"Help me! I'm crashing!"
A Foreign spaceship was crashing towards Earth, at full speed and the engines busted. Inside the ship, there was an unlucky pilot who goes by the name Cass, panicking what to do next to avoid her death.
"THE SYSTEM HAS BEEN SHUT DOWN." said the computer voice.
"It's not like I need a doctor!" she replied.
Just then, a blue police box hovered towards the crashing ship, and managed to get in.
"SYMPTOMS INVOLVE NAUSEA, IRRITATION, AND PARANOIA. YOU REALLY NEED A DOCTOR!"
"I already know what's happening, and stop talking about doctors!" she commanded.
"I'm a Doctor!" someone said.
Cass turned around to see a man with a purple scarf and a jacket.
"..and not the one you've expected."
So this was a little idea of what "The Night of the Doctor" Frozen style would be like. So Let's see how it goes!
P.S. The ship was crashing towards Arendelle. Just a Heads up!
