List of Super Mario World glitches

^LOL TWICE^ These are the glitches found in Super Mario World.

In order to do this glitch, the player must go to Yoshi's House and keep pressing the and  buttons. Sometimes the birds and berries will pause and the smoke from the fireplace will skip. If the player's lucky, the smoke will be glitchy. If the player can't reproduce the glitch after about a minute, they must re-enter Yoshi's House and try again.

To do this very minor glitch, all the player has to do is duck and jump on a fence. As long as Mario or Luigi doesn't touch the ground, he'll be ducking each time he jumps off the fence.

To make this glitch, the player must have already pressed the Red and Green ! Switches. He or she must have Cape Mario and a Yoshi in Star World 4. At the level's secret exit, he or she must make Yoshi keep the Key in his mouth and fly with Cape Mario to hit all green ! Blocks at the left. If the player drops the Key, it will be an item that changes from a Yellow Beach Koopa and a upside-down Cheep-Cheep.

The balls on Iggy's and Larry's platforms can be destroyed by the sliding attack, as can the Grinders (using a triangle block). This results in glitchy graphics, most likely because the developers did not intend for these enemies to be defeated. The same thing happens if Mario does a nose diving in the second level of the Bowser battle. The Big Steely will be defeated as the head of Princess Toadstool colored red.

In Super Mario Advance 2: Super Mario World, Iggy's ball can be defeated normally, however, a defeated Grinder is still glitchy and turns into a half of a wooden plank or a Magikoopa's magic.

In Yoshi's Island 1, the player must have Yoshi and Fire power. On the part with the Jumping Piranha Plant and a Rex nearby, Yoshi must stick out his tongue, Mario or Luigi must shoot the Rex with a fireball, Yoshi must eat the coin produced, and Mario/Luigi must collect the coin. Since nothing will be in his mouth, the game will place the nearby Chargin' Chuck in Yoshi's mouth. Chargin' Chucks aren't supposed to be eaten, so the game won't know what to do with it. It will place a glitchy item in the player's Item Stock. Depending on the level, it can show up as many things when used, including a ? Ball, a green Bony Beetle, a green Cheep Cheep, or a glitchy sprite not resembling anything. Regardless, it will act like a ? Ball. This is a way to beat a level with less challenge, and is useful for Speed Runs.

In order to do this glitch, the player must go to the end of Chocolate Island 3. Under the goal, the player must jump off Yoshi to the Giant Gate so that the screen does not scroll up. If done correctly, Mario is barely seen when he finishes the level. When he comes back to the overworld map, the entire world is glitchy and colored with red and blue. The glitch ends if the player exits the Chocolate Island area.

In Donut Secret 1, Mario must enter the Warp Pipe to the secret underground area. While Mario is on the ground, the pipes are orange, however, when Mario flies up and comes down, both pipes are miscolored green. Sometimes, the pipe gets only one half green-colored.

When the player unlocks the Secret Area, they need Yoshi and a Feather. Then the player must fly above the screen to end the level normally. The player will be sent to the hidden island. Start the level and its packed with (3-ups). When the player finishes the hidden level, graphics will glitch and the player cannot move.

When the player is on Forest of Illusion 1, the Yoshi that is found here can become a glitchy Chargin' Chuck. First the player must be Cape Mario or Luigi and defeat a Chargin' Chuck with Yoshi. After that the player must go down in a pipe with Yoshi and go back up. If the player loses Yoshi and gets an egg back, the Yoshi is replaced by a Chargin' Chuck. His tongue works normally, but the game freezes if the player attempts to finish the level while riding him.

This glitch can be only done in the GBA remake of the game.

First off, the player needs Yoshi and 999 lives. Now he or she must enter a level with possibly at least a 1-Up Mushroom (i.e. Yoshi's Island 2) that was already beaten. The player must stick Yoshi's tongue to the 1-Up Mushroom and rapidly press when Yoshi's mouth is full. The player now must select "Back" and, as usual, the player goes back to the map screen. If done correctly, the player's life counter shows up as Y00 (possibly 1000 lives). However, this is temporary, as the player enters another level the counter resets to 999.

