Spaz Mario
                       After you defeat Bowser, and before the Princess floats down, press and hold Up until you see the credits. During
                       the walk back to Yoshi's House, Mario will flap his arms and look up and down. Wacky.

                       Exit level
                       In a level that you've already finished, press Start to pause and then press Select to go back to the Map Screen.

                       Re-enter Castles and Fortresses
                       On the map screen, stand on a defeated castle or fortress, and press L and R simultaneously to re-enter it.
 
 

                       Negative gravity
                       With Yoshi, you can slide uphill! While on a hill, just press diagonally down and either left or right, and he will slide
                       in either direction.

                       5 for 5
                       Sometimes you'll come across vertical chambers with five platforms, each with three ? Blocks on them (the first one
                       in the game is found up the first pipe in Donut Plains 1). Two Coins, and one 1-Up are placed randomly in the ?
                       Blocks for each platform. If you don't hit the block containing the 1-Up last, the blocks will "expire" and you won't get
                       the 1-Up. However, if you're Caped Mario, you can get the 1-Up each and every time. Starting from the left, spin-jump
                       and smack the lower-left corner of each block with your cape. The last block in each platform will always yield a
                       1-Up!

                       Recycle P-Switches
                       Stomp a P-Switch, then quickly have Yoshi eat the bottom. Spit it out, and the switch will be restored! With this
                       method, you can reuse the P-Switch as many times as you like.

                       Close encounter
                       If Mario stands one block-width away from a solid object and kicks a shell at it, the shell will ricochet off the object
                       and pass through Mario without causing injury.

                       Cool lava
                       Vertical walls of lava are harmless. Experiment in Vanilla Dome 3.

 
                       If you carry a Key or a baby Yoshi through the Goalposts, you will get a 1-Up Mushroom.

                       Two for the price of one
                       If you put two items down on almost the exact same space, you can pick both items up at once by holding X or Y
                       as you walk into them. You can throw both items up at a block that contains a item, and you'll get two of them! Or
                       pass through the Goalposts, and you'll get rewarded for both items.

                       Carry-on
                       Put an item down where Yoshi is standing. Hold X or Y as you jump onto Yoshi. If the item was in the right spot,
                       you'll now be carrying the item while riding Yoshi!

                       Quick points
                       Either be Fiery Mario with a Cape Feather in reserve, or Caped Mario with a Fire Flower in reserve. Find a high
                       platform, get direcly under your item reserve box, and keep pressing Select. You'll get 1000 points every time you
                       get the Cape Feather.

                       Multiple 1-Ups
                       For each enemy you stomp without touching the ground, you'll earn more and more points, and eventually 1-Ups.
                       The score for each enemy stomped will be: 100, 200, 400, 800, 1000, 2000, 4000, 8000, then 1-Ups for each enemy
                       thereafter. Remember: Fences and vines don't count as ground!
                       Similarly, when you kill enemies with a Shell, from invincibility, or when you go through Goalposts, the score for
                       each enemy increases the same way. But when you activate a Gray P-Switch, Gray Coins collected will increase up
                       to 8000 points, then a 1-Up, a 2-Up, and 3-Ups for any more you get.

                       Mega 1-Ups: Vanilla Secret 2
                       Get the Gray P-Switch from the second block by those Spinys, and take it back to the Midway Gate. Stomp it, and
                       run to the left. All those Winged Koopa Troopas from the beginning become Gray Coins! Getting over 50 extra lives
                       at once in this level is not uncommon.

                       Firepower
                       Mario's fireballs can take out three Koopa Kids: Morton, Ludwig, and Roy. This kills them nice and fast...

                       Memories...
                       Stay on the Special World map screen for a while, and eventually a steel-drum version of the famous Super Mario
                       Bros. theme will play.

                       The magic number
                       For an extra 1-Up at the Goalposts, match the the tens and ones digits of the time remaining to the tens digit of the
                       number of stars you got from breaking the tape.
                       Example #1: 133 left on timer, and 30 stars from the Goalposts.
                       Example #2: 200 left on timer, and 4 stars (equivalent to 04 stars) from the Goalposts.

                       Eight it up
                       When you get 100 stars total from breaking the tape at the Goalposts, you'll enter a bonus game. Look at the item
                       that's in the middle, and keep pressing Start to see what spot that item comes up on the other blocks. Then go to
                       that spot, and when the blocks come directly above you, jump. You'll get the item you want every time, and eight
                       1-Ups every game!

                       Coin formations
                       Some groups of Coins take the shape of arrows; follow them!
                       The Coins at the end of Funky spell: YOU ARE A SUPER PLAYER!!
