Thanks everyone! The winning idea was: "How about what would have happened if Salt had been "Fertilized" In the comic. Mostly I just want to see slug babies."
I'll be honest, I didn't expect this one to actually win! I had intended for this poll to be a way to try some new ideas and a get bit of variety but I guess you guys just really like Pepper and Molly huh? :D
Anyway I've decided I'll be making this as a sort of "What If?" short epilogue but I'd really like to do it once I've actually completed the initial comic first. It'd just be a bit strange to do an epilogue before the actual ending :S
So for now I'll be going ahead with the 2nd place winner: "Office lady about to burst out of her clothes by turning into a blueberry!"
Sorry if this a disappointment for anyone. :(
