So a spider... Wouldnt that be codom because it can make a super, or is it considered dom since its already a visual.
Spiders do NOT appear to have a 'super' (homozygous) form. But just because nobody has ever been able to verify a homozygous spider exists, you can't really say for sure one way or the other. I prefer to play it safe and say that spiders are 'some kind of dominant mutation'

but what happens if you mix spider (dom) and pastel (dom) to make bee, wouldnt that mean the animals are codom?
The individual mutations are considered either co-dominant or dominant or recessive. Not the entire animal. You could produce a hypomelanistic pastel spider and have three different kinds of mutations in one animal, but that wouldn't make the snake either recessive, co-dominant or dominant.
