Thanks guys, I had better luck finding info. on them when someone pointed out to me that they're also known as ackies! lol. See? I told you I didn't know much about them.
I think I'm going to kidnap him/her this weekend when they're gone and set her up in one of my 75's. Trust me, my friend really won't care if I explain things. Besides, I raise mice and he doesn't, and right now I have more pinkies and fuzzies than my snakes can possibly eat.
Thanks again. I'll get a picture this weekend and post it here. Hopefully someone can confirm that s/he is indeed a yellow ackie.
