Hands-On Hall

Hands-On Hall, otherwise World 6-3, is the third level in the sixth world of Super Mario 3D World, becoming accessible after beating World 6-2, Spooky Seasick Wreck. Its own completion opens up Prince Bully Blockade. This level has a unique style combining both Japanese and Chinese features. It's one of the three courses that can only be played on the Control Pad.

Layout
The area Mario first visits is a short indoors corridor. At the end of it there are two shōji doors that reveal a Warp Pipe when tapped on via the Wii U GamePad. Going down it, the player is dropped into a longer, three-story room with a few Goombas, Galoombas and one single Spike. The third story has a gong that makes coins fall from the ceiling when hit.

A Warp Box takes Mario to the outside of the temple, where the Checkpoint Flag is, besides Propeller Boxes and enemies like Thwomps and Goombas. The Goal Pole is on the highest roof. Here, Mario can also collect all five Key Coins to open a Warp Box that leads to an optional area with many gongs and Spikes.

Green Stars

 * Green Star 1: Behind two touchable false walls, which in turn are behind doors on the third floor, alongside two Galoombas and piles of coins.
 * Green Star 2: Floating above a gap in the outdoors area, requiring the use of a Propeller Box.
 * Green Star 3: After the Warp Box in the optional room, there is a gong that reveals a Mystery Box. It warps Mario to a cage with a Spike. Defeating him makes the third Green Star appear.

Stamp

 * In the optional area, Mario must leave the building through a secret passage in front of the first set of Spikes. There, Mario must use a Propeller Box to fly up to the middle roof, where the course's Stamp is.

Enemies
