World 1-3 is the third course of World 1 in Super Mario 3D Land. It takes place in a valley high in the sky. The icon is a stone cliff with large wooden "steps" descending from it.
Mario starts on a rock. In this rock, a pair of binoculars can be used to see Toad above the right cliff (granting Mario a Star Medal). Ahead, in some wooden platforms there are two Piranha Plants and a Roulette Block. More platforms are found, each time lower, with Biddybuds, a Koopa Troopa and a Note Block. At one point, Mario finds a Mystery Box. Inside it, there is a purple room with three ? Blocks, two with a single coin and one with multiple coins. After Mario leave the Mystery Box, he faces with more Biddybuds and Para-Biddybuds. In the next area, Mario must ride a direction-change platform to cross a small cliff. In the other side, is positioned a Checkpoint Flag, Fire Piranha Plant and many trunks. Mario must go to the right, where a Super Note Block is found. Some clouds help Mario to traverse another cliff. Above them is a Red Ring. After, Mario jumps over a rock pillar. Jumping to a far below platform where Mario must ride another change-direction platform under some ? Blocks. The plumber must jump over Hard Blocks until he reaches near the place where some Biddybuds and the Goal Pole are located.
The UFO seen through the binoculars
- If Mario or Luigi looks into the binoculars at the beginning of the level and then wait long enough, a white UFO will appear in the sky only to move around for a bit and then fly up and out of sight.
