An edited photo of two wild mushrooms on a grassy slope against a blurred mossy stone wall. They both have hollows edited on with eyes drawn in, and the one on the left has a row of mushroomy teeth hanging down from a light brown cap. The one on the right has turned up on itself so the frills are visible, and has turned redder. It had a pock mark on the stem which looks like a slightly surprised mouth. Overall impression is probably goofy rather than scary, although I even tuned the colours to be more sombre.
