Greenhorn Ruins

Greenhorn Ruins is the second level of Wario World as well as the second level of Excitement Central. This stage is, as the name implies, an old-looking building. Some other details include leafage and waterfalls. Here, Wario makes use of the Wild Swing-Ding move to turn Swirly Spinners and Glue Globes or chains to climb walls. This level introduces several elements that will recur throughout the game, such as enemy generators, Crystal Entities, Battle Rings, and most notably, steel trapdoors, which require a Piledriver to open and house vast, platform-centric, sky-based sub-levels, unlike the small underground rooms hidden beneath wooden trapdoors.

Level layout
Immediately upon entering the level, there is a Rock Block behind Wario which can be used to climb up to a higher ledge where the red treasure button sits. After hitting it, a treasure chest appears inside the Rock Block and can be obtained by breaking it. To the right are more Rock Blocks, and breaking them reveals both the yellow treasire button and the spawn point for its corresponding chest. Behind the blocks is a ladder that leads to an area with some small Magons and a pedestal with the red Spriteling on it. Further ahead are more Magons and the yellow Spriteling on another pedestal, as well as a wooden chest. Beyond the yellow Spriteling is a gate, which is operated by a Swirly Spinner. Wario must pick up one of the nearby Magons and perform a clockwise Wild Swing-Ding to turn the spinner and open the gate. The gate leads to a stairwell where the chartreuse treasure button can be found. At the top of the stairwell is an open area with some columns, a statue, and two Magon-spawning enemy generators. Further north is an area with three Triceratops and the first trapdoor in the level, which is also the first steel trapdoor. The sub-level beneath the trapdoor houses both the first red diamond and the first Gold Statue part of the level.

To the left of the trapdoor is a staircase which takes Wario to where the green Spriteling is. Near the Spriteling are some Magons and a set of Glue Globes which takes Wario to a higher level. After climbing the Glue Globes, Wario can simply proceed further into the level by continuing upward, but there is area to the left with more collectibles. This area has Magons, Cractyls, a Garlic Dispenser, and a wooden trapdoor. To the south are some narrow paths with small Magons on them which lead to the green treasure spawn point. Further south is the chartreuse treasure spawn point. Back by the Glue Globes, Wario can continue climbing upward to reach a climbable chain, which takes him even further up. This leads Wario to a circular arena where he is forced into a battle with a red Crystal Entity. After defeating it, Wario can climb down another set of chains to reach an area with some Magons and an Old Red-Mug. At the bottom-left corner of this small area is the green treasure button, and defeating the Old Red-Mug creates a shortcut back to the area where the corresponding chest spawns.

To the right of this area is a small pit with an arch of Glue Globes over it. If Wario falls into the pit, two Triceratops will spawn, but Wario can easily get out of the pit using a Glue Globe to the left. The arch of Glue Globes can be used to get over the pit while collecting a Gold Statue part in the process. From here, going to the right takes Wario to a stairway of sorts with platforms and Glue Globes which contains both the cyan treasure spawn point and a Garlic Dispenser. At the bottom of this section are some Magons and Triceratops. To the left is a Swirly Spinner, which opens a gate. Beyond the gate is an area with an enemy generator and some Glue Globes that lead to a Gold Statue part. The blue treasure button is at the bottom left of this area, and taking down the Old Red-Mug on the left creates a bridge to where the treasure chest spawns.

Back by the Swirly Spinner, there is a platform to the right with an Ankiron and the cyan treasure button, and to the right of those are some Rock Blocks which conceal a wooden trapdoor, which houses the fourth Gold Statue part. Near here, there are some Glue Globes which Wario can climb to reach another wooden trapdoor, the blue Spriteling, and the game's first Battle Ring. After fighting in the Battle Ring, Wario can proceed to the right and climb down a chain to reach an area with an enemy generator and a steel trapdoor, which holds another Gold Statue part. There is an Old Red-Mug on the right which blocks the path ahead; defeating it opens the way to the next part of this area, which has another enemy generator, a gate, and some Rock Blocks to the right. Climbing on the Rock Blocks allows Wario to reach an elevated platform where the purple treasure button is, and breaking the blocks reveals the pink treasure button and another steel trapdoor with a Gold Statue part inside.

In order to proceed, Wario must open the gate by turning the Swirly Spinner, exposing a ladder. After climbing it, there is a lone Glue Globe can be used to climb onto a platform with an Ankiron and a wooden trapdoor. There are Glue Globes on both the left and right sides of this platform; the one on the left takes Wario to the purple treasure's spawn point, while the ones on the right lead to a Garlic Dispenser, two Triceratops, small Magons, Cractyls, and the purple Spriteling. South of the Spriteling is the pink treasure's spawn point, and to the right is the goal point as well as a steel trapdoor housing the final red diamond and Gold Statue part.

If Wario reenters the level after defeating the boss, there will be a set of ByeBye Balloons at the beginning that will place him after the Triceratops pit with an arch of Glue Globes over it.
