the spider is not a good morph for you in your collection since you already have a bee. if you get a male that is more than one gene and breed it to your bee, you can produce a few different morphs that you can hold back, and hopefully you hit some good odds on getting females. example, if you pickup a male lesser pastel. breed it to your bee, you could produce:

spiders
bees
killer bees
lessers
lesser pastels
lesser super pastels
lesserbees
pastel lesserbees
super pastel lesserbees
pastels
super pastels
and normals
I don't think I missed any, but all these could be made from just 2 snakes, there are other males that carries more than one gene that can make many morphs, this was just an example. shows a great way of producing many snakes you don't have and holding back to grow your collection or trading for some that fits with what you have.
