Amelia Pond

I crashed my TARDIS and I'm greeted by a little red head girl who is in need
A crack in her wall has her more scared than anything she's ever seen
and so i leave a tick, and say i'll be right back, but overshot it once again
12 years later I'm back, and something came through the crack, so amy can you uncuff me?

Amy Pond just count the doors, take a closer look on the 2nd floor
Something's hiding just down your hall, something from the crack that's in your wall

So the prisoner's hiding place revealed and now it's on the run and in disguise
Then the protocol is made and it could mean the end with Earth's demise
Not much time to succeed, tracking then to proceed
and send the prisoner to their cell
I knew it found us, when Amy went unconscious
now we trick 'em hopefully

Amy Pond please you must see
Just quickly think of nothing else but me
The prisoner's captive but before they go
One more thing they need to know
Search the past and you will see
Earth is guarded so leave it be!
