Vampirella meets Barbapapa? Vampirella meets Kimba the White Lion? Vampirella meets the kitchen sink? (Although, speaking of Kitchen Sink, I'd sooo approve a xover with Demi the Demoness...)
This better has some inner logic, throwaway gag xovers tend not to work for Vampi. Or shall just Betty and Veronica be relaunched more bad-girl-ish?
