Cragma

Cragma is the fourth boss in Spirit Tracks. It has the appearance of a large and menacing, molten rock cyclops. In the PAL version of Spirit Tracks, Cragma is named Vulcano.

Strategy
In the beginning of the fight, Link merely fires an arrow at the multiple Weak Points around Cragma's body. Afterward, he will cause molten rock to fall from the ceiling, which Link then must lure his fist to make contact with the flaming boulder. Then a platform will appear, which Link can carry with him, as he must bring it to a nearby Mine Cart. Once the platform is in place, Link can hop into the cart, and it will then revolve around the boss in a similar fashion to the Stallord fight in Twilight Princess. Once he is level with Cragma's eye, Link can then hit it, causing the boss to be stunned, and vulnerable to the an attack.

Trivia

 * Cragma's name is derived from the words "crag," meaning a rift or break in rock, and "magma," referring to his fiery nature. His PAL version name, Vulcano, is a reference to the word "volcano," and possibly to "Vulcan," the Roman name for the blacksmith god Hephaestus.
 * Cragma is possibly the largest boss Link has ever fought, along with Eox, Dark Dragon, Bongo Bongo, Molgera, Morpheel, Skeldritch, Stallord, and the Demon Train.
 * Cragma shares similarities with Hinox and Stone Hinox mini-bosses from Link's Awakening.
