Thwomp Ruins

Thwomp Ruins is the fourth and final course in the Mushroom Cup of Mario Kart 8 and Mario Kart 8 Deluxe. This course takes place in ancient ruins that are populated with Thwomps.

Course layout
The race starts outside, and after a straightaway, turns left twice. Next, there is a right turn that leads the player into a tunnel. Inside, players can either drive up the wall on an anti-gravity path, or stay on the main path which curves right, where Millstones begin rolling out of a raised area. When the player exits the tunnel, they enter an open area with three routes. If the player takes the right or left turn, they can either stay on the main path where there is a Thwomp, or drive up the wall. If they drive straight, they can either drive into the water and go right or left, or go drive off a Glide Ramp and soar over the pool of water. In the underwater section of the course, engravings in the surrounding walls resemble Thwomp mouths. The gliding pad is only accessible when a Millstone knocks the ramp into place on the second lap. Once the paths join up, players will enter the mouth of a Thwomp, which is also the entrance to another tunnel, and an anti-gravity section begins. There is then a right turn, which leads to the tunnel exit. After this, there are three more turns, and two Thwomps, leading to where there is a gliding section and a straightaway toward the finish line.

In the E3 trailer, the anti-gravity section was a normal section and the finish line wasn't present on the path after it.

Shortcuts

 * If the player uses a Mushroom in the grass between two big rocks, one can cut off the first two turns.
 * The player can drive onto a fallen pillar cutting off the turn before the second glider ramp.

Mario Kart 8 Original Soundtrack liner note
"This is a bit of a tricky number, with the rhythm written in triplets. We use a gamelan instrumentation along with metallic effects to add an ethnic feel. The image we had in mind was of a ruined temple somewhere in Asia. We added some thudding percussion here and there to give an image of of a Thwomp shaking the ground."
