So, my new neighbor - Mr. Woodchuck - showed back up tonight.

7. Well, he dug under the block foundation and popped up on the inside of the dirt crawlspace.

The crawlspace is just dirt, without concrete flooring, unlike the rest of the basement. And once he dug that hole, all other kinds of woodland creatures used that tunnel to enter the crawlspace and into the basement proper. While the crawlspace is mostly closed off from the rest of the basement, there's enough opening for voles, squirrels and rabbits to enter.

This guy had their four season home under the deck and summer cottage under the shed and go between the two. The under deck one was used in winter, even before entering the crawlspace. It took a few years before they dug under the foundation. I guess they liked the slightly warmer and sheltered environment.
