I want to introduce you to a friend of mine:
Trevor the toad was originally the familiar of Neville Longbottom (did I mention before, my Potter fan-dom?!?) This one belongs to a seventeen year old English boy who is also a HP afficionado.
I got my Pottermore advance access email today. V. excited indeed....
(Due to massive demand, you might find the Pottermore website inaccessible at the current time)
