Flora, you should have known better than to eat the watermelon seeds! It wasn't just an urban legend after all!
Or it's the baby. That's possible too. At least she's finally filled out on top like she wanted, but how can she enjoy that when she's barely able to lift herself to walk around now?
On a related note, have you ever really stopped to think about the whole pregnancy thing? No disrespect at all to the women who go through that experience, it's an amazing thing. But I imagine if an alien saw someone 8 months pregnant and had never heard of the process of mammalian live births before, they'd find the whole concept pretty disturbing.
