'''Tilted Tunnel''', or '''Acorn Plains-2''', is the second course of [[Acorn Plains]] in ''[[New Super Mario Bros. U]]''. It is an underground course that features slanted pipes and shifting crystals. It is the first course to feature the [[Fire Flower]] and to have a secret exit. It is unlocked via completion of [[Acorn Plains Way]], and its own completion unlocks [[Crushing-Cogs Tower]]. After this level is completed, a cutscene shows the flags on [[Peach's Castle]] being replaced by [[Bowser|Bowser's]] flags.

==Layout==
[[File:NSMBU Tilted Tunnel intro.png|thumb|left|The level's title card]]
The level begins next to a [[? Block]] containing a power-up, as well as a [[Warp Pipe]] leading underground. Some tilted Warp Pipes containing [[Piranha Plant]]s can be found, along with [[Goomba]]s. The cave splits into two paths, with the bottom path containing [[coin]]s and a [[Koopa Troopa]]. More Piranha Plants and Goombas are encountered in the top path, which leads to a group of shifting crystals. A section with more crystals follows, along with enemies such as Goombas and Piranha Plants. A sloped section with a row of Goombas is found, allowing the player to gain [[Extra life|1-Ups]]. Tilted Warp Pipes containing Piranha Plants are found, along with the [[Checkpoint Flag]]. This area features some [[Brick Block]]s, which can be [[Ground Pound]]ed to allow the player to reach an area with [[pit]]s and coins. More Piranha Plants in Warp Pipes are encountered, with a Warp Pipe that leads to a bonus area full of [[Buzzy Beetle]]s and a [[POW Block]], which can be used to make a shower of coins fall. More Koopa Troopas and Piranha Plants are encountered. A shifting crystal with a [[Red Ring]] above it is found, along with a Koopa Troopa and a Goomba. More crystals and Piranha Plants are found in the section, leading to a Warp Pipe. To the right of the Warp Pipe is a [[Hidden Block]] that leads to a hidden area with [[coin]]s. The Warp Pipe takes the player to the [[Goal Pole]].

Alternatively, the player can use a [[P-Acorn]] to fly up above the wall before the pipe leading underground, which will lead to the end of the level.

|At the end of a corridor full of slanted pipes, the player must use a [[Koopa Troopa|Koopa Shell]] to hit a [[Brick Block]]. The Brick Block contains a [[Beanstalk|vine]] that leads to a sub-area, in which the player can use the [[Pipe Cannon]] to get the second Star Coin.

|Once the player runs into two blue crystals, one with an Arrow Sign on it, the player must [[Ground Pound]] the latter crystal to reveal the path to the [[Warp Pipe]], which leads to the sub-area with the final Star Coin in it.

==Secret exit==
[[File:NSMBU Tilted Tunnel Secret Passage.png|thumb|300px|The path to the high ledge]]
Near the end of the course, there is a pink crystal with a [[Red Ring]] that shifts upwards. The player can use that crystal to jump up across the ceiling on top of the course. The player can then jump off a blue crystal to reach an even higher ledge. Now Mario has to run across the last part of the cave section. There is a hidden Warp Pipe at the back. Finding this secret exit will unlock [[Blooper's Secret Lair]].
