I'm bewildered too - those were perfectly good prompts!

I guess you could always make a new post asking if anyone wants a third prompt, this perhaps jog people's memories?

Hm, what else could we do...You could try advertising on Tumblr, maybe, using the "one piece" tag? You could stress that it's okay to use fan art as well as fic.

Maybe I could actually help with that - post links on Tumblr to old favourites of mine on this comm to let people know it exists. Hopefully that would be okay (I wouldn't actually reblog any art let alone fics without first getting permission from who created it).
