I want to say I'd probably not do it since I don't care and certainly don't want the attention. But I wouldn't know till I was in that situation.
WWYDI you were "uglified"?
Enjoy being able to jump 30 feet in the air and paddle around on the ocean, then when that got old, possibly look for an "unuglifying" spell in Coriakin's book.
WWYDI you were alone on a mountain you'd never been on before, in the middle of the night, and you suddenly heard a voice coming out of the darkness beside you?
Scream. And probably jump and slip.
WWYDI you were stuck behind a couch listening in on a secret meeting?
Try really hard not to breathe.
WWYDI you had to spend all night by yourself at the Tombs?
Wait for a cat to appear. 😆
WWYDI you got to spend an afternoon with Lasaraleen?
Be bored out of my mind after some time, suffocate from her perfumes, go deaf from her talking and giggling my ears off, probably admire her dresses, and wish she'd shut her yap and leave me in peace! 🙄
WWYDI Rabadash made his shark-face at you?
Laugh.
WWYDI if Peter offered to teach you how to use a sword?
Forget my manners. 
WWYDI Corin threatened to knock you down?
Not disagree with him.
WWYDI you found The Wardrobe at an auction?
BUY IT BUY IT!!!!!!!
WWYDI you found Jadis in your closet?
Scream and close the door tightly and call the police. And pray. Hard.
WWYDI you found a lamppost in the woods?
Take a picture and wonder if I was in Narnia.
WWYDI all the satyrs and fauns suddenly started fighting against the other Narnians?
Gather an army of Narnians to fight back.
WWYDI you met a family, with two guys and two girls who just happened to be named Peter, Susan, Edmund and Lucy?
(You mean besides my future one? 😛 )
Freak out and ask if they've ever read the Narnia books.
WWYDI you found yourself in the raid on Miraz's castle in movie!PC?
Smack Peter upside the head. Probably not, actually. But I probably would give him some grief....
WWYDI you fell into a picture not of a ship?
