(and maybe kefka gets enthusiastic talking about poisonous plants as well?)

Funny you should mention that. That plot Stanley has going on with Greed involves making plants of dubious use. I can see Kefka mentioning sudden flowers everywhere and Greed taking notice. It's all about who you know. :)

On that note, you ought to read about Stanley's Green Thumb. It's full of delicious plot device potential.
