Test Course 9's dash tiles don't seem suited for this purpose, plus they're using the 2×2 tile graphics instead of the 1×1 graphic of Special Tee Shot, so this rules Test Course 9 out. Once the ball hits a stage border or an obstacle, the ball stops and the player regains control.

While boosted, the ball can also climb up slopes and walls. The dash tiles in Special Tee Shot don't just speed the ball up, but force the ball in a certain direction at top speed and the player loses control of the ball. Test Courses 6 and 8 have warp tiles, so they can't be from Special Tee Shot, whereas Test Course 7 is an early build of a hole found only in Kirby Bowl. This helps to rule out certain test maps as Special Tee Shot leftovers. Objects that Special Tee Shot has no version of are spikes and warp tiles. Scenery it has similar versions of are dash tiles and stage borders. Let's start with the scenery in Special Tee Shot: the objects it shares with Kirby Bowl are sandpaper, arrow tiles, conveyor belts, water, directional grass, and trampolines. There's some strong proof in the way Test Courses 1-4 function that gives them away as leftovers from Special Tee Shot.
