List of Super Mario World glitches

This is the glitches found in Super Mario World

Stuck Buzzy Beetle
When you go to Donut World 2 Pick up a buzzy beetle 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. 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 them up to 99 lives in the process. The the player can leave the level by pausing the game and pressing Select.

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 they press A, they will Spin Jump through the floor, leading to the 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.
