World 4-5 (Super Mario Bros. 3)
From the Super Mario Wiki
The player starts at the bottom of a pyramid made up of giant Empty Blocks, with a green Giant Koopa and a Colossal Koopa Paratroopa moving down it toward the player. On the other end of the pyramid is a big ? Block with a power-up, which the player has to knock a Koopa Shell into it or the big Brick Block underneath in order to collect. Afterward is a large pipe with a Piranhacus Giganticus in it followed by a trio of Turtle Cannons firing Bullet Bills and Missile Bills; in-between each pair is a set of three ? Blocks, the first holding a power-up. Next is a small platform with another Turtle Cannon and another pipe with a Piranhacus Giganticus that the player has to time their jump over. Located above the second Turtle Cannon afterward is a Brick Block that contains a beanstalk leading to a Warp Pipe high above, which leads to a secret room containing a Tanooki Suit and a Switch Block. Afterward are more Turtle Cannons and Piranha Plants before the Warp Pipe leading to the goal.
