The goblins rushed upon the company faster than any of the dwarves could react, pushing them roughly along the rickety wooden walkway as they scrambled to bind their hands with ropes at the same time.

Being much smaller than the dwarves, Bilbo was soon unnoticed by the goblins and so the hobbit ducked down low to the ground and watched the goblins scurry away ahead with the dwarves forced to stumble along with them. Keeping his sword drawn, he took a step to follow the dwarves with the intention of trying to free them, but it was then that another goblin jumped at him from the ceiling, and in the struggle, they both fell off the edge of the walkway and into the chasm below. Luckily, Bilbo landed on a pile of what looked to be some sort of mushroom, so he didn't break or injure anything. Though he wasn't sure how he was going to get back up to the others.
