Fed up of Koopa Troops giving you a hard time? Then read this handy guide that will sort you out.

 1-1 Stand 6 blocks away from the fourth pipe on this level and you can get a hidden 1-UP.

 1-2 Stan d on the big blue floating block about halfway through this level and smash the ceiling block to the
 right of it to make a hole. Now smash the block to the left of the hole and a 1-UP will appear and drop down
 the hole you made. The first pipe with a piranha plant in it holds a bonus room. Use the elevators at the end
 of the level to scroll off the top of the screen and head right. Now you will find a place called Warp Zone
 that will take you to worlds 2, 3 or 4. (Note: Warping to some places makes extra hidden 1-UPs appear!)

 1-4 After crossing the lava you will reach a tunnel of fire arms. Instead of stopping all the time, just sprint
 through them and you will emerge without a scratch. The Bowser is really a Goomba!!

 2-1 If you have warped here then the first pit with Koopa Troops in holds the much needed 1-UP. Later on,
 in a high block, there is a beanstalk that reaches for a coin loaded sky bonus.

 2-3 Only one thing can be said for this level... RUN!!! And don't stop until you reach the narrow platforms
 (take your time over these.)

 2-4 The tunnel of fire arms can be avoided again by running. The Bowser is really a Koopa Troopa!!

 3-1 When you reach two very short, high up platforms shaped like a =, use the spring board to leap over
 them and then jump into them from the right. If you try to use the springboard then you are more likely to
 fall to your death. Up there is a beanstalk to a lovely sky bonus. Also, keep bouncing off the Koopa on the
 final staircase to bag yourself many 1-UPs. Cool huh.

 3-2 After the second teeny tiny pit there should be a Koopa about to fall down it. Stop him and kick him to
 the right. Follow him so the shell stays on screen and, taking into account all the enemies it hits you should
 get a 1-UP.

 3-4 The Bowser is really a Buzzy Beetle!!

 4-1 Somewhere among the many block formations on this level, there is a 1-UP, but only if you warped to
 this level.

 4-2 When you have bypassed the goomba tunnel and the elevator you should see a small brick platform just
 a bit lower than the ceiling. Stand under the third one and jump to make a coin block appear, and then do
 the same with the second one. Jump up and hit the first block to make a vine appear. This will take you to a
 warp leading to worlds 6,7 and 8! That's not all. At the end of this level stand on the big pipe and smash
 your way into the ceiling and run right over the exit to find another Warp Zone to world 5!

 4-4 You need to take two routes to get out of this maze. Top route first, then hop down and edge left so you
 can take the bottom route. The Bowser is really a Spiny!!

 5-2 Bypass the first hammer brother and go don't go down the pipe to find a water land bonus. It is tricky
 and not worth it. Besides, there is a sky bonus instead not long after.

 5-3 This level look familiar? Of course it does. It's world 1-3 with lots of Bullet Bills and shorter moving
 platforms. It is still as easy and dull as the original.

 5-4 Another repeated level. This one is just world 2-4 with more fire arms and shorter moving platforms. The
 Bowser is really a Lakitu!!

 6-2 This level is a bonus goers dream world. Nearly every pipe holds a bonus room. There are also a fair
 share of vine worlds on this level (1) and also, lots of piranha plants.

 6-3 I have dubbed this level, 'Scary Bullet Bill Level'. They will try to knock you off the narrow and difficult to
 use platforms.

 6-4 Yes, another repeated level. 1-4 this time with yet more fire arms to deal with. Don't try and run
 through the first tunnel anymore. The Bowser is really a Bloober!!

 7-1 Time to cry, Bullet Bills and Hammer Bros. are in this level by the bucket load.

 7-2 Same as 2-2 except more Bloobers and more Cheep-Cheeps.

 7-3 Same as 2-3 except this one has Koopa Troopas to slow you down.

 7-4 Another maze level here. And the combination goes...

 Bottom route, Middle route, Top route, Top route, Middle route, Top route.

 The Bowser is really a Hammer Brother!!

 8-1 Time is of the essence here. If you don't move fast then you can run out of time quickly. There is a big
 hole in this level. You must do a running jump off the little stumpy bit of ground in the middle.

 8-2 Stand on the spring board and bounce up to make a 1-UP appear. Now head right, keeping it on screen
 and collect it at the end. To cross the big gap you must run off the pipe.

 8-3 This level is a funky castle. Try and get a fire flower, they really help against Hammer Bros.

 8-4 The last castle!!! Cross the lava pit by leaping from the bottom step, walk right, cross lava pit and go
 down the pipe directly after. Cross the next lava pit, kill the para-troopas and find the hidden coin block. Use
 it to go down the floating pipe. Avoid cheep-cheeps, cross the lava and go down the pipe directly after to
 find a water castle. Avoid the fire arms and go through the pipe. Kill the Hammer Brother and cross the lava
 pit to find Bowser. He is tough this time!!!

 And it can be said that Bowser is really Bowser this time!!
