A glitch allowing the boss key sprite to be captured in Yoshi's Egg stash has resulted in an entirely new set of strategies that must be developed for every level after 2-2.
2-2 Null Egg Setup-1
1-8 Null Egg Salvo Refight-0
Script for understanding null egg (thanks arne): http://www.mediafire.com/?mohrxu7p03c645x
The Boss Key sprite affects a few levels differently between versions. The version that a strat works on is specified for each level that has differences. The strats are from slowest to fastest.
Version tiers: J1.0, J1.2, J1.1, U1.1, PAL, U1.0
The position the key is in affects how quickly it ends the level.
Compared to having 3 eggs in front: Having 2 eggs in front losses 9 frames per level, having 1 egg in front losses 47 frames per level, having no eggs in front losses 49 frames per level.
Save Corruption[]
3-1 corrupts save data with boss key - sometimes it can unlock arbitrary stages (usually w6)
TODO: stuff
World 2[]
2-3: (RNG)[]
Move as far into the level as possible blindly. Do not let input end while you're on a slope.
2-3 Any%-0
Things that can end your run:
Getting hit and not recovering Baby Mario.
Random Gusty spawns.
Throwing an egg acts as a decoy for 1 of the 2 gusties but will cost over 10 seconds from key loading times.
2-4:[]
Run as far right as you can
2-4 Any%-0
2-5:[]
Strat 1: Run past the egg spitter plant avoiding eggs as you go. Get to the peak point of the foam, when Yoshi makes his trademark sound throw an egg up. Flutter to the right and take the Lakitu cloud and move above the left side of the foam platform shaped like a line where the yellow shyguy is. (The earlier you throw the egg the sooner the level ends. The point I described is about the latest you can throw it.)
2-5 Any%-0
Strat 2: GP the foam at the edge of the
first platform. Move right and flutter left against the wall. Flutter again under the stage to the left.
Here's the GP sweetspot:
You can also use the other strat as a backup if you don't get a good GP.
2-5nullegg
Things that can end your run:
Getting hit and not recovering Baby Mario.
Having the cloud drop you while there's no foam under you.
being too far left or right under the stage.
Collecting an egg can give you trouble in 3-8 and 6-8.
Backups:
if you miss the cloud then run left and try to get back on it.
If your 2nd flutter doesn't go under the stage end the flutter early and flutter to the right.
2-6:[]
Run to the right edge of the foam and hold up.
2-6 Any%-0
2-7:[]
Get hit save frames, and hold up while facing right.
2-7 Any%-0
2-8:[]
Move to the position shown in the video.
2-8nullegg
Probably better to be too far right.
World 3[]
3-1:[]
Strat 1: do nothing. (U1.1; J1.0; J1.1; J1.2)
Strat 2: Run forward as far as you can. (J1.0; J1.1; J1.2)
Strat 3: Run to the right and tongue or stomp the Grinder (monkey), then flutter low and to the left into the wall. (J1.0; J1.2)
3-1 Any%-0
Backups:
If you fail to grab or stomp the grinder then run right.
3-2:[]
Run past the first Milde and turn left. Jump on it at the last moment.
3-2 Any%-0
Things that can end your run:
Ending on the left side of the screen.
3-3:[]
Bounce on the grinders to avoid going by the egg splitter plant. Jump into the Nep-Enut (around the middle) and swim to the left.
3-3 Any%-0
Things that can end your run:
Collecting eggs can cause trouble in 3-8 and 6-8.
Landing in the water too close to the left wall will make it unable to scroll properly.
Backups:
If the screen doesn't scroll jump out of the water and grab baby Mario.
If you mess up movement at all it's likely you wont make it in time. In that case face to the left next to the pole.
3-4:[]
Run by the shyguy and then run left into the water. Up tongue to avoid eggs.
3-4 Any%-0
3-5:[]
Spit the first grinder into the 2nd grinder. Move back to the left edge of the foam and don't move until the screen is white. Flutter under the stage.
3-5 Any%-0
Many odd things can happen on this stage. if you wish not to deal with it simply stand still.
3-6:[]
Spit the 1st 2 grinders (monkeys) into each other and hold left.
3-6 Any%-0
3-7:[]
go right and jump on the first Stilt Guy, then grab the shyguy and go back to where you started. Lose control while in the water, moving left, and staying on the right side of the screen.
3-7 Any%-0
Backups:
If you miss the shyguy run right while staying out of the water.
3-8:[]
Check your egg count for how many eggs you have (not counting null egg). You must have 4 or less, if you have more throw some.
Go into the pipe. Tongue the first Shyguy. wait a moment and then get hit by the second and damage boost past the 3rd. Now spit all 3 Shyguys into the sewer ghost. Stand in the lower area and face to the left.
3-8 Any%-0
If you have 4 eggs you have to do this strat but with 2 shyguys instead of 3. Wait longer before running into the 2nd shyguy.

If the dazee spits bubbles and blocks your tongue (if that's possible) then you then travel right as much as you can. if the keyhole disappears before you reach the end the game is probably about to crash. (idk why)
