Haunted toilet paper roll plays the sounds of the undead in the bathroom

This is curious: it's a toilet paper roll holder that plays the sounds of the undead when you pull at the TP. OK! Not that I doubt the power of zombie moaning to help with any trouble making dookie, but is this a reference to anything in particular or just sheer randomness in action? Why zombie sounds, then? Why not, say, showtunes? Or the sound of airplanes taking off? Maybe those are being held for next year's model.
