Stilly River Sage, I can't remember which book, I think it was the second...Hermione finds her teeth are growing because of some potion or spell that backfired on her, and I have a pretty clear memory that she was dismayed because her teeth were already buck and afterwards, they were like a beaver's.

Tell you what, give me a while and I'll track down the exact book and reference. But something like that wouldn't have stuck in my mind for no reason.

Black Walnut, I also was the last one in the theatre and loved the footprints, especially when they became paw prints. Nice to see them having fun with one of the best things in that book (and how it was depicted in the film)-The Map! Though I do wish they had been able to make it clearer that the authors were the group of friends using their animagus names. One of those things you'd only know if you'd read the book.
