So I don't know if I am sleep walking or not, but this happened overnight. I went to bed with a somewhat normal looking backyard. I only mow it, so it has wild strawberries and crap growing everywhere and tons of weeds - biodiversity maaaaaannnn.
Anyway, I woke up to this (shoe for reference):

WTF did this? Is it the start of a crop circle? I'm sure I have grubs because I literally put nothing down on this part of my lawn. Groundhogs don't work at night, right? Would a raccoon eat grubs?
