I think you covered it well, Dude13...
Edaurdo is actually one of my favorite characters. I've never really found a good plot line in my head that has to do with him, so that's my excuse. The accent is very fun to write...
The thing is, comedy really isn't my specialty- I couldn't write it to save my life. I stink at it. The ocasional comedy I use is intertwined with drama. And what does this have to do with Eduardo and Coco, you may ask??
Well, like many people cannot see some characters in an dramatic light, I can't really see them as anything other than comic relief. I'm not saying that they aren't important characters, because they are. I'm just saying that I see them more in a comedic act, like some people don't want to see Goo or some other characters in an angsty light.
And there are a lot of lights that are and aren't on in that last paragraph.
So that would be why I, personally, have not written them very much. Although, in the next story I'm writing, Coco is included for some of it.
That was a really crappy explaination. But it's there.

P.S.- I hope it was okay, Dude13, that I posted that in your thread...
