Secret Exit in World 7-6
After you reach the mid-level point you will meet an area with two rows of bricks. To do this trick you must be big but not mega mushroom sized. Heres what you have to do, knock out the middle brick on the top row then go on to knock out the third brick on the bottom row. This will make a vine grow, climb the vine then start making your way to the end of the level and reach the red flag. Hope this is helpful to all you's out there if you have any further questions or opinions - thoughts feel free to comment below and i'll try to get back to you ASAP (for anyone who does not know what ASAP means it means as soon as possible).
Bonus mushroom houses
When you get to the end of your game finish and land the timer on the same two digits at the end eg. 011,288 etc. When you land the last two digits on 11,22 or 33 it will reward you with the red mushroom house which you then go in and get a random item box. When you finish and get the timer on 44,55 or 66 it then gives you the green mushroom house which you go inside and get 1-ups. Stop the timer at 77,88 or 99 and you'll get a orange mushroom house which will award you with a mega mushroom.
Infinite 1-Ups in World 2-4
This is probably the easiest and fastest way to get infinite 1-Ups. First, just go through World 2-4 as you normally would, and stop when you get to the staircase at the very end of the level. Stand on the first (bottom) step of the stairs, and wait for the Koopa to come. As soon as the Koopa lands on the second step, jump. If this is timed right, you will keep bouncing on the shell and start getting 1-Ups. If you mess up, just walk to the left a good distance and when you come back to the staircase the Koopa will be back.
