World 8-1 is the first level of World 8 in New Super Mario Bros..
This level takes place in an outdoors haunted setting, with dead trees in the background. At the beginning of the level, a Splunkin and a Crowber are encountered. Another Splunkin is found on a ? Block containing a power-up, and is followed by a platform with two Bill Blasters on it. More Splunkins are found on a sloped portion of the ground with a Bill Blaster at the top. More Crowbers are encountered during a section of platforms with pits in between them. A spring is found in a ? Block over a pit. A Bill Blaster is found, followed by a Boo and some Splunkins. The midway point is found with a ? Block containing a power-up above it, along with a Boo and more Bill Blasters. After another Boo and some Bill Blasters, a Banzai Bill Cannon is found in front of the pole.
- Star Coin 1 - Mario must keep moving until there are two solid blocks, with a ? Block above them. Mario must then hit the ? Block to reveal a spring, place it on top of the higher solid blocks and jump on it, revealing a secret area with a Star Coin.
- Star Coin 2 - The next Star Coin is found next to several Bill Blasters and a Boo. Mario must avoid them and collect the Star Coin.
- Star Coin 3 - The last one is found next to a Banzai Bill Cannon, where Mario must collect it while avoiding the Banzai Bills fired from the Cannon.
