List of Super Mario World glitches

These are the glitches found in Super Mario World.

Fast way to 9,999,990 points
Bring Cape Mario to an area with at least two Wigglers (three is better); the best place is Forest of Illusion 1. Jump on the yellow Wigglers to make them angry, and float back and forth so that the angry Wigglers are red again. 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 GBA version.

Glitchy graphics from defeated enemies
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.

Glitchy smoke
Go to Yoshi's House and keep pressing R and L. The smoke from Yoshi's fireplace will become glitchy.

Make grab blocks last indefinitely
Take a Grab Block and go through a pipe. It will never disappear. Similarly, the player can take Buzzy Beetles through pipes, and they will never reactivate.

Stuck Buzzy Beetle
When going to Donut Plains 2, pick up a Buzzy Beetle and go to the first platform going down. There, throw it upwards and leave it there. It will get stuck in the platform.

In the Pipe
In any level with a pipe that extends and retracts into the ground, the player should get an item that Mario can carry (Koopa Shells, P-Switches, etc.) and leave it on top of the pipe. When the pipe retracts, the item will fall with it as normal, but when the pipe extends, the item will be stuck inside the pipe. The item will "vibrate" back and forth and eventually move out of the pipe after a few seconds.

Freeze Glitch
In Super Mario World, there's a glitch that freezes the game. The player must find a Fire Flower first then a Feather (or vice versa). Have Mario become Cape Mario and then get Yoshi. Next go to a world that contains berries. 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 him/her up to 99 lives in the process. Then the player can leave the level by pausing the game and pressing Select, although this requires the player to have cleared the level before.

Note: This glitch will not work in the GBA remake.

Falling through the floor
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 down button. Once the player is completely surrounded, if he/she press A, he/she will Spin Jump through the floor, leading to Mario's demise.

Make items go through walls
This is only possible in the SMA remake. There are many parts in the game when Yoshi can eat an item and then stand right next to a wall and spit it out. For example, in Valley of Bowser 4, in the part when the player must smash through a row of blocks that has a trampoline near it, the player can swallow it with Yoshi, go down the small gap in the floor, turn left, and then spit the jumping board out. It is likely to go through the wall.

A Shell and a Pipe
In Vanilla Dome 3, the player has to go to the checkpoint near the two orange pipes. The player has to defeat the Beach Koopa and claim its shell. Then the player has to start from the right-hand pipe and take a running jump. The player has to try to aim about 2 blocks under the pipe's top and let go the shell the moment the player hits the pipe. If done correctly, the shell will be stuck in the pipe.

Ending Glitch
This glitch works in the SNES version and the GBA remake. Should the player go to Front Door or Back Door and defeat Bowser, the player should hold UP immediately after beating him. Continue holding UP until the credits screen appears. This will cause Mario to look up and down, waving his arms. He will continue to do this until Mario, Yoshi, and Princess Toadstool reach Yoshi's House.

Through a Hill
To do this glitch, the player must throw anything, such as a Buzzy Beetle shell, into a steep hill that they couldn't normally walk up and it will go through it and bounce around inside of the ground.

Stuck Buzzy Beetle 2
Go to Vanilla Dome 2. Make sure to have reached the checkpoint. Head to the left of the checkpoint and stomp on a Buzzy Beetle then go as far to the left as possible without pushing the P switch. Jump to the ceiling and throw the Buzzy Beetle up. It should be stuck in the wall.

Falling through the floor with Yoshi
Go to Vanilla Dome 2 and get a cape (it's just to the right of the checkpoint). Defeat the Charging Chucks. At the area where there are turning blocks near the ceiling, flip the top blocks and break the bottom blocks. Push Yoshi there. Crouch and jump on Yoshi. Mario/Luigi and Yoshi should fall through the floor.

?-block of death
The player must go to the steep slope after the first lava pit. A ?-block should fly toward the player. Crouch and hit it when it hits the slope. Mario/Luigi will fall through the floor making them lose a life.

Stuck Mushroom
Go to Chocolate Island 5. Near the start of the level there should be a structure with a ?-block. Bonk the block with the hidden mushroom. After it appears, bonk the rotating block to the left of it. The mushroom should be stuck in the wall.
