Pretty much this. I still wonder why he wanted an army of Robo-Fortunes to begin with.Anyhow, I wonder what the hell was going on in Brain Drain's Brain Jar for him to think that using the Skull Heart to power his army of Robo-Fortune 2.0 was a good idea. I'm guessing along with being a power source, it makes it possible for no one to get their hands on the Skull Heart to make a wish themselves.
