After you beat all of the levels, you will go to the FORTY-NINTH level! There you will fight DK with giant barrels.

Fruit
Run into fruit on vines. The fruit will fall and will kill the enemies in its path.

Mario's Food Dreams
When you get a game over on a World, allow the game to idle for a few minutes. After awhile, Mario will fall asleep and mutter his favorite foods, such as ravioli, pasta, and others.
