World 4-2 (Super Mario Bros. 3)
From the Super Mario Wiki
The platforms in this level are continuously moving up and down, and a Cheep Cheep flies out of the water below. The player also encounters several other enemies like Piranhacus Giganticuses and Giant Koopas. To collect the power-up in the Giant ? Block, the player must kick an Ice Block into it. After two giant pipes and a bridge, if the player is powered-up, they can break the Brick Block underneath the ? Block to get a Starman, otherwise they will have to use a P-Switch nearby. In the same area, several Cheep Cheeps will begin jumping out of the water to attack the player. Entering the Warp Pipe at the end takes the player to the goal.