Music speed increases when the Timer reaches 100, warning the player of the time limitation. Usually this can only happen once in a given level. However, on Funky, where the green berries appear, the player is given 20 extra seconds for each berry eaten by Yoshi. If timed correctly, the player can eat all 9 green berries, each when the Timer is somewhere between 81 and 99 seconds, and it increases the music speed up to 10 times, making it very fast. If an extra 11th green berry is eaten, the music will slow down drastically.

The glitch was fixed in the Super Mario Advance 2 remake, as the music does not speed up should the player attempt to try this glitch.

In #4 Ludwig's Castle, in the room where there is a spiked ceiling falling down, the player must wait for it to touch the ground. When this happens, and Mario or Luigi Spin Jumps afterwards, his spin jump will sound like the ceiling hitting the floor.

The player must find a Fire Flower and Feather in purse (or vice versa), Yoshi and level with berries, like Yoshi's House. Now the player must drop the Fire Flower and let Cape Mario touch it and at the same time get Yoshi to eat the berry. This causes the game to freeze and as well make Mario flash from red to green like if he touched a Starman. It can also have a more helpful effect of infinitely raising the player's coins, giving the player up to 99 lives in the process. Then the player can leave the level by pausing the game and pressing, although this requires the player to have cleared the level before.

This is a glitch in Vanilla Dome 2. Mario must be Super, Cape, or Fire Mario. The P-Switch must be active; when the player sees a rectangle-shaped structure of coins sitting on the ground, Mario/Luigi must duck while running, and wait for the P-Switch to become inactive. After that, he must stop ducking. He will be in the floor. Even more worth noting, Yoshi and any grabable items will slide and will not react to gravity. This glitch is not possible in the GBA remake.

In Vanilla Dome 2, it's possible to fall through the floor via a glitch. Towards the end, the player has to take a left and go through the "secret" passage. Then the player has to get a Buzzy Beetle shell and toss it at the first two blocks. Then the player has to quickly get a running start and slide under the blocks before they harden. Once there, the player must not release the button. Once the player is completely surrounded, if the player presses, Mario will Spin Jump through the floor, leading to his demise. This glitch is still possible in the Game Boy Advance remake.

In any level with a pipe that extends and retracts into the ground, the player must get an item that Mario can carry around (Koopa Shells, P-Switches, etc.) and drop it on the pipe. When the pipe retracts, the item falls normally, however, when the pipe extends, the item gets stuck in the pipe. The item "vibrates" back and forth and eventually move out of the pipe after a few seconds. Yoshi can also be in the pipe, as long as Mario isn't riding him.

In a level with a P-Switch, the player can dash to the direction of a wall holding a P-Switch. To do the glitch, Mario must throw the P-Switch and swiftly dash to the wall. Mario gets stuck between the wall and the P-Switch and starts to shake. The player can get Mario out of there by jumping or grabbing the P-Switch.

In some of the underground levels, it's possible to walk through the floor to the exit. First the player must grab a Koopa Shell or flipped Buzzy Beetle, then move between platforms that can defeat Mario almost closed in. The player must jump on it and Mario is able to walk through the ground until they reach an area requiring a jump.

The player must place a Yoshi on an extending and retracting pipe. Whenever the pipe moves, Yoshi moves blocky.

If the player has Yoshi grab a berry on his tongue while it is extending, and then the tongue later attaches to an enemy in the same motion, the berry will be left where the enemy was, without being swallowed. The berry will also lack animation, but can still be eaten. In some cases, the berry will actually change color (and behavior). For example, on Funky, the first green berry (after being moved) will sometimes turn into a red berry if Yoshi eats the nearby Jumping Piranha Plant.

