Jen's current size is 40' 4", forgot to mention that.

Jen hesitated for a minute, she almost answered but the woman spoke up.
"Times up Jen, you get both!" She said. "You know, Kyle changed me into this, so I have to follow his dare, for your transformation you'll no longer grow one foot, but five each time the curse activates." Jen gulped, "And since I don't like the pitch of your voice, it'll sound normal for your body's size, and it won't be deafening to you, all the other rules of the original curse apply."
"Okay," Jen said and gasped a little hearing just how loud her voice was at her size now "Um.. Yeah.."
"For your dare, you'll walk to the next curse bearer, your body will know the way just follow it's lead. Have fun."
The woman turned and walked away and Jen stood up, her massive body turned and started walking west, to where she didn't know but she new she'd be much, much larger by the time she got there.
