Why would a spider share a human disguise container with a amphibian??????

This form of mutualizm. Is most often found in ANDROIDS: Synthetic people artificaly created from bio-matter.

What enzynes or petroleum products do they exchange with each other?

Once the amphibian (toad or salamander) is terminated, the spider still in a human hide disguise. May explain, a great relief and state how it was enslaved by the amphibian and chastise to work for it.

Just what do you know on the subject.

I really don't understand what you are on about sorry!!
