"I've read this tablet front to back and the story it tells is very disturbing!"
―Buck to The Herd[src]
Buck explains about the asteroid

The Stone Tablet was a carved rock-like object shaped like a rectangle.


Buck, a wild weasel, found this tablet in an underground tunnel that "shows the future" in pictures.


The Tablet is carved with a picture of asteroid hitting Earth. It's a large stone-like rectangle that is carved in and appears to be held up by ropes.
