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-thingy 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-thingy is beneath it. For the alternate exit, hen 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. 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. 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 rab 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.
