Rotting woodchuck after being skillfully taken out of commission via firearm?

Magnification of printing on a US dollar ?

that's a clever one. I'm interested to hear if it's true.

chewed yucky dried goop & cocoon are all on the right track.

Everything else, not so much.

Hairball?

Glatt already guessed hairball, and no.

pushmower scrapings?

I was guessing a different kind of hairball.


Is it a low-quality beaver hat?

Owl pellet?

chewed dried goop and cocoon are the right track.

Hairball, vomit, fur, woodchuck, mammal are all off track.

Here's another clue:

It is water proof and fire resistant.

Wet carpet
or rug

I'm not sure a wet carpet is technically water proof...

wasp/yellowjacket/hornet nest

Yes! What a mind.
The bands of color are from the different wood/plant sources. This was from the forest. I saw a lot of moss/algae on the trees, that's where I suspect the greenish bands came from.
