3-3 Glitch
What It Is
The 3-3 map corruption trick allows you to skip the submarine section by doing the tongue glitch to rearrange the objects in the level to allow you to reach the second middle-ring from the second screen and you need either a POW block or a big egg to do it. Big eggs are recommended, as there is no known way to consistently get a POW block, but there are strats for bringing a big egg from 2-7 into 3-3.
This trick used to save around 40 seconds in the Any% Warps, No Null Egg category but since resetting the console between worlds was allowed back in May 2017, via a vote in the Yoshi discord server, the trick now saves around 20 seconds. A comparison video can be seen here.
This trick is banned in Any% Warpless.
Big Egg Baxter
You need to Baxter a big egg all the way from 2-7 to 3-3.
For 2-8:
- You simply want to be holding the egg before the boss explodes.
- To be save you should already start holding the egg when giving the pot the final push off the edge.
OPTIMIZED strat for the 3-1 and 3-2 Big Egg Baxter!
(Read the description of the video - Advised to be learned!)
Tongue Glitch
In the 2nd screen of 3-3 with a big egg, grab an enemy, throw the big egg into the air, and spit out the enemy right before the big egg lands. This will activate the Tongue Glitch. To see this in action go to the Tutorial.
The following video displays the 3-3 Tongue Glitch Submarine Skip using a POW BLOCK.

The following tutorial explains how to carry the big egg from 2-7 to 3-3, and also explains the Tongue Glitch.
Big Egg Baxter Visual Cues
If you do "slow baxters" (Where you visually confirm the egg position first) the following picture will help you to know where you have to put the egg so the next Yoshi can pick it up or where it will fail. For 2-7 it's fairly easy since the camera isn't locked, but for 3-1 and 3-2 the camera will be locked stupidly, but it can be somewhat worked around if you know where to put the glitched out big egg. Reminder that the big egg despawn if too far off-screen.
