I’m pretty sure that what you are seeing is the shoes and legs of the person laying on their back to the right of the person whose head is visible. Especially img# 6, 7, and 8.
I agree with you Dan.
At first it looked spooky but at closer inspection it appears that Fuddy is on her back and facing the camera; her face is partially hidden by the “May West.” She appears, possibly, to be “bicycling” her legs. That’s why her knees (the frogman) are “coming up” and occasionally her yellow tennis shoes appear also.
That’s what I see. Can anybody verify what kind of shoes she may have been wearing that day?
