warspyking | ALT STRAT/RECOVERY STRAT for Koopa Kooperation Backshot shell jump @warspyking | Uploaded October 2018 | Updated October 2024, 8 hours ago.
Turns out some guy names NV Gamers did this in his video, so credit goes to him.

Don't want to aim the shell? Or did you just happen to miss? Very easily beat the section anyway because the spin jump is completely unnecessary.
