It Was Never Claimed
My dad worked at Disneyland and one of his jobs was a diver on Jungle Cruise. Basically, they’d swim along the boat path and clear debris/check for any issues.
He told me that one time, among the many strange objects they would find in the water, he found someone’s leg. Not a real leg mind you but a prosthetic. It was never claimed either. How someone could lose their fake leg AND not report it is beyond me.
