It's in the grass lmao, it's so small you almost miss it, in the patch in front of the small island with the tree. I also spent a good amount on the bike in the grass looking for it, I almost thought it was an error too after I found all the other encounters. https://gamewith-en.akamaized.net/img/original_240a170076379e9fe5178188c8886368.jpeg now I don't have to worry finding it in Giant's Mirror. PS: It's in Bridge Field in Fog weather only.
