The SpongeBob SquarePants Movie
GameCube - 1080p
American (NTSC-U) Version
Rock Slide - 3:25
World Record as of 5/29/18

I discovered these 4 shortcuts back when I was a kid.
Later I uploaded a record featuring all of them and was the first to show some of them.
   • The SpongeBob Movie Rock Slide 3:28  

Previous World Record 3:26 by Sandmanfan
   • Rock Slide - Time Challenge in 3:26  
Heavy Iron Studios Time - 3:33

Optimizing this a little more and 3:24 would be easily possible. But I didn't feel like going further on this one.
