False it actually modifys something that has been left out of the sentence.
You'll have to be somewhat more specific with regards to what form of transformation you refer to. Shaper shifter, red riding hood and the wolf, multiple personality disorders, serial killer etc...

Explanation:
My uncle told me he had a surprise! It will be
revealed "as soon as" 1 pm.
"Once" I heard about the surprise, I jumped out of bed and got ready for the day.
"Since" I was busy getting ready, I tried to keep guessing what the surprise could be!
We immediately got into the car so we could
arrive at the surprise on time.
We left to drive to the surprise "even though"
we were all packed into the car.
I keep trying to make guesses of what the surprize could be "till" we arrived. Just as we pullout into a large parking lot, I saw a big train! I asked my uncle if we were going on a train ride "Though" he was parking his car "Whereas" he could say anything else. I knew that the surprise was a nice in a cool train. I heard a conductor blow his whistle and holler. "All aboard!" We ran to make sure we hopped onto the train
before it left "Although" we did not have running shoes on. We had a wonderful time and meet many fun people.
