Well, the basic idea is, my sister found his egg, within a "Swifter" package. Meaning that, when she found him crawling inside the house, we figured out that he survived, because he hadn't hatched yet.
Currently, he/she is a baby. (We don't know yet, about whether or not, our lizard is a boy or a girl.)
The basic idea is, this appears to be a lizard, who's egg, came ALL THE WAY, from Australia.
And he's currently nice and safe; we even got him/her a decent plastic cage, to start out, with. But, when we get a new cage, we'll be able to see this critter more easilly.
Regardless of this critter's gender, we call him/her "Speedy". (Because he/she is quite fast, for such a tiny baby lizard!)
Another fact about this critter; he/she is also known to burrow underneath the moss, within the cage. XD
I'll try taking pics of him/her later, once I get a new cage, where it's easier to see him/her. But however; I DO plan on taking pics of the gerbils, Ivory & Ebony, soon enough.
Update, from 7/10/2017, on 8:55 PM: The little guy now has a much bigger cage, than his previous one. But, he's still shy. I tried to talk to him often, and still do. He's very quiet, to be honest!
