	Shortly into the level, there is a rotating pinwheel directly below a wall. Yoshi can pass through the wall by simply standing on one of the pinwheel's platforms, and when he collides with the wall, the player can tap left a couple of times. Tapping left makes Yoshi walk on the platform, and the game tries to keep him there while disregarding the wall. When done properly, Yoshi will not be hit by the watermelon seeds spit from the right. Once the wall has been clipped through, Yoshi can jump up into the secret area.		Shortly into the level, there is a rotating pinwheel directly below a wall.

	The rock needs to mostly obscure the keyhole. Yoshi must then get below it and stand slightly on the incline. The player must then hold right, hold Y, and then jump in roughly the same manner as the egg-grabbing section. The key should now be much closer, possibly inside the wall, or have come all the way back to Yoshi. If it is stuck in the wall, simply push the rock to the left and tongue at the key again. It should now be able to pick up, thus saving a lot of time. There are several methods to getting the key with and without the rock, with varying degrees of difficulty.

	Performing the glitch is believed to be a combination of the 2-2 Null Egg and 3-8 Softlock. However, this does not appear to freeze the game, only providing entertainment value. It appears to be caused by the null egg glitch, followed by a frame-perfect hit on the piranha plant right before the goal ring. Yoshi must be eaten by it at the same time an egg hits it. Doing so causes the piranha's sprite to glitch out, spit out Baby Mario and Yoshi, then slide away. This glitch has only happened to Hyperzoot and has not been reproduced.

	This glitch needs more testing.

The idea is supported by the Chomp and rolling Shyguy both using Mode 7 for their animations (maybe also the goal ring?). You can also despawn the info box above the chomp rock in 1-1 using this glitch. This glitch is also said to occur in 6-3.		This glitch needs more testing.

	Entering a goal ring simultaneously as taking a hit causes the game to softlock.

	Yoshi ~~needs to spit~~ out an enemy ~~at the same time~~ as ~~entering a~~ save ring~~. The enemy turns~~ into a star ~~as usual. However~~, ~~the game thinks Yoshi has both the enemy and the star held in his mouth, which~~ leads to ~~a glitched state.~~ Yoshi'~~s cheeks are bulged, but pressing Y results~~ in the ~~tonguing action. Using~~ the ~~tongue is pointless~~, ~~as nothing new can be eaten. Getting hit~~ and ~~reclaiming Baby Mario fast may softlock~~ the game.		Tongue Glitch is a glitch where the game still thinks Yoshi has a sprite in mouth but doesn't. Most common way is spitting out an enemy as you enter save ring (turning it into a star),
			this leads to Yoshi being able to stick out their tongue but can't grab enemies or any other sprite. Getting hit in this state while tongue retracts causes the tongue to not properly reset back and will infinitely travel backwards causing the game to write too many sprite graphic entries, eventually corrupting sprite values and crashing the game (usually).

	The player must steal the egg from the rat near the end of the level without killing the rat.

If the player is unaware of collecting the egg and proceeds normally, it is very likely that the game will crash when entering the goal ring.

The glitch is done by pressing (and holding) A and B in quick succession. It is not believed to be frame perfect, but likely a couple frame window. Yoshi will then launch high into the air.
