The Skeleton Men

The Skeleton Men are characters in the live-action serial Danger Island.
They are the third of three native tribes that Professor Irwin Hayden's expedition runs into during their search for the lost city of Tubanya. Their name is derived from the white bone-like markings painted on their skin, making them look like walking skeletons. They are initially in league with Mu-Tan and his pirates, even kidnapping Leslie Hayden. However, they eventually betray the pirates.
