I'd take a talking mouse from Narnia! He'd be my friend, and unless authorities found out about my giant talking mouse, or a giant cat came along, he'd always be mine.

Only one thing I could think of, before even coming into this thread. I thought of Digory in The Magician's Nephew- and in his sick mother. I would want an apple.

Sure it wouldn't heal the same, but it would bring about a tree that will give the best apples ever. And on an non-windy day it will just sway with the wind of Narnia very mysteriously.

^ Yes, and when it fell over, you could make a wardrobe...

Oh my gosh, that is so cute!

I would have thedwarves craft me an amulet or a knife and bring it back into our world, so I could always remember my adventures

A talking girl mouse to be my best friend!

Either that, or one of the magic books from Coriakin's house.

Or one of the pretty dresses. Or jewelry- I do not wear jewelry often, but I can imagine Narnian jewelry being beautiful and comfortable.

Lucy's cordial

I really like the apple idea. I like apples and to have something that would cure my chronic allergies would be pure awesome.

EDIT: Oh, I forgot to add! I could make really healthy apple pies and caramel apples!

I would definitely take the Lucy's cordial. Why? Well, of course these days, many kinds of diseases or other kinds of things that hurt the body, it will help me feel better without experiencing surgery or confining in the hospital. Plus, it will decrease my financial problems, LOL.

^ Thats a good idea.
I want to take Aslan! Oh well, I know he's already here.
