You don't need to go [i]in[/i] the water even if you wear a swimsuit, y'nkow? Plenty of ladies who go to the beach or pool and just lounge around, never going in the water. ;)
Of course, we could just have some of the wizardy characters cast "Resist Water" or "Lamination" on Flan if she wants to step in.
A swimsuit fundraiser is very important though. I support this idea.

I thought that slime [i]was[/i] the bath? It isn't present when all the Nazerick doods are bathing together though, so maybe not... Hm.
