Sky Arena

Sky Arena is a race course in the game Mario Kart Arcade GP DX. It shares similarities to Cloudtop Cruise from Mario Kart 8. The course's layout is identical to Waluigi Stadium from Mario Kart Arcade GP 2 that is mostly made up of twisty curves. The course is only available on 100cc.

The course has a few references to Super Mario Galaxy and Super Mario Galaxy 2.

Course layout
The track takes place in the sky, with Bowser's airships flying in the background. The banner of the course reads: "Jr. Jr." with a picture of the Junior Clown Car on it, implying that the airships in this course are owned by Bowser Jr..

The player starts out on an airship. First, the player must head down to the end of the airship, which features a ramp with a Super Mario Galaxy-like yellow star booster. After that, the player reaches another airship, where a curve to the right leads to the first set of Item Boxes and multi-colored banners featuring the Koopalings. After a curve to the right, the racers then enter another airship, with a sign above the entrance reading "The road of pirates to Bowser's ship". Once the player exits, there is another ramp with a rainbow star booster.

Next, the player lands on a twisty road made out of clouds, which is similar to Cloudtop Cruise. Item Boxes can be found about halfway through the cloud section. After the cloudy road, the player boards a bridge that goes uphill, leading them inside another airship. In this section, there is a sign that reads "Cargo Bay". This airship features multi-colored gears and light blue smoke inside of it. Then, the road curves to the right, where the player exits the airship with a Glide Ramp shortly after.

The player glides over another airship with cannons equipped on both sides. After that, the player curves right in a sandy road. Once the curve ends, the player enters a structure with a sign on the top, which reads "Control Room". Upon entry, the road turns into a carpet. The ceiling of this section features many propellers. After a split path, the player can reach a ramp with a star booster above it, which leads to the Finish Line.
