Hairy Otter and the Philosopher's Loan

Hairy Otter knows he's different, (Snack, the snake, speaking was a bit of a giveaway) but he doesn't know everything until the bear-man. Now he's at Logforts Dam of Mustelidae and Magic, brutal at Quidditch and about to battle a librarian-squirrel. The Reason: HAIRY OTTER IS AN ANIMAGUS…and a wizard, but that's been done…The Bibliomaniac's idea in their story De-Aged.
