Story about Lea's Amulet?

I'm trying to find the story describing the first time Lea gets that amulet to hide herself from predators. Can someone give me a link to that? I'd like to read about her friends' startled reactions when she wears it. I understand she doesn't wear it around them usually, but when she first got it I would guess she might not think of that.

Thanks.

It's actually more background information since it all involved Karbo's characters.

to my knowledge there isn't any stories that have been wrote on that yet

Dang. Thanks.
