Horror Manor is the third level Wario visits during the events of Wario World. It is the first level of Spooktastic World. This level has two major areas: the outside portion (a graveyard and a courtyard), and the inside portion (the mansion interior and its basement). The mansion interior is actually quite normal-looking, but the basement of the manor contains many electrical hazards, traps, and giant cogs. This level introduces Swirly Slabs, which appear only in this level and Beanstalk Way. Wario must use a Wild Swing-Ding to raise them upward and reach higher places. The basic enemies here are skeletal versions of the ones that appeared in the first two levels. Wario must fight Brawl Doll at the end of this stage.
Wario starts the level on a pathway leading to the north with some graves and dead trees to the left and a large abyss on the right. Up ahead, he encounters some small Skeletal Magons and the red Spriteling. After that, the pathway veers to the right and Wario is stopped by a Big Bone-Fist, which he must defeat to proceed. Further to the right are more small Skeletal Magons, some large ones, and the red button. From here, Wario approaches a fork in the road where he can either continue going to the right and progress toward the goal or go up a hill to the left and get more collectibles. Going up the hill takes him past some dead trees and the red treasure's spawn point and leads to a haunted Glue Globe that rises out of the ground repeatedly. Clinging to it allows Wario to reach a narrow ledge, and walking across it takes him to both the yellow button and the first trapdoor of the level, which houses both the first red diamond and the first Gold Statue fragment.
Back at the fork, the path to the right is narrow and features several small Skeletal Magons. At the end of this path, Wario is forced into battle with a yellow Gem-Bodied Creature. There is a Swirly Slab nearby which Wario can use to access a Gold Statue fragment by performing a Wild Swing-Ding on it. Up ahead is a graveyard with Skeletal Magons, statues, the yellow treasure's spawn point, and the second trapdoor. The sub-level within the trapdoor houses the yellow Spriteling alongside the red diamond. To the right of the graveyard are two paths, one going uphill and one going downhill. Most of the uphill path is blocked by a boarded door, but the chartreuse button is on the left side of the door and can be pressed from here. In order to take the downhill path, Wario must take down another Big Bone-Fist. Past the Big Bone-Fist are two Bone Cractyls and a Gold Statue fragment on top of a post, which can be obtained by using the nearby Swirly Slab. At the bottom of the hill is a puddle with some Swordfish in it and a steel trapdoor. From here, Wario can either go straight towards the manor ahead or begin ascending the nearby tower by climbing up the staircase.
At the top of the staircase is a Garlic Dispenser and a ladder that leads further up the tower. From there, going to the left takes Wario past some small Skeletal Magons and brings him to an area with a wooden chest and two haunted Glue Globes. The Glue Globe on the left leads to an area with three Bone Cractyls, the chartreuse treasure's spawn point, and a steel trapdoor, which contains the next Gold Statue part and red diamond. The Glue Globe on the left takes Wario to the next floor of the tower. Up here, there are small Skeletal Magons, spiked balls, and another haunted Glue Globe. The globe leads to the top of the tower, where the cyan button is. However, going up here also triggers a battle with a red Gem-Bodied Creature, so Wario must take it down if he wants to press the button.
The pathway to the manor leads past some small Skeletal Magons and Bony Triceratops. A Door Spirit blocks the way in; once it is defeated, Wario can enter the manor. The first room of the manor has an Enemy Generator and two haunted Glue Globes, both of which lead to the second floor. The green button can be accessed by climbing on some chains. The cyan treasure chest's spawn point is up here as well, in the center of two electrical hazards. On the left, there is another Door Spirit. Defeating it opens access to a series of balconies which lead to the green Spriteling. Alternatively, this Spriteling can be accessed by jumping off the top of the tower where the red Gem-Bodied Creature was fought, and the manor can be entered from there. On the right is yet another Door Spirit, and defeating it is necessary to make progress. On the other side of the Door Spirit is a corridor which houses the blue Spriteling and a Skeletal Ankiron. At the end of the corridor, the way into the next room is guarded by a Silver Door Spirit. The next room has a wooden trapdoor in it, as well as some Bone Cractyls and a staircase. The blue button is in the middle of the staircase. At the bottom, there is a wooden chest. There is a Silver Door Spirit to the left which guards a room with a big hole in the center. There is a Gold Statue fragment on the left side of this room, and dropping down the hole takes Wario into the basement.
Immediately upon entering the basement, Wario is placed in the middle of a Battle Ring. After fighting in the Battle Ring, there is nowhere to go but right, where there is a puddle with Swordfish in it, as well as some columns and a Garlic Dispenser. There is a Swirly Slab here which Wario must use to reach a nearby ledge. Up here is the green treasure's spawn point placed behind an electrical hazard and a haunted Glue Globe which will take Wario further up, where the path splits. The path to the left takes Wario past two large mechanisms with spikes on the bottom end that he must avoid, and there is a gap at the end that Wario should clear with a Corkscrew Conk to reach the ledge on the other side, where there is a wooden trapdoor. The next Gold Statue fragment is inside. The path to the right takes Wario down a ladder and into another puddle with Swordfish as well as one Bony Triceratops. On the upper-right corner is a wooden chest. There is also a steel trapdoor here which contains another Gold Statue fragment and red diamond.
At the back of this area is a wheel with Glue Globes on it, and clinging to one allows Wario to ascend upward, where there are two more Glue Globes, one leading to the left and the other to the right. The left path isn't useful at this point, so Wario should go to the right. Going south leads past two electrical hazards. From there, the blue treasure's spawn point is to the left, and some Bone Cractyls and a wooden chest are to the right. From here, if Wario jumps down, he will end up in a pit with two Enemy Generators. The pink button is at the upper-right corner of this pit. There is a Swirly Slab on the left that when raised, allows Wario to reach a ledge with a Skeletal Ankiron and a steel trapdoor, where the final red diamond and Gold Statue fragment are. By riding the Glue Globe wheel or cogs, Wario can reach a pair of chains with a platform in the middle, where the purple button is. The corresponding chest can be found by returning to the Glue Globe wheel and going to the left, dodging the electrical hazards on the way. Back by the cogs, continuing to the right takes Wario to a ledge with two pounding spike hazards; the purple Spriteling is between them. The pink treasure's spawn point is below this ledge, behind an electrical hazard. The goal trapdoor is further south. There is a set of Glue Globes to the right that lead to a Garlic Dispenser if the player wishes to replenish Wario's health before fighting the boss.
