List of Super Mario Bros. 2 glitches

This is the glitches found in Super Mario Bros. 2

Walk Up Walls
In any level that has brick walls in them, it is possible for the player to super jump into the edge of the walls as Luigi and can walk straight up the wall.

Climb Over a Vine
In any level with a Hoopster, the player can climb to the top of a vine and continue to hold up. If a Hooper happens to come up to the top of the vine and push the character up while the player is still holding up on the controller, the character will be in the climbing animation a few feet above the vine. The character will fall as soon as the player lets go of the up control.

This also works in the All-stars and Advance versions, except the player will need to hold up on the directional pad or else they will pop off the vine.

Defeating Birdo with a Key
This can be done in level 1-2 of the game, as well as all of its remakes. After the player gets the key, (The player can only do this with Luigi.) the player must do a Super jump off of a Ninji, and then the player will find the door to the Birdo battle. If the player can go into the door with the key, unlike Mushroom blocks and vegetables. They can defeat Birdo with 3 hits with the key, although Phanto is still there to attack the player.

Stuck in a Mushroom Block Part 1
This glitch can only be done in Super Mario Advance. It best works in the Fryguy's boss fight area. If the player slides underneath one of the flying Mushroom Blocks, the player will have to let go of down on the controller. The character's whole body, except for legs, will be trapped inside the Mushroom Block. The only way to get out of it is to slide back out.

Stuck in a Mushroom Block Part 2
In certain areas, the player can throw a Mushroom Block onto the platform above the player without running or jumping. When timed correctly, the enemy will become trapped in the block.

Stuck in a Mushroom Block Part 3
Anywhere there are enemies and Mushroom Blocks, the player has to leave a Mushroom Block where an enemy first appears on the screen, and the player has to leave the area without going up a vine or through a door to another area and without attacking the enemy. When the player comes back, the enemy will be trapped in the Mushroom Block.

Where Did It Go? Part 1
In 3-3, in the underground portion, it is possible to freeze a Mushroom Block inside part of a chain, and it takes on the chain's palette. If the player leaves the area and come back (without going through a door) the palette will return to normal. If the player picks up the Mushroom Block, the chain it was in front of is no longer there.

Where Did It Go? Part 2
In the same area, if the player throws a Mushroom Block from the platform next to the chain, the player has to wait a few seconds, then follow. It disappears until the player goes through a door.

Definite Death
This only works in Super Mario Advance, and requires Mario or Luigi. In 2-1, a wall while digging through the sand exists. The player should super jump with the key up to it, and once they touch the wall, try to throw the key. If done right, they'll be stuck in the wall. The Phanto will be delayed for about two minutes, but will eventually swoop in. The only controls are left and right, though they make the character walk nowhere.

Rolling Yoshi Egg
This glitch only works in the Super Mario Advance. First, go to level 2-2 and play as Luigi.You must have at least 3 hearts. Go into the tall vase shortly after finding the mushroom. Once inside, pick up the strange ball. Then, run into a Spark (at the top) and try to get to one side or the other (this part is easier the more hearts you have. You can't do it with only two, as when you shrink it won't launch you). Then, carry it out. It will become a Yoshi Egg with the palette of the ball. It will act the same way, with the exception of being re-usable if it falls in quicksand.

Super Mario Bros. Music
To do this glitch the player will need to grab a Star and go in the Subspace and quickly go out while they still have the star. If the player did it right then Super Mario Bros. music will play until the player leaves the area or goes in a door. It's also possible for the player to get that song to play for the remainder of the stage (until dying, going through a door, or a jar), if he or she stays in Subspace until the invincibility wears off.
