There's a rumor (not sure if it's canon or not) that gyroids are actually haniwa figurines which are clay statues that are buried with the dead. I was doing a lot of gardening and digging up holes to make my town look nicer, and I was noticing that there were much more gyroids than usual, I dug up maybe 10 or so. I took a break from planting trees for a bit to talk to one of my favorite villagers, Muffy explained that gryoids show up much more often after a heavy rainfall, and it was raining at the time as well. In my mind I was thinking that there were shallow graves underneath all my grass or something. I mean, probably not..but the dots seem to connect in an unsettling way. ._.
