Super Mario World Easter Eggs and Secrets (Wii)

Super Mario World is a platform game developed and published by Nintendo Co., Ltd. for the Super Famicom/Super Nintendo Entertainment System. In Japan, Super Mario World is also known as Super Mario Bros. 4 and it was one of the launch games for the system, along with Pilotwings and F-Zero. It was released on November 21, 1990 in Japan, August 13, 1991 in North America and then April 11, 1992 in Europe. The game was re-released for the Wii's Virtual Console in North America on February 5, 2007 for 800 Wii points. There were no changes from the original SNES version. This is a side-scroller as in previous Mario games, and it takes advantage of the Super Nintendo's 16-bit graphics and stereo sound.

Easter Eggs

Inverted World Map
Complete The secret world. (With Stage names Such as Awesome and Tubular.)
And then Enter the second Star road that Appears after you Complete "Funky" And the world Map will Have A different Color Pallete and some enemies will look different.

Glitches

Berry Freeze
Enter a level with Yoshi, Cape Mario, and a Fire Flower in reserve. Position yourself under a berry in a way that you can get the fire flower and get the berry at the same time. If you happen to eat the flower and the berry at the same time, the game will freeze. Several things have been reported while using this glitch. Sometimes when the game freezes, your coin count will rise until you quickly have 99 lives. Press Start and Select to exit the level. One person's game froze, horizontal lines appeared on the screen, and weird music kept looping over and over again. Then came a buzzing noise, and he was returned to the file select screen, with his file deleted. Thankfully, that's not normal. Even so, this is an interesting glitch to exploit every once in a while.

Use, but don't waste a switch
First all you need to do is find a switch ( the kind that changes the square outlines into brown blocks ). You also need to be on a Yoshi. Normally when you hit the switch, it will flatten and disappear. When you jump on it, quickly turn around and eat it with your Yoshi, if you do it fast enough, you will have it in the Yoshi's mouth. You can spit it out and use it again.

Secrets

Easy Extra Life
Beat a stage with your time ending in the same digit repeated twice as the tens place of your Star total, and you'll be awarded an extra life.

Example:

With 17 stars, beat the stage with your time ending in 11.

Hear SMB remix
If you sit at one of the levels in Special World for about 2 minutes, you'll start to hear a Super Mario Brothers remix!

Item Conversion at the Goal
Try holding an item (shell, trampoline, etc) and cross the Goal line. The item you're carrying will turn into a 1-Up mushroom.

Re-enter Castles you have already beaten
When you beat a castle you normally cannot enter it again. Go to the castle you want to play again and Press L+R at the same time.

Here's how the Wii version of this oldie but goldie looks like:
