I'm going to be watching this answer, as well as a bunch of other people given a certain someone that has already been proven to give themselves a BA all the time, and they lost that ID due to the team work in here.  I can only tell this person they need to knock this c**p OFF NOW.

You don't see a hump on many Red Devils in stores simply because they are very young.  The ones you'll see on the internet are usually full grown adult ones, and that's why they'll look different then the ones you see in the stores.