In the level Chocolate Island 5, if Mario/Luigi grabs the two P-Switches (how to do it can be read here) and bash the Yoshi block with it, the block will create two Yoshis, but only one appears. When the Yoshi falls into an abyss, the other one appears. If the player falls into an abyss and waits until Mario and Yoshi disappear while jumping, he is riding on an invisible Yoshi.

By throwing an enemy or object at a block very close to it, the block can be duplicated near it, unveiling the item, leaving the original block untouched. This can be done to either side of the block, above it, or above-diagonally to either side.

Also the game differentiates certain items by the block's horizontal position in the level. For example, blue P-Switches and gray P-Switches are actually the same object, but determined by an odd/even horizontal position of the block which contains it. Thus, by duplicating a block to the side with a P-Switch inside, it will give a P-Switch of the other color.

The player must shoot a fireball at a Lakitu who is riding in a cloud, and then make sure to collect the coin. The player must then jump in his cloud and it will last forever.

If the player takes a Grab Block and go through any pipe, it will never disappear. The player can take any carryable enemy (like Round Goomba) through a pipe and it will never jump on Mario, and a Bob-omb will never explode. If done with a Buzzy Beetle shell, it will be colored gray, not blue.

If two things (like P-Switches, Shells [two shells doesn't work], Spring, etc.) are placed in the same place and Mario/Luigi runs (pressing without dropping), he will catch the two things, then crouch and slide to grab the objects (the cause of dropping not  button), the player will take the two things at the same time.

This requires precise timing. If Mario or Luigi spin jumps at just the right time while a pillar is falling in a castle, he'll be inside the pillar.

Mario or Luigi must go to a level with a Super Mushroom in the Item Stock until the Giant Gate. The player must drop the item and wait it to go through the gate, and, after it is in the other side, finish the level. If Mario walks before the screen changes, he collects the Power-Up.

This glitch can be only done in the GBA remake of the game.

The player must simultaneously press a button and. The player, if done correctly, the status screen is shown. The player now has to choose a level. The character must move in an incorrect way going to an incorrect level. Pressing will result in no response, an endless Bonus Game, occasionally an actual level or, always occasionally, an unused level such as the unused "#2 MORTON'S PLAINS" (although there will be blank text as name) that will glitch the game drastically if the normal exit is taken or revert back to the original overworld if the secret exit is taken and the 97 exits are opened.

The player must take a grey P-Switch and go into the pipe. Though the P-Switch still grey, it acts like a blue P-Switch.

To get this glitch to work correctly, the player must be riding Yoshi. Yoshi must press the P-Switch and eat it before it disappears. When Yoshi spits it out, the P-Switch will be back to normal and the player is able to press it again.

This is a very simple glitch that is easy to do in various levels of Vanilla Dome. If Mario or Luigi throws a Koopa Troopa or Buzzy Beetle shell while on a very steep slope and faces the slope, it is not be able to climb it, so it goes right through it.

If Mario or Luigi loses a life above a Wiggler, he will stomp it, and even gain points, on his way off-screen.

The player must bring Cape Mario to an area with at least two Wigglers (three is better); the best place is Forest of Illusion 1, and jump on the yellow Wigglers to make them angry, and float back and forth so that the angry Wigglers are calm again. The player needs to keep jumping on the Wigglers, and the player will gain points as usual. After the player gets 8,000 points, they will get a 1-Up, 2-Up, and then a 3-Up. On the next bounce, the game will display strange symbols that represent five extra lives. More glitchy graphics will appear and they will give large amounts of points in addition to numerous coins.

This glitch was fixed in the Game Boy Advance version.

Ludwig/Roy/Morton Jr. Cheat
Ludwig Von Koopa is normally defeated by being jumped on three times or hit with 12 fireballs. However, he unintentionally can also be jumped on once and hit with eleven fireballs, or, more notably, hit with two fireballs and jumped on once. Do note this also works in Roy Koopa and Morton Koopa Jr.
