Writing starter 40

It was a quiet Christmas morning, when everyone was asleep.  There were but 2 children awake.  They couldn't sleep, they were too excited.  In a few short hours they would be opening presents!  They sat at the window, staring at the snow, when suddenly something changed.  The snow wasn't snow.  It started changing color, changing to blue and pink.  It was no longer cold, and no longer water,  it was cotton candy! They woke their parents who then called the neighbors, who called their neighbors and neighbors.  The candy was plush, and sweet, and colorful.  But soon the real reason is revealed.  A mad scientist had changed the weather to make everyone eat the candy, which made them want to buy a strange pet from that weird store on 3rd street.
