Timothy petted his neice's and nephews' dog, Scooby (named after the cartoon character), for a while, with the hand he was holding the Medallion in. He put the Medallion around his neck, tying it a bit, just in case anything happened, and decided to go in. He suddenly became hot and dizzy, and he noticed everything seemed to be getting bigger.
Immediately, he realized that he was shrinking down to Scooby's small size. He tried to speak but his voice sounded like he was a very small child again. He realized he was now younger! Also, he saw fur growing all over his body, looking down at his Manhood, or Boyhood as it was, he saw it get pulled into a Sheath... This was too much for Timothy's now young mind to bare, so he passed out...
When he came to, he was a small puppy.. In fact, an Identical Twin of Scooby. He decided to take his clothes with him as he tried to find shelter for the night... He figured that tommorow, he'd be able to find a way to change back...
