World 2-2 (Super Mario Bros. 3)
From the Super Mario Wiki
The player starts at the bottom of a hill with a Goomba on it. Past the hill is some quicksand with a Venus Fire Trap in it. Past this is a Hard Block with a power-up inside, that can be collected by bumping into it, and a pipe over a pit, followed by more quicksand with a Venus Fire Trap. Afterward is an oasis, with a lift that moves across it and through Brick Block obstacles. Beyond the oasis is the Warp Pipe to the goal.
