Rainbow Shell Extra Jump Height Trick

[MacheTheFerret]

Henlo all. It's been at least 5 quadrillion years.

Just recently while I was messing with potential kaizo(ish) tricks I could implement into a new experimental project of mine, I discovered an interesting maneuver you can do with upside down rainbow shells.
If you follow the steps below in the right order, and with the right timing:
1. Grab and hold on to the shell
2. Run left or right
3. Press and hold down
4. Quickly release the run button right after
5. Quickly spin jump after that
You end up jumping higher than your regular jump, and much higher than if you were to jump off of a rainbow shell while riding it normally, among several other things.
With this trick, Mario and Toad can clear a little over 8 blocks in height, and Luigi can clear 9. Link is unable to perform the trick for obvious reasons, and Peach seems to be unable to as well, but it seems to be because she can't jump off of a rainbow shell on her own, due to how her jump works. If anyone wants to correct me on that, please do.

I made a 1-screen level that showcases this trick (you're forced to play Luigi to prevent cheating).

Hopefully that link works. It's a Dropbox link, so probably not.

Hope you found this as interesting as I found it to be. Off to not-even-lurking land for another several months.

Should've recorded it & put it on Youtube. A screenshot doesn't show us anything.

Or maybe a gif?

I think I understand him.
I tried it and it works.
Ride the shell, jump and bounce off the wall then press the alt jump button to jump off the shell.

That's not what he's describing according to those 5 steps. The first 4 steps are basically HOW to ride a rainbow shell, while the 5th step says to basically just spin jump off the shell as soon as you get on top of it. I haven't tried it myself but that's what he's saying according to those steps. I'd just like to see a video of it in action.

This looks interesting, a one screen puzzle level in smbx. It's like doing one of those back in my Mario Maker on WiiU days

Considering that it's a one-screen level meant to showcase a single trick, I feel like a video would defeat the purpose of the level. But, if people really want me to, I can record something real quick and post it in the original post.

Yeah, I found this out too and it will be the gimmick used in some of my levels. Also made a level based around this in my free time as an entry to the All-stars level contest, but it got disqualified as it was only compatible with 1.4.3.
