'''Tilted Tunnel''', or '''Acorn Plains-2''', is the second course of [[Acorn Plains]] in ''[[New Super Mario Bros. U]]''. It is an underground course with 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's flags.

The course is filled with slanted [[Warp Pipe]]s, which [[Piranha Plant]]s come out of, and shifting crystals, which move when the player gets to a specific point. Later in the course, there is a long pathway where the player can slide into [[Goomba]]s to gain [[Extra life|1-Ups]]. There is also a bonus area full of [[Buzzy Beetle]]s and a [[POW Block]]. The player can toss the POW Block to make a shower of coins fall down.

*'''Star Coin 1''': At the end of a long slide with [[Goomba]]s.

*'''Star Coin 2''': 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.

*'''Star Coin 3''': 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==

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 all the way across the last part of the cave section. There is a hidden Warp Pipe at the back. Getting to this secret exit unlocks [[Blooper's Secret Lair]].

*[[Koopa Troopa]]s (1 green, 3 red)

*[[Goomba]]s (16)

*[[Piranha Plant]]s (4)

*[[Buzzy Beetle]]s (3)
