Here Be Monsters! An Adventure Involving Magic, Trolls, and Other Creatures; The Ratbridge Chronicles Volume 1 Chapter 44

The Shaft!

• Grandfather, Willbury, and the others of their group are united with the rest of the captured boxtrolls and crew. Snatcher's goons grab a prisoner to shrink first, and it turns out to be Marjorie.
• Willbury tries to stall for time by getting Snatcher to gloat about his evil plan. Snatcher admits that they're funneling the stolen size into a big friend of theirs, who will soon be unstoppable.
• Snatcher's minions start up the machines, and ominous noises fill the room.
