It was really strange. I looked and nothing there. Then I looked after my first reply and there was the mole rat layin' in the middle of whatever that is (an intersection of a maze or something). Then I saw what looked like a mouse walk over it and stopped and looked like he was wiping his feet or trampling on the mole rat.
I think the overhead view of that intersection makes the little guys kind of hard to see. I looked at some other pictures on a few sites, and those pictures look very similar to the mole rats in the ratcam. Interesting, anyway.
