World 2-5 (New Super Mario Bros. 2)
From the Super Mario Wiki
Mario begins on a platform. An orange platform covers the desert floor below which has a Chain Chomp. Several ? Blocks and Brick Blocks can be found, one of them releasing a Super Leaf. Another Chain Chomp can be found on a ledge further down the level. Another Chain Chomp can be found beside several Brick Blocks. Mario then should make his way up and to the right. Another long orange platform can be found over a pool of quicksand with a Chain Chomp on it. Several more ? Blocks and Brick Blocks can be found, followed by a Chain Chomp on a stone platform. This is followed by the checkpoint. Mario then reaches an area with stacks of yellow blocks with several Chain Chomps. After that area, more orange platforms follow, along with a Boomerang Bro. This is followed by another orange platform over two Chain Chomps with a Red Ring. Finally, another stack of yellow platforms can be found with a Boomerang Bro, followed by the Goal Pole.
