@Zoofan15 They could have chosen much better HP names imo. Remus, Padfoot, Weasley and Moony are alright, but "Book of Potions", really? And Tilly isn't even a HP name. They have Padfoot and Moony, but what's wrong with Prongs (although I can see why they might not want to use Wormtail)? There are so many characters in the series that I cannot imagine why they would have to resort to "Book of Potions". Sorry for my rant, I am almost as much a HP nerd as I am a zoo nerd!
@Osedax When I looked up Tilly (I hadn’t heard of her either), it came up with this: Tilly Toke
Altina allow people to name their animals for a small donation, so while the names in this instance are confined to a theme, there’s zero cohesion. Personally, I’d have gone with Draco, Lucius, Bellatrix and Narcissa for the two males and two females (I’m a proud Slytherin).
@Zoofan15 Wow, I did not expect you to be a Slytherin (no offence). I'm Hufflepuff.
So Tilly Toke is the one who saved those Muggles from the Common Welsh Green in Ilfracombe (given a brief mention in Fantastic Beasts and Where to Find Them). I never could remember her name.
