Super Bell Hill

Super Bell Hill, otherwise known as World 1-1, is the first course of Super Mario 3D World. Similarly to the World 1 map, the course takes place on grassy plains surrounded by water. Within the level, players can find grassy fields, small ponds, Bean Poles, and a white wooden bridge. It is unlocked from the beginning and its completion unlocks Koopa Troopa Cave.

Layout
The level starts on a grassy field, with a set of white stairs that leads to a Goomba and a ? Block. To the right is a Clear Pipe, which leads to an area full of Goombas and another ? Block. Afterwards, there is a second Clear Pipe that leads to another set of Goombas and a wall that can be climbed with a Cat suit, with a series of hills as an alternate path.

Following this area are two Clear Pipes, one of which brings the player to the Midway Point. This leads to a tree with a Super Bell, and a hill with a giant Rabbit that has a Mega Mushroom. Nearby is a pond with another smaller rabbit and a Warp Pipe. Past the pipe is a Cat Goomba, a series of Brick Blocks, and a white wooden bridge with stone blocks seen directly past it. A tunnel nearby contains wooden crates, and a passage under the bridge that has a 1-Up Mushroom. After this, a Clear Pipe leads the player to the Goal Pole.

Green Stars

 * Green Star 1: Near the beginning, players will find a Clear Pipe. Through the top route of the pipe, players will find the first Green Star.
 * Green Star 2: After the Midway Point, there is a Rabbit that circles around a small pond. When caught, it offers the second Green Star.
 * Green Star 3: The player needs to use the Mega Mushroom from a big Rabbit on a hill close to the Midway Point. The player must smash the stone Brick Blocks directly after the white bridge to reveal the third Green Star.

Stamp

 * The stamp is located between two Bell Trees near the midpoint lies a Warp Pipe that leads to a room containing the course's Stamp. The stamp is Cat Mario.

Luigi Sightings
After dropping out of the clear pipe near the halfway point, the player can visit a Sprixie with a pair of binoculars who will show them the direction of the goal. In this binocular view, it's possible to make out a tiny Luigi peeking over the fence across the yard to the right of the screen.
