Call it a UFO: an unidentified floating object. Beachcombers were baffled over a creepy, “skeleton-like” figure with fins that washed ashore in the UK, as seen in viral photos making waves online.

Earlier this month, there were sightings of an unusual, enormous ball-shaped unidentified floating object meandering around in Puget Sound. The device is not of alien origin, no matter how it looks.
