This isn't the first time Kotaku has posted about Allie Goertz. Recently, even! Last time, it was for singing about D&D. This time? More D&D.
Goertz took the lyrics from Patton Oswalt's book Zombie Spaceship Wasteland, but the melody and music are all hers.
She has other nice songs, too. Like this one.
Her friend's name is Megan. I don't know the names of the cats. Sorry!
