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. It is an inside course with a part of it taking place in the shadows. It is unlocked by completing Conkdor Canyon, and its own completion unlocks Really Rolling Hills.
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 will have to navigate through an area full of Fuzzies, Piranha Plants, and one Big 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.
Luigi Sighting Edit
The player needs to use the Cat Suit to climb up the wall at the beginning of the stage to find a shadow of a 8-bit Super Luigi sprite crouching in the top left corner.
- Green Star 1: Shown in the shadows at the very beginning of the level.
- Green Star 2: Inside a Mystery Box guarded by Blurkers, the player has to hit the P-Switch to reveal a shadow of the Green Star.
- Green Star 3: 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.
- Under the ground during the shadow section, near the Big Piranha Plant. 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.
