'''World 8-3''' is the fourth level of [[World 8 (New Super Mario Bros.)|World 8]] in ''[[New Super Mario Bros.]]'' It becomes accessible after completing {{World link|8|towern|World 8-Tower (New Super Mario Bros.)}}
==Layout==
This level is another underwater level, and contains the second and last appearance of [[Maw-Ray|Unagi]] and [[Mega Unagi]] in the game.

The player starts outside the main level, with a pipe taking them inside. In the very first section are two [[Bumper (Super Mario series)|Bumper]]s surrounding a [[? Block]] containing a Fire Flower. As the player swims upwards, they encounter various Unagi; some stay in place and lash out when the player gets near, and some travel horizontally. After passing through a group of Unagi and a [[Red Ring]], the level's [[Checkpoint Flag|midway point]] is reached rather early on.

After the midway point, a Mega Unagi is seen on the left side of the screen, and as soon as the player becomes level with it, it will chase after them. The Mega Unagi will chase the player through the rest of the level, and will destroy all [[Brick Block|brick]]s in its path; the player must swim quickly to avoid it, while also dodging regular Unagi, [[Cheep Cheep|Cheep-Cheep]]s, and Bumpers along the way. The player can use [[Jet Pipe|bubble-jet pipes]] to boost their speed and get farther away from the Mega Unagi.

If the player stops swimming, the Mega Unagi will stall with them. After a certain amount of time passes, the Mega Unagi will try to crouch down on the player, and then swim away offscreen. The Mega Unagi will not respawn as long as the player does not stall again (otherwise, the Mega Unagi will respawn after a minute), meaning the rest of the level will become much easier if the player survives.

At the end of the Mega Unagi chase section are two pipes; a green pipe on the lower end, and a red pipe above it. Both of these pipes will take the player to the [[Goal Pole|pole]], though the red pipe will allow the player to reach the top of it by stomping on a single [[Koopa Paratroopa]].

==Notes==
*This is the only underwater level that does not have its usual music, being replaced by the underground level's music to fit the darker theme of World 8.
