Try to keep from getting too excited and then use it very carefully, as it is magical.

WWYDI you were accused by the Narnians of being a traitor?

"Say what?!"

WWYDI a non-Narniac friend of yours managed to get into Narnia, but you couldn't?

"I thought you said Narnia didn't exist..." 🙂

WWYDI you were about to be turned to stone by Jadis?

Scream for Aslan as loud as I could.

WWYDI you were captured by Calormenes and your only means of escape would be to pretend to be loyal to the Calormenes by fighting a Narnian?

Remain captured forever. I would rather die than fight against my own people.

WWYDI you found yourself face-to-face with the Lady of The Green Kirtle?

Probably be entranced.... 😕

WWYDI Tumnus asked you to teach him the geography of our world?

I'd try, but I probably wouldn't do a very good job...I'm not too good at geography.

Scream my head off and run! 😀
WWYDI The ground suddenly sank out under your feet?

Scream, call for Aslan and find something to hold onto to keep from sinking.

WWYDI you came face-to-face with Jadis during the 100 years of winter?

Run OR faint.
Realistically, I'd die.

Walk through it, of course!

Go and explore!
WWYDI A centaur challenged you to a duel?

Um, decline? Or if I accepted, lose!

WWYDI you were cornered by a pack of Wolves?

Wish that the Beast (from Beauty and the Beast) would show up quick and save me! 😆

WWYDI you were suddenly surrounded by fauns?

Be absolutely thrilled!

WWYDI you had a chance to become the most beautiful person in the world, and it wasn't wrong and forbidden for you to do it?
