Recuperation journey: Things are getting nutty around here

I saw this in the front yard this morning. We don't have any peanuts in the shell in the house, but this is the second peanut I found "hidden" in our yard.

The squirrels must be getting ready for winter, but where are they finding the peanuts?
Strange goings on around here are making me nutty.
