New Super Mario Bros./World 4

To unlock this world, you must beat the boss of World 2-Castle as Mini Mario. In these levels, do not fall in the water as it is poisonous.

World 4-1

Head right and you will pass a lot of spiders. Dash and jump to grab the first Star Coin, or jump on the spiders to grab it. Jump onto the blue dinosaur-like creature and let it carry you. Jump onto the first platform of blocks you see and then jump for the second Star Coin when the blue dinosaur-like creature is beneath it. For the alternate exit, when you see a platform of five blocks, jump onto it. Head to the middle of it and jump up to reveal a secret block. Climb the vine and go in the pipe. Finish the level to unlock a Green Mushroom Shop. Otherwise, continue the level. At one point, you will see the third Star Coin. Remove the spiders and then run across the yellow blocks to grab it. Jump quickly onto land to avoid falling in the water.

World 4-2

When you see purple and orange mushrooms, be careful as they bend on whatever side you are. Head right until you see the first Star Coin. Wall-Jump to it (or use the blocks). For the second Star Coin, let the mushroom bend so that you can grab it and then jump quickly to the flat green mushroom or you can pick up the red turtle and throw it at the Star coin( throw it from the green mushroom) . For the third Star Coin, go to the area with one glossy block and five coins a bit beneath it. Hit the block from underneath and then climb the vine. Climb the clouds and hit the block from underneath. Climb the new vine and jump for the third Star Coin. Then head down the green warp pipe and finish the level.

World 4-3

Head down the green warp pipe to start this underwater level. Beware of the big eels. For the first, stay near the bottom of the level. Quickly go grab the first Star Coin before an eel gets in the way and then stay near the top. Then move down to avoid the next one. Grab the second Star Coin when you see it and then continue. For the third Star Coin, wait as long as you can to hit the switch. Then hurry to the green warp pipe located after the second yellow pipe (it is right next to it). Grab the third Star Coin and leave by the green warp pipe. Head to the top and continue. Head up the green warp pipe at the end and finish the level.

World 4-Tower

In this level, you must hurry to avoid rising lava. Again, press the up arrow to grab a grid and jumping still works. Climb up and go through the door. Hit a switch (with Dash) as early as you can to go in the background while on grids. Keep to the left and you will see the first Star Coin. Grab it, then hit a switch to return to the forefront. Keep as much to the right as you can to grab the second Star Coin, then go left and up. When you get back to the grids, go right to grab the third Star Coin. Keep going up to reach the double doors and Bowser Jr. To defeat him, throw his shells back to him three times.

World 4-A

To cross the waters, stand on the rotating platforms. Depending on what side you're on, they will turn that way. Head right and jump when you see the first Star Coin to grab it. At the next water, jump onto the Green Paratroopa to reach the vine. Swing yourself to the right and go through the green warp pipe. Here you will find the second Star Coin. Leave through the warp pipe on the right. Head right, but be careful of the Piranha Plants. Head down the left green warp pipe in the pipe trio. Wall-jump to grab the third Star Coin and come back out through the third pipe. Finish the level by going through the pipe at the end.

World 4-4

On this next level, no you're not crazy. Caterpillars cannot be killed by being jumped on or hit with fireballs, but if you are a turtle or a turtle is thrown at them they will die. Head right and fall into the "cave" to reach the first Star Coin. Come back out by wall-jumping. Continue and hit the blocks you see from underneath to reveal a vine. Climb it and go left. Jump up slightly to the left of the ?-Block to reveal another vine. Climb and jump for the second Star Coin. Continue to the right and grab the shell of a Koopa and carry it to the mini pipes. Drop it to the left to grab the third Star Coin. Finish the level by continuing over the green pipes and go through the yellow pipe.

World 4-Ghost House

Head right through the door. Hit the switch and jump onto one of the blocks. You will be pulled up with them. Head right and grab the first Star Coin, then stand on the disc to be carried over to the next section. Go up, hit the red switch and go through the door. Go to the left, hit the new red switch, and wall-jump up between the red walls to the second Star Coin. For the third Star Coin, you need to be Mini Mario (using a Mini Mushroom). Go back down on the left, hit the red switch again, and head right. Stand on the pipe, and wall-jump to the right to get on the platform. Head up by wall-jumping and grab the third Star Coin. For the alternate exit to World 4-Cannon, head through the door. Otherwise, go back down, hit the red switch once again, but this time go through the green warp pipe. Climb up on the left, go right, and then go through the door to reach the end of the level.

World 4-Cannon

Enter the cannon to be transported to World 7. This level is highly recommended since you avoid having to beat the boss of World 5-Castle as Mini Mario.

World 4-5

Head right. To continue in this level, hit one of the bob-ombs so that it will destroy the blocks in your way. (You can move it if needed). Continue, and when you see the first Star Coin, repeat what you did with the bob-ombs to destroy the wall between you and the coin. For the second, hit the block underneath a bob-omb to set it off. When the blocks are gone and the ramp is up, jump up or wall-jump to the second Star Coin. When you reach the pipe with blocks over it, drop a bob-omb there and go down the green warp pipe once it is unblocked. Grab the third Star Coin, get out through the pipe on the right, and finish the level.

World 4-6

Again, climb on the blue dinosaur-thing. At the first sight of land, jump on it and grab the first Star Coin. When you see the first pipe, climb on land and wait for the blue dinosaur-thing to reach the other side before climbing back on. Jump on the switch and grab the second Star Coin. Hit the red switch and climb in the green warp pipe. Run and jump to grab the third Star Coin. Exit through the pipe on th right and finish the level.

World 4-Castle

When you see the first Star Coin, go back to the last swing and jump off at its highest point to reach it and grab it. Go right and wall-jump up to avoid the falling spike block. When you reach the big one, wait for it to destroy the three rows of blocks and let yourself fall down to grab the second Star Coin. Come back up ad continue to the right. On the first swing, let your self fall on the third Star Coin and jump back on. Go through the double door to meet the boss, a giant Goomba. To defeat him, hit the switch and go onto green platform. When he comes near, jump above him and do a ground pound. Do this three times to defeat him. However, if you are mini Mario, it is hard - if it is possible!
