Oh, for those who haven't read Fantastic Beasts, the pets would be described here:
Crup
Creature alike Jack Russel Terrier with a forked tail. Very anti-muggle and very faithful to owner.
Diricrawl
Better known to muggles as the 'Dodo'. It is able to vanish at will and reapper somewhere else.
Hippogriff
I don't think you need an explanation for this one, do you?
Chimera
A rare Greek monster with a lion's head, a goat's body and a dragon's tail. It is vicious and bloody and extremely dangerous.
Kneazle
An extremely faithful cat-like pet that can bring the owner home if he is lost.
So who will it be?
