a nice pickle they were all in now : all neatly tied up in sacks , with three angry trolls ( and two with burns and bashes to remember ) sitting by them , arguing whether they should roast them slowly , or mince them fine and boil them , or just sit on them one by one and squash them into jelly : and bilbo up in a bush , with his clothes and his skin torn , not daring to move for fear they should hear him .
