I'd assume she works like Buu, since Buu ate a lot of people, which includes 18, but his appearance didn't change, he had to specifically absorb Piccolo, Gotenks and Gohan to change his appearance. I'd assume turning someone into candy and eating them can also work, since that's how he went from skinny Buu to super Buu, but it's possible that only works because that was a Buu eating another Buu.
