Nuclear?

Quite a bit more of a difference if you look at all the examples on WOBP's.

I did look through the rest of the pics there, as well as a google search, and there's just so much variation I don't see how you could say they're different. You can pull up pics of just Lesser Clowns and there's all kinds of variations...same with Butter Clowns. I just don't see how you can definitively say one way or the other...
