<P> Riders then board steam - powered mine vehicles that travel through pre-drilled tunnels into the heart of the Earth . The ride begins through a cavern of colorful glowing crystals, before entering a giant Mushroom Forest, which is inhabited by strange insect and amphibian - like life forms . Before the car can proceed further, an earthquake causes a cave - in of the tunnel ahead, forcing the car off its planned route and down a side branch filled with giant egg - like sacks that appears to have been dug by some gigantic animal . The car emerges on the shore of the Subterranean Sea, and is nearly struck by a lightning from the electrified gas clouds . The finale comes when riders are forced into the fiery heart of an active volcano, where the riders come face - to - face with the giant centipede - like lava monster that has built a nest there, before escaping back to the surface on the wave of an eruption . </P> <P> Journey to the Center of the Earth was originally planned as a free - fall type ride as part of Discovery Mountain, a former Disneyland Paris concept in place of Space Mountain . Since it was never built, this project reemerged in Tokyo DisneySea with new technology from Test Track, a thrill ride through a GM testing facility at that time . </P> <P> The score of the ride was composed by Buddy Baker, who was also responsible for the scores of rides such as Pirates of The Caribbean and the Haunted Mansion . </P>
