My mom had a stuffed sheep as a kid (it's in her bedroom at Grandma's house) that looks EXACTLY like the scary lamb pendant.
That last one, I like for Mercy... none of these are quite what I imagine it to look like, I'll have to go searching. I actually had a green glow-in-the-dark lamb charm thing when I was little, if I remember right; I picture Mercy's lamb to be a little bit more like that, except (when in non-vampire-repelling mode) silver and not glowing.
