Default Critters in the motor?

Is it possible for bugs or other critters to get into an A engine cylinder all the way from the back of the tailpipe?
The #4 exhaust valve was open for the last 20 years. Exhaust system was all intact.
Looking in the spark plug hole showed about a tablespoon of seeming organic stuff...black but not like mouse droppings, more like coffee grounds.
It was scooped out and flushed out. See the attached pic.
The exhaust valve is stuck open so I'm freeing that from inside the valve chamber by prying up on the valve after putting Marvel down the open valve.
Then I'll try to start it.
The amount of stuff in the cylinder is baffling.
The car has been in storage for 20 years, indoors, in Alaska...very dry climate.
We have honey bees, hornets, mosquitos.
Any thoughts?

What ever it is will blow out when you get it started.

Jim,
Is this the engine you have on the test stand right now?

Update...after a liberal dose of engine oil in the cyl and more cleanup, we could see both valves were working.

Even though there was minimal compression we decided to try a start.

It caught on the second pulse and ran evenly after about 15 seconds...amid a large blue cloud of oil smoke.

We'll stay cautiously hopeful and change oil soon.

Thanks for the comments...especially the DNA.

Sure, the tail pipe, or via the carb...
