Maddi deciding that with her new EE sized breasts she has no need for a DD sports bra, starts to contemplate what if anything she should do with you now.
You've always been a good friend but then again this is a chance for Maddi to get whatever she wants and with the Medallion she can always make new friends.
"hmmm, what have I always wanted" she thinks, "I know! I wish that Alex would turn into a cute little Labrador puppy, I've always wanted one of them to love and take care of"
Alex turns into a little puppy and is left to wonder if he will ever be turned back to normal or if he will remain a puppy until the end of his days or Maddi decides to turn him into something else. Alex remembers that Maddi is known to change you mind alot on what she wants and prays that she decides that she doesn't want one of her best friends to remain a puppy for the rest of his life.
