[SMM2 Team 0%] DEAR MARIO COUNT ME IN

Course Code: 85V-DS8-PJG
So for my 500th clear for Mario Maker 2 Team 0%... I decided to torture myself with one of the worst courses I've ever played! This is pretty much a 7 minute long puzzle troll course FULL of softlocks and darkness!
If you need help with this abomination, MAKE SURE you plug the course code into Wizlus's level viewer! ! I'm gonna go into a bit more detail on how you beat this course below, because this video might not make a ton of sense without it!
The Objective: You must collect every Pink Coin and kill every Koopa to win! However, you must do things in a certain order and way or else you get softlocked!
Pink Coin 1 & Koopa 1: I choose to get the "big stiletto" coin first. You'll need that hidden block with the Fire Flower, and use the invisible block with the Koopa in it to hit the Switch. Make sure it's in the Off state... or you lose! So fire ball the koopa as it ricochets back. After that, make sure to hit those bricks you pass by, it'll save you near the end later! If you go to small Mario, just exit the pipe then re-enter to grab another invisible block Flower (there's two in that area!)
The goal in that stiletto room is: unleash the Stiletto Goomba and get into the boot WHILE you are still big. Then inch your way to that pink coin without going fully past the one way, as that's a softlock!
Pink Coin 2: You'll need the big stiletto again to kill these spinys. I make a mistake here: I destroyed all the blocks. Try to hold up to do a "soft pound" so you leave the last hard block alive. It makes squeezing into the pink coin and door tougher (though you can grab the 3rd fire flower), but it'll make the toughest part of the course easier!
Pink Coin 3: and Koopa 2: GRAB THAT POW! You'll need it to destroy a muncher all the way to the right. Once you do that, there's a pink coin on the vines and a large Koopa that instantly dies in the ? block. MAKE SURE YOU GET THE SPRING IN THE HIDDEN BLOCK ON THE VINES TOO!
Koopa 3: Bring that spring to the section where there's a one way and a koopa in the bricks... don't go in the one way, it's a softlock! The goal is to throw the spring from the cloud (which indicates the right position to throw it!), then grab the hidden shellmet next to it, DON'T PUT IT ON! Throw it, the shell will spawn a large koopa that dies instantly!
Getting The Racoon Leaf: Get ready, this is when the course gets REALLY dumb! So first, grab that shellmet by jumping on it and grabbing it without going through the one way. DO NOT PUT THE SHELLMET ON, YOU LOSE IF THAT HAPPENS NOW! Take it to the pipe with the 4 coins, the other ones are softlocks! Go down the blue pipe and again, DO NOT PUT IT ON! Make sure you are directly on the pipe before you go down it! Next up, take the shellmet and hit the brick, you need that Racoon Leaf! If you miss it like me in the video, you can still run down to it! There's a reason I bring the shellmet with me...
Optional Soft Lock Prevention: I throw the shellmet at the on/off switch, and hit the shellmet with my tail. Make sure the switch is in the ON position, this can save you from one of the worst softlocks in the course. See that Red Pipe? It's not enterable, if you fall down there while you're small (which you will need to be soon!), you LOSE!
Becoming "Small Spiny Shellmet Dry Shell Mario": Yeah you need to be in THAT power-up state! This is why I suggest not destroying all the hard blocks for Pink Coin 2: those spinys will wander and be a real problem! So first off, make sure you tail hit the Spiny Shellmet invisible block. Then after that... leave it for a bit, you need to hit the spikes after dismounting the Dry Shell so you can be small. After that, go back to the Spiny Shellmet and put it on!
Koopa 4: I didn't get this 4th but... you can finally kill that Koopa that's in the hole in the wall! I would not jump directly under it, as jumping to its exact location is another softlock!
Pink Coin 4 & 5 & Koopa 5: Enter the room I do in the video, and go underneath the hard blocks. That's right, one of the pink coins is in the lava! There's a koopa invisible block here too that you'll need. You won't need the dry shell after this.
The rest of the Pink Coins and Koopas: Go up that invisible vine block, and break it after its down growing. Grab the star and kill those thowmps... WATCH OUT FOR THE BLASTER, THAT MUSHROOM SOFTLOCKS YOU! Grab another pink coin, then hit the note block. This is why you need to be small! Scroll up a bit so the P-Switch spawns, then use it ONLY when you are at the muncher in the clown car. Make sure to get the final Koopa in the invisible block next to the P-block, then use your spiny shellmet to break through the hard / ice blocks to grab the final Pink Coin!
The Finale: MAKE SURE YOU ENTER THE CORRECT DOOR (Door D in Wizulus's Level Viewer), then use the Fire Koopa Clown Car to get the hell outta this nightmare course!
This course was a sadistic nightmare, it's impressive but awful!

This is one of those levels where even after seeing the whole thing I still have no idea what you did to win. YIKES.
Great job, you REALLY took one for the team here!
Out of curiosity, are you going slowly for your own safety or does the level actually require you to play slow or else get softlocked?
