Watch - Wonky time

When he got to the top, he realized just why Fitzwilliam had been speechless. Above them, filling the sky, still as everything else in the world, were what looked like huge birds. Bigger—and stranger—than any birds Jack had ever seen. They were leathery, not feathered; with huge beaks, and their wings stretched for what looked like fifty feet.

"Wow—lots of birds. Flying north for the summer, you think?" Jack asked.

"Jack," Fitzwilliam answered, "These are pterodactyls. They were largely thought to be a thing of legend, but I have a tutor who claims to have uncovered the bones of just such an animal. He also claims that they went extinct millions of years ago. Jack, this watch—I don't think it's just stopping time ..."

". . . It's making it go all funny," Jack finished for Fitzwilliam. "That certainly explains why Stone-Eyed Sam's kingdom is still intact. And why the Barnacle's skiff was missing and there was a totem pole in its place. The skiff must have been carved from a totem pole, and when I used the watch, it reverted to that state."
