Exit from fire realm?

Howdy all,

I've successfully collected the first earth power (yeah!) and am looking for the way home (back to town). Clicking my red ruby slippers together while reciting "There's no place like home. There's no place like home." did not have the desired effect.

I'm currently wandering in the are where you use the 3 keys and there's a large bbq (well that what I think it is anyway) in the center of the level.

Don't need extensive details at this point, just a little nudge would be greatly appreciated!
