World 1-3 (New Super Mario Bros. Wii)

World 1-3 is the third level in New Super Mario Bros. Wii. This is the first level to feature Yoshi, as well as Hammer Bros..

Layout
The level is set in a grassland like World 1-1, though much further away from Peach's Castle. There are platforms that use a similar design to the regular ground, but are lighter to indicate that they can be passed though. There will soon be a Hammer Bro. on a set of Brick Blocks above some Pipes stuck horizontally into the ground. The player will then find Yoshi for the first time. Yoshi can eat some fruits which when he eats five of this a item will be released. The first Star Coin is found right after, then there will be a set of three Koopa Troopas and six Goombas, which can be used to get an Extra Life. Next will be small Abyss followed by another block containing Yoshi Eggs, then two rows of blocks which a Hammer Bro. jumps on. The Checkpoint Flag is located after this, followed by the entrance to the second Star Coin. Outside the exit to the hidden area is a pipe with a Venus Fire Trap near the start of the cave,a few Goombas and two Koopas. Yoshi can be used to spit one of the fireballs to get up to three extra lives. The player must then continue down the course, past a few Hammer Bros, until Mario reaches the Flagpole and completes the level.

Star Coins

 * Star Coin 1: In clear view shortly after Yoshi is first found, the player will need to flutter jump or jump off Yoshi's back in mid air.
 * Star Coin 2: After the Checkpoint Flag, there will be three Warp Pipes with Piranha Plants. The player will need to stand on the lowest one and enter a hidden passage to the right to an underground tunnel.
 * Star Coin 3: Near the end of the level, the last Star Coin will need to be jumped up to by jumping off a nearby Warp Pipe.

Secret Exit
For the secret exit, the player should go back just a tad bit before the last Star Coin, just after the Venus Fire Trap. The player needs to jump to the high cliff edge leading to a hidden passage. Once the player reaches the entrance point, they need to jump over the passage, above the screen, and travel down the path following it. Near the end of this path will be a secret pipe, which will send the player to the secret Flagpole. The secret exit will take the player to the World 1 Warp Cannon, which sends them to World 5.
