A Spiked Crawler has a black, spherical head with two beady, yellow eyes on it. It wears a conical, black helmet with an angular antenna attached to its tip and a silver brim. The majority of its body is encased in a spherical suit of armor with eight conical, black spikes spaced evenly over its surface. This armor is primarily colored in shades of blue and white, with some red decorations on it. Its thin arms jut out of circular openings in the armor on either of its sides. Its spindly legs share a large, circular opening at the bottom of the armor, and the tips of its feet point upward. The Spiked Crawler has two Heartless emblems, on its front and another on its back, both of which are placed in the middle of a yellow ring.
The Spiked Crawler's name refers to the prominent spikes on its body, and the fact that its normal method of movement when not spinning is a slow crawl.
The Spiked Crawler has an extremely high defense, which will take it a long time to kill. When it starts spining, immediately bombard it with Thunder Magic until it hits. This will stop the spin and will then be able to take damage, so start hitting it at this point. Using Thunder Magic after the spin can also take a toll on its health. If you are in Story Mode, Xion will finish off the Heartless halfway through the battle, but no items nor munny will be dropped. The full battle can only be done in Mission Mode.
