World 8-1 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
At the beginning, a Bill Blaster shoots out Propeller Mushrooms, which are needed to get over the wall. Above are some Brick Blocks which block off six coins. There are three coins above the nearby Chain Chomp. The next section contains a Stretch and a Boo. Three coins are on both sides, as well as four above and seven in a V shape below. After this, the player finds two Brick Blocks and a ? Block containing either a Super Mushroom or a Propeller Mushroom depending on Mario's current form. Three coins are above and below this. The next part has two Flimsy Lifts with two coins below each of them and three coins and a Chain Chomp in the middle as well as four coins way up high. There is a Parabones to the right. Three coins are to the right of the Parabones. If the player goes up, they miss some things necessary for the challenges. The lower path has another V-shaped seven coins. This is followed by a Chain Chomp with three coins above. A 1-Up Mushroom is near here. A Stretch is found in the path above. When the paths combine, there is a ? Block with a Propeller Mushroom. After this is a Blue Lift, which takes the player down, and on both sides of the lift at separate heights are three coins and a Chain Chomp each. Two coins show the next jump needed. There is a Dry Bones near the coins. Then comes the same design with the Flimsy Lifts, except the Lifts are higher and the floor is a Conveyor Belts going to the Chain Chomp. The player then encounters two Brick Blocks with a ? Block containing either a Super Mushroom or a Propeller Mushroom depending on Mario's current form in the middle, with three coins above. Another Boo appears, and three coins are found below it. After this, more coins are found, along with a ? Block containing a 1-Up Mushroom above and to the right of these. After this, the player encounters two Flimsy Lifts with four coins below each one, a curved shaped for four Coins and a Big Chain Chomp. After this is the Goal Pole and the last two Coins are above it.
