Pikipedia:Area article guidelines
The following policy applies to articles about areas in the series. The following sections should exist, with the names and order provided.
Opening text
The opening text (not a section) should describe what the area is like in the broadest terms possible, how the area is reached, what are the most important events that take place in it, and other basic points about the area. If it's a Pikmin area, it should also have a paragraph or two explaining the Challenge Mode version: the differences between it and the story mode variant, as well as the most notable gimmicks and exclusive features in the Challenge Mode version.
Overview
The first section in the article should have this name. It explains the geographical properties of the level, like its theme, the type and distribution of the terrain, the types of structures of interest (several tree stumps, several lakes, etc.), all in a general sense. It should also explain the disposition of the level: whether it is mostly square with equal exploration on all points, or if it's mostly linear, with clear start and end points, as well as if the area has several open regions or closed paths, and if said paths cross commonly or not.
Layout
This section should explain with more detail the sections of the area, including cardinal direction references. For example: "To the north, there is a large circular arena accessible at a higher ground level. The Armored Cannon Beetle here guards the Radiation Canopy, which resides on a small alcove in the arena." Use paragraph breaks generously, to make sure the text isn't hard to follow.
Caves
Only for Pikmin 2 areas, this section should list and link to the caves the area contains.
Objects
A section listing the objects that can be found here. It should follow the object listing policy.
Points of interest
This section should explain and list some of the more interesting and noteworthy points of the area. For instance, the large tree stump in The Impact Site would qualify, as it is a clearly delimited section of the area different from the remaining terrain, and also serves as an arena for two enemy battles.
Guide
Two or three broad guides should exist: a basic one, a speed one, and a Challenge Mode one, if applicable. The story mode guides explain how to "complete" the area, meaning discovering all Pikmin types within, collecting all collectibles (ship part, treasures, spacesuit upgrades, etc.), and clearing all caves. The guides shouldn't explain how to clear a cave, however.
The basic guide helps explain how to complete the area, and what requisites there are for each of the area's events. It should be placed under a section titled "Basic guide".
The speed guide should give an overview on the general order of events that need to be done in order to complete the area as quickly as possible. It should be placed under a section titled "Speed completion".
The Challenge Mode guide should provide a strategy on how to complete the area with the best score possible.
Pikmin drawings
For Pikmin 3 areas, this section should contain a gallery with screenshots of the Pikmin drawings, and their locations on the gallery's description.
Gallery
The gallery should contain some screenshots showing most of the points of interest and notable sections in the area, as well as link to a category containing more images of the level, by use of the template {{see more}} below the gallery. The gallery should also include the map shown on the infobox, because users that are not running Javascript won't be able to open the map using the infobox.
