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
To begin this level, Mario should jump into the middle Pipe, which will blast him into the air. Mario needs to grab onto the Metal Fence (the lowest one) and go to the left. Jump onto the next fence, avoid the Koopas, and jump to get the first Star Coin. Then, using the Pipe again, Mario should grab the highest metal fence. Mario should flip the fence (press X in 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 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.. All the player has to do is jump on him three times, while avoiding his spiky shell, to defeat him.

Star Coins

 * Star Coin 1 - Grab the lower fence and make your way to the left. Keep climbing upwards and the first coin will be there.
 * Star Coin 2 - When Mario or Luigi reach the area with the Amps, flip the gate. Before going onwards, go around the Amps and back to the left. Hit the gate again and continue upwards. In the upper left corner is the second Star Coin.
 * Star Coin 3 - Take the door to the upper right and hit the red switch. Travel up the fences and the last Star Coin is next to the exit.

Enemies

 * Amp
 * Koopa Troopa
 * Bowser Jr. (mini-boss)
