The Ninja Attraction, also called the House of Tricky Ninjas, is a location in Paper Mario: The Origami King. It is a pretend ninja training facility at the Shogun Studios amusement park. There are 25 cutouts of ninja Toads hidden in the area, and finding them all earns Mario a prize. Luigi is encountered here, giving Mario the Shogun Studios Master Key.
The Ninja Attraction is visited during Mario, Bob-omb, and Olivia's first trip to Shogun Studios. Olivia encourages Mario to go in, while Bob-omb is scared and refuses to enter, claiming that he is "too mature" for it.
At the start of the Ninja Attraction, attendants are given an introduction speech and instructed to find the hidden ninja Toads. The doors then open, and to progress further, Mario must hammer the block of wood on the right to open up a narrow hallway with a sliding door. Entering this door leads to the first real area: a living quarters containing two closets, a chest, a table, and a lamp. To progress, Mario must pull up the poster in the back of the room, revealing a hidden exit.
The next room of the attraction has white tiles on the floor, which flip over and reveal Ninjis when Mario walks near them. To exit this area, Mario has to go to the far right of the room and hammer the wooden panel in the back, causing it to flip around. He can then walk left to pass through a garden area.
Inside the garden is a small hut that leads to the operation room behind the attraction. Two Toads are hidden here, and going downstairs leads Mario to Luigi, who is stuck in some gears. To get him down, Mario has to fill in a Not-Bottomless Hole, climb down a ladder to a smaller gear, and begin hammering it to move the other gears. Luigi falls out, but is still crumpled, so Mario must hammer him. He gives Mario the Shogun Studios Master Key, believing it to be the key to Peach's Castle. Once Olivia tells him he has found the wrong key, Luigi runs off to find the real key.
Going back to the garden and exiting left leads Mario to a room with hidden spikes popping up from the ground. The entrance to this room is also blocked off. To find the spikes, Mario can use his hammer, and he must navigate to the left of the room to hammer a wall panel open, then pull on a rope to reveal a staircase. Climbing up this staircase, Mario has to navigate to the south end of the room and then drop down to the exit, which is surrounded by spikes.
Next, Mario enters a room with a wall of cabinets. He has to destroy a wooden floor panel to cause the cabinets to descend in a staircase formation, and can climb it to be ambushed by Ninjis. This reveals a Magic Circle, and Mario can peel off a Thwomp's calm face to reveal an angry one. As the walls begin closing in, Mario has to run from a wave of Thwomps, landing on a slide that takes him to the exit of the attraction. If he has found all 25 Toad cutouts, he is rewarded with a Collectible Treasure; repeat runs give a Fire Hammer weapon instead.
