Edwin's Shinies

I'm sure you're all familiar with DSimpson's BG Walkthrough (http://www.gamefaqs.com/pc/75251-baldurs-gate/faqs/2456). At the bottom, he's typed out the quotes for every character's sound files. I've never been able to extract them successfully, so I wasn't able to hear most of them until BGEE came out and I found a way to force some interactions between NPCs. So, now I've heard almost all of the sound files I have wanted to for the last decade or so (wow). All except the ones about Edwin's shinies.

If you check out the guide, just do a Find on the page for "shinies" - it will bring you right to the quotes in question. I've also pasted them below.

[spoiler]

"Ohh... I'm not much help for you. I'll just sit with the pretties and watch them sparkle."
"Aah! Help!"
"I sad, but... sparkle makes for happy."
I not like sad thoughts. I go sit with the pretties."
"I once had shinies piled up to the sky. I no remember where they are."
"You find me friends... ok?"

[/spoiler]

What. On. Earth. Are. These?

They sound like something Cespenar would say, only he's quite some time away. As I said, I could never get the hang of extracting and playing the files, so I don't even know if it's the same voice actor as Edwin; all I know is that DSimpson has them listed under Edwin.

Does anyone know the story behind these or how to trigger them in the game? It's driving me bonkers. (And I hope the answer isn't "It's another character that you can easily find at X" and I've essentially languished for a long time for no reason.)
