World 3-Tower (New Super Mario Bros.)

 is the Tower level of World 3 in New Super Mario Bros. The Tower is reached after beating World 3-2, and beating this stage leads to World 3-3.

Layout
This level is a tower level that contains many fences and Climbing Koopas. To begin this level, Mario should jump into the middle Pipe Cannon, which will blast him into the air. Mario needs to grab onto the lowest metal fence, and then go to the left. Mario should jump onto the next fence, avoid the Climbing Koopas, and jump to get the first Star Coin. Then, using the Pipe Cannon again, Mario should grab the highest metal fence. Mario should flip the flip panel by punching the middle, and jump onto the next floor of the tower. The second Star Coin is obtained by going to the far left of the tower and jumping onto the metal fence above. The player can then go two ways: the left door, or the right door. The right door leads to the third Star Coin, and the left has another door that leads to coins, but both doors end up in the same place. Past the double doors is Bowser Jr. To defeat him, Mario must jump on him three times.

Star Coins

 * Star Coin 1 - Mario should grab the lower fence after being launched from the Pipe Cannon and make his way to the left. He should keep climbing upwards while avoiding Climbing Koopas and the first Star Coin will be there.
 * Star Coin 2 - When Mario reaches the area with the Amp, he should flip the flip panel. Before going onwards, he should go around the Amps and back to the left. Mario should then hit the flip panel again and continue upwards. In the upper left corner, Mario can find the second Star Coin.
 * Star Coin 3 - Mario should enter the door to the upper right and hit the red switch. He should travel up the fences and the last Star Coin is next to the exit.
