I've been investigating and gathering information on the humans (and other non-Cybertronians) here myself. I can forward you a copy of my data so far, if you'd like.

However, I can tell you that humans are not poisonous nor do they spew acid, and on that note, don't think too deeply into what a certain mono-eyed Autobot with a helicopter alt mode and twisted sense of humor tells you. [Way to be vague, bro.]

As I see it, the humans are here for the same reason we are: that is, not by choice. So in a sense, we're all sort of the same. One shouldn't be too quick to judge others, you know. [huff]

Also, I've heard something about soccer. It's related to human feet. Somehow.
