Shadow-Play Alley, also known as World 2-3, is the ninth regular level and the third course of World 2 in Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury. It is an inside course with a part of it taking place in the shadows. It is unlocked by completing Conkdor Canyon, and completion of either this level or Puffprod Peaks unlocks Really Rolling Hills. Shadow-Play Alley also appears in the Wii U version of Captain Toad: Treasure Tracker as an extra stage if the player's Wii U has save data for Super Mario 3D World.

Layout

The course starts in an underground area with some Fuzzies and Piranha Plants. Some moving platforms and Fire Piranha Plants await, followed by the Checkpoint Flag. The next area is set in the shadows, where the player has to navigate through an area full of Fuzzies, Piranha Plants, and one Mega Piranha Plant until they reach the door leading them to another area. Here, the player must pass some enemies and moving platforms until they reach another door which leads them to the Goal Pole.

Collectables

Green Stars

	Shown in the shadows at the very beginning of the level.
	The player will see a Mystery Box guarded by Blurkers immediately after exiting the 2-D shadow section. For the challenge, the player must hit the P-Switch to reveal a shadow of the Green Star.
	Before the door exit, there's a hidden gap that reveals Captain Toad scared by the shadow of a wooden cutout of Bowser. The player has to knock it down then Captain Toad will give the third Green Star.

Stamp

	Under the ground during the shadow section, near the Big Piranha Plant (see picture above). To reach it, the player needs to be in Cat Form to claw the crates next to the stamp and reach it. The stamp is a Potted Piranha Plant.
