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.
