Minerva’s hand passed over one of those objects, the one with golden wibblers, her eyes closing briefly.
Heh. From Chapter 17:
Oh, the little fiddly things?” said Dumbledore. “They came with the Headmaster’s office and I have absolutely no idea what most of them do. Although this dial with the eight hands counts the number of, let’s call them sneezes, by left-handed witches within the borders of France, you would not believe how much work it took to nail that down. And this one with the golden wibblers is my own invention and Minerva is never, ever going to figure out what it’s doing.”
Heh. From Chapter 17:
What is a wibbler by the way? I google it and all I get doesn’t make sense.
I think it’s a mix of a wobbler and a wibble, the latter mostly in the metasyntactic variable sense :-)
