Elsa's Demise cover image (Pegasus Device parody)

"No two killings are ever the same, 
Corpses vanish at night, with not a soul to blame.
They all thought that they could trust me, but that's not wise, 
When they learn that it was I who had caused Elsa's demise." 

So yeah, I'm working on writing lyrics to a parody of the MLP fan song "Pegasus Device", with a Frozen twist.  More specifically, a "Killer!Anna" twist based off of Mary Medley's covers of "Will You Help Me Hide a Body" and "Let Them Run", the latter of which I also wrote the lyrics to.
