Tubular is the second level of the Special World in the game Super Mario World. This world is most notable for containing six Dragon Coins and is fairly linear. Many fans also acclaim this level to be the hardest in the game.
Tubular consists on a very large pit where the player must guide Mario or Luigi over it by grabbing numerous of P-Balloons. This can be difficult to do as there are numerous of enemies blocking the paths and moving around with the P-Balloon can prove a challenge. This stage can also be done with a Cape Feather but getting the gliding started up is even more difficult than completling the level normally. After reaching the Giant Gate, the player can access Way Cool.
An easier method to complete this level is to use a Blue Yoshi and swallow a shell, then fly to the exit while holding down / (to fly faster).
