Super Mario Bros. 3/World 1

This is the Plains World. The levels are pretty straightforward and should not pose too much of a difficulty. Interestingly enough, you can beat 4 levels and make it to the final World right from the first World.

1-1
You will start the level with two sets of two item blocks and a Goomba in front of you. The top right one contains a mushroom. Proceed over the pipe and you will find a Koopa Troopa. Jump on it once, then kick it to the right to hit the block containing a leaf. Kill the next three Goombas. Now, there are two routes:

Route 1 (Raccoon Mario necessary)
If you are Racoon Mario, collect speed and fly where a trail of 4 coins lead you. You will find a platform of clouds with a block that contains a 1up mushroom. There are two pipes at the very end of the level. Collect speed on the platform of clouds and fly to the right. Land on the top of the top pipe to access a secret room with a big "3" spelled out in coins.

Route 2
Continue to the right and you'll see Koopa Paratroopas. If you're Raccoon Mario and you're really skilled with them, you can stomp on them several times without touching the ground and get 1-Ups.

Finishing this level with a coin number a multiple of 11 and the tens digit of the point count the same digit (for example, 0001120 points and 22 coins) with an even number of seconds on the clock unlocks the ghost coin ship.

1-2
Early in this level, there is a pipe with Goombas coming out of it. Raccoon Mario can touch 9 or more of them without touching the ground and get 1-ups. There is a 1-up on top of the pipe in the middle of the level that takes you to the secret room. To get it, jump up on the pipe. The secret 1-up block is above the pipe on the right side. Entering the pipe will take you to a coin room. After exiting the coin room, it will take you back a little, and now you can collect the coins without getting a P-switch. Near the end of the level is another pipe with Goombas coming out of it. There is a Paragoomba that drops microgoombas near the exit, so watch out for that.

1-3
At the start of the level there is a Boomerang Brother. You can knock it out with the Green Koopa before it.

Right after that, there is a small mass of breakable blocks. Kick the Red Koopa at the Music Block, that will clear it out. There is a mushroom/leaf in one of the blocks on the bottom, and 10 coins in one on the top.

Coin Heaven Route
There is a concealed pink music block in the small mass of blocks. reveal it, jump on it, and you will be taken to an auto-scrolling place called coin heaven. in addition to this, when you get to the halfway point of coin heaven, fly up (If you are Racoon Mario,) and get the 1up mushroom in the box. drop back down and go down the pipe, you will end up near the exit. Proceed right and finish the level.

Normal Route
from the mass of blocks, go right. you will see 4 columns of wooden blocks, one of which is only three blocks tall. bump the top block for a mushroom/leaf. There is a Boomerang Brother later, and the rest is straignt forward. Unless, that is, you want to get a warp whistle. proceed right, and you will notice a white block. Clear it off (enimies wise,) then duck on top of it for 3 seconds or so, until you fall behind the scenery. Now just run to the end of the level. You'll go behind the exit, and to a secret toad house with a warp whistle.

It is possible to combine these routes by completing the Coin Heaven Route and then backtracking to the white block to get the warp whistle.

1-4
The first auto-scrolling level of the game! This level has you jumping from block to block to reach the exit. Racoon Mario is recomended! Everything is strait forward in this level, but there are a few items hiding in these blocks. Only a few seconds into the level, you will notice there is a two-block platform with a four-block platform hovering over it. Stand on the two blocks, and hit the third block in the four block expanse. You will find a 1up. make sure to stand on the second block in the two block expanse, so the 1up moves towards you. After that, there are three L shaped masses of block. in the lower right block of the third L, there is a mushroom/leaf. You may notice the Red Koopa on the platform above you. jump on in, then pick it up. Now go jump up to the next group of blocks. Kick the koopa you're holding at the block sticking out of the platform, there is a 1up in there.

The White Mushroom House
If you grab all the coins in this level, a white mushroom house will apear in the screen. Most of the coins you can see, but alot are hidden in blocks. Remember that Mushroom/leaf that you found in the L shaped block group? Well the block just over to the right has 10 coins in it, if you hit it in sucession. Work fast though, before the block scrolls off the screen, and you're pushed off the edge. Later on in the level, you may notice an 8-coin high column of coins. get those by standing on one of those floating wooden platforms, then falling to get all of them, then jumping up to that L shaped mass of blocks. stay on the top of that L, and quick, start jumping! If you are not Small Mario, you will break the block above you, then start getting coins out of the one on top of it. hurry and get them all before it scrolls away, and the rest is easy. The white mushroom house will contain a P-Wing.

After entering the pipe, a Boomerang Brother will be on your left. Stomp on it, and then get to the Goal Panel. Note that it is hard to get a star in this level because of the short distance between the Pipe and the Goal Panel.

Fortress
This fortress has 2 new kinds of enemies, podoboos, which are fireballs coming out of lava, and Rotodiscs, which circle around, and which you're going to have to be careful passing. At the far right there is a door, an item box, and a boney turtle enemy. Knock out the turtle and run to the far right of the level. Maintaining your P-meter, run to the left.

Whistle route
One of the warp whistles is obtained in this level. To get this you have to have a flying leaf. If you have a full P-meter, take off and fly to the left of the wall and fly right until you start moving right. Go all the way to the right and enter a secret door to be transported to a room in the fortress with an chest. The chest contains the warp whistle. If you take this route, it will destroy the fortress, but it will not open the lock.

Regular route
Alternately, if you don't want the whistle, enter the door at the right of the wall and you'll be in a room with a spiked ceiling that will come down to crush you. Follow until the door at the end is reached, and enter it to see Boom Boom. Stomp on his head 3 times and the fortress will be destroyed and a lock will open.

1-5
This is an underground level. You begin by sliding down and killing 4 Buzzies. After a while, there is a pink block similar to that in 1-3. See the above section in 1-3 for how to do the coin heaven; the layout is the same. After returning from coin heaven, go down and follow all the way to the right. Exit the pipe and get the card.

1-6
Raccoon Mario can fly over and get coins just about halfway through the level.

Airship
This is the first Airship. Just before getting onto it, you'll see that the king has been transformed into a dog. The enemies are Bullet Bills and Cannonballs. Follow it and enter the pipe at the end and kill Larry Koopa by stomping on him 3 times. You can also use fireballs to defeat him (as long as you don't get hit, of course). You will get his wand and change the king back, and receive a message from Princess Toadstool containing a P-wing.
