The Ghost

The Ghost was a Russian espionage agent who turned up on the island trying to scare the Castaways off to procure the off-shore oil rights. His real name was unknown, but he floated through the hut area moaning and sticking Mr. Howell's practice polo pony in a tree. Upon realizing they could not leave, he arranged to leave them a boat, but the Professor deduced he might be trying to kill them. The Ghost eventually fled the island upon thinking he was haunted by the Castaways he supposedly killed.
