Jimmy Squarefoot
Jimmy Squarefoot is the phantom of a man with a pig’s head and two huge tusks like those of a wild boar. Jimmy Squarefoot, the name of the man who became the odd phantom, haunts the Grenaby district of the Isle of Man. located between England and Ireland. According to lore, at one time it was a giant pig which was carried around by a stone-throwing giant, a Foawr. As a mortal, Jimmy, too, was a stone-thrower; his favourite target was his wife. She ultimately left him, after which it seems he assumed his semi-human form and roamed the land. Stone-throwing is a common phenomenon of Poltergeist cases.
