot takes the rock and lobs it to the far right of the camp, all three lumber off in that direction to see what made the noise, bilbo takes the tin out and empties it into the pot getting all the mixture in, soon he rejoins the dwarves who were watching in shock from wen the noise of the rock had sounded from the opposite side of the clearing to which they where hiding.
When bilbo returned to thorin's side he was grabbed and held close by his one, they all watched as the trolls returned and sat to try the soup, "oh that is beautiful" said bert, "mmm quite tasty" stated tom, "eeeew no it's not" says bill swallowing anyway, soon bert was feeling dizzy he stood up just to fall over dead, face first into the ground, followed shortly by the other two, all the dwarrows turned to stare open mouthed at bilbo who just shrugged and said "there must be a troll hoard nearby, they seem at home here."
"There is, over there" said Gandalf pointing in the direction of the cave, Gandalf had returned just in time to see the last of the trolls fall, realising bilbo was the reason they had died but not knowing how made him curious, again, something was a little strange about their hobbit.
