Ushi No Tane Forum

I just tried searching the forum to see if this was already answered, but I couldn't find anything...

My question is, I have now unlocked the field behind the waterfall, and the first time you walk into the field each day, a spot on the field will sparkle momentarily. Does anyone know if there is anything significant about this sparkle?

It's a super growth field so I think it just shows that it's special or something.

I have that too, in my chicken barns as well though they look like foot prints
