So I may have found 2 skips in Koopa Cape MK7 these could possibly break the track

1. drive around the course a normally until you get to the edge of the pipe waterfall with the fences. Then try and jump over the fences and out of bounds and get back to the finish line to complete the lap

2. dive around the tracks as normally and get to the bottom of the pipe waterfall then drive backwards until you cant then jump out of the half pipe onto the other side to the other end of the half pipe then drive around normally.

Remember these are theoretical so don't shun me for saying this impossible.

I'll do the opposite and say that there is already a known glitch there by clipping the fence before the pipe :)
