TARDIS on a Cloud 

Based on Castle on a Cloud from Les Misérables and Doctor Who S07E06: The Snowmen. Lyrics: ailaG

There is a TARDIS on a cloud

I think that is where tales begin

Smaller outside than it is in

Such is the TARDIS on a cloud

There is a room that's full of lights

There are a hundred pulls and knobs

No scary snowmen are allowed

Not in the TARDIS on a cloud

There is a gent in a bow tie

Beckons and bids I come inside

He's nice to see in his box of blue

He says, I don't know why I just know who...

Then I am swept, then I am lost

On Christmas night I fall and die

Crying was all they did that night

Down there at home and on the cloud.
