It displays that the super is just homozygous and not really a super form. It has no different look. I guess when I buy my next spider I will buy one from a spider x spider clutch and see what happens to the results. It should be possible according to the laws or genetics. Maybe it hasn't been done very often because spider x spider clutches only yield spiders and normals, but if you breed a spider to something else, like a pastel, you can get bees which would make you way more money and be much cooler than just a spider or a pastel.
