Sky Move Lift
From the Super Mario Wiki, the Mario encyclopedia
Sky Move Lifts are airships appearing in New Super Mario Bros. 2. They constantly move to the right, and come with a deck with a one-block-wide gap, as well as a higher deck that acts as a semisolid platform. One appears in World 5-A and serves as the basis for the level, though another appears in the second level of the Gold Rush Pack that travels through water.
