Skeldritch

Skeldritch is the fifth boss in Spirit Tracks. . Its appearance is very similar to the of Stallord, a large skull with a backbone that rises from the ground, though it also sports a large Viking helmet.

Strategy
Skeldritch will fire large rocks at Link, at which point, he will need to use the Sand Wand to create walls of sand that will deflect the attacks. He can then pick up one of the rocks, launch it off a nearby catapult, and fire it back to one of Skelditch's vertebrates to destroy it. However, the last three bones are protected by armor, and are only open in a certain spot, while he attempts to attack Link with laser beam of sorts. When merely the head is left, it will float around the arena, and try to ram into Link. If he creates a sand wall, Skeldritch will try to penetrate it, and Link can sneak behind it to land blows on the Rupee-shaped Weak Point behind the skull.
