Greenhorn Forest

Greenhorn Forest is the first level of Wario World as well as the first level of Excitement Central. The stage is set in a forest, where basic enemies are fought and the mechanics of the game are explained. The collectibles are relatively easy to find as well.

Level layout
The level begins in a bushy area with some tree stumps. Shortly to the right is a climbable tree that leads to a wooden platform with some Magons and columns. The pink button and its corresponding chest are also on this ledge. To the right of the climbable tree is an imprisoned red Spriteling, who Wario automatically rescues. Ahead of the Spriteling are some tree stumps that Wario must jump over, leading to the first Gold Statue fragment. After that, Wario comes to an area with some Magons. Behind them is a climbable tree stump leading to another Gold Statue fragment. To the right are more Magons, along with the red button, its corresponding chest, and a wooden chest all right next to each other. Further ahead is an area with wooden platforms and climbable poles. Down below is another wooden chest as well as the yellow button. The yellow treasure's spawn point is up above on a wooden platform. Past the poles are more Magons, the yellow Spriteling, and a trapdoor leading to the first sub-level in the game, which houses both the first red diamond and a Gold Statue fragment.

To the right of the trapdoor is a Garlic Dispenser and an area with some Rock Blocks and another trapdoor. Inside the trapdoor is another red diamond and Gold Statue fragment. Beyond the blocks is the green treasure's spawn point and a Bunny Spring that leads to an area with the green Spriteling, a Triceratops, and the third trapdoor. To the left of the trapdoor is a wooden chest, and even further left is another Bunny Spring, which leads to area with some Cractyls and another trapdoor, which has another red diamond and Gold Statue fragment inside. Near the trapdoor is the chartreuse treasure's spawn point and a climbable tree. The climbable tree leads to two sets of wooden platforms. The platforms to the left have Magons, a Triceratops, and the chartreuse button. The platforms to the right lead to a Gold Statue fragment, some Magons, and the green button. If Wario drops down from where this button is, he will end up back by the third trapdoor.

Up ahead are some Magons and a Garlic Dispenser. Further ahead is a puddle with even more Magons and two large rocks. The rock on the left has a Gold Statue fragment hovering over it, while the rock on the right has a trapdoor on it. Behind the puddle is a wooden chest and a climbable tree which leads to a wooden platform with two Triceratops, two statues, and the cyan button. To the right of the puddle is a Bunny Spring which Wario can use to get over some fallen logs. Beyond the logs are some Cractyls, the cyan treasure chest, the purple treasure's spawn point, and the blue Spriteling. Behind a fallen log near the Spriteling is a trapdoor. Ahead are two bridges, but whichever bridge Wario tries to cross first will break, dropping him into Unithorn's Lair. However, it is possible to avoid falling with a well timed Corkscrew Conk. The bridges lead to an area with a Garlic Dispenser, the purple Spriteling, and the goal. As long as Wario has at least three red diamonds, he can remove the Stone Doohickey and fight the boss, but there are more collectibles beyond this area.

Past the goal, there are some Rock Blocks, the blue button, and a trapdoor. Further ahead are some Magons, a Triceratops, and a wooden chest. Behind the chest is a climbable tree which leads up to a half of a log laid out like a bridge. Wario can jump off of the log to land on a tall stump with the purple button. Going left from the half log leads to an area with Triceratops, Magons, and the final trapdoor, housing the final red diamond in the level as well the final Gold Statue fragment. To the left of this area is a thinner half log which leads to a wooden platform with Magons, an Ankiron, and the blue treasure's spawn point.

If Wario reenters the level after defeating the boss, there will be a set of ByeBye Balloons at the beginning that will take him to where the fourth trapdoor is.
