yellow belly pastel

[m00kfu]

I thought bumble belly was some new gene other than yellow belly added to a pastel spider. I'm not remembering the name right now, something like black belly. Maybe I’m not remembering the bumble belly name right either and I’m thinking of something else.

You're probably thinking of the black belly. When added to the pastel gene it makes the yellow jacket (which can be found at the bottom of the page here). The bumble belly is a pastel/spider/yellow belly combo produced by last year by Marc Baily.
