The dwarfs are sending Bilbo to find a light to see if there is lodging.
Second dinner time
Bilbo reaches the light and discovers that the light was fire and the things around it were trolls so he decides to take a wallet form one of the trolls pockets. (But he gets caught)
He’s got a trick up his sleeve
When Bilbo was trying to steal the wallet from the troll he got caught and he was in trouble.
Time to turn to stone
The Dwarves got worried and come and try to rescue Bilbo but little do they know that there are trolls there and trolls like eating dwarfs. So the trolls put the dwarfs in a sack and start to think about how they are going to eat the dawarfs.
Gandalf magically appears out of the blue and start to make the trolls hear voices that sounds like the there own to make them continuously argue.
Dwarfs are in here btw
The Trolls argue till dawn and they cannot be seen by the light or else they will turn to stone and that was Gandalfs plan all alone to make them argue till morning so the will turn to stone and the dwarfs won’t get eaten. ( his plan worked)
