Pikmin 3 Plus

Pikmin 3 Plus is a fan-made concept for an expanded port of, released in an alternate universe where was never made and Nintendo was instead more ambitious with porting Pikmin 3 to the Nintendo Switch. The game features an expanded Story Mode campaign, where each of the 4 main areas has had new parts added. The new sections of areas house 4 new bosses and 34 extra fruits, bringing the total number of bosses to 10 and the total number of fruits to 100. It also features new Mission Mode and Bingo Battle stages, as well as all the changes to controls and accessibility that Pikmin 3 Deluxe introduced.

Plot
The plot of Pikmin 3 Plus is the same as the plot of Pikmin 3, except after rescuing Louie from the Quaggled Mireclops, the Koppaites recieve a weak signal from the Tropical Wilds, Distant Tundra, and Twilight River, letting them know that there's more to find in each of those areas, but not where that thing to find is. The Formidable Oak is still unlocked, and the player can head to it and beat the game, or spend time in the other areas to collect more fruits. The source of these signals is a boss in these areas, and these 3 bosses can be defeated in any order. Each boss gives the Koppaites a crystal when defeated. If the Koppaites have all 3 crystals when they defeat the Plasm Wraith, the S.S. Drake's takeoff will fail and there will be a second final boss fight with a more powerful Plasm Wraith on top of the Formidable Oak. Defeating this boss leads to the true end of the game.

Area differences
Each of the 4 main areas of the game has changes made to add extra sections. Sometimes this involves minor changes to existing parts of areas in order to fit in these new sections. These extra sections feature rooms more oriented towards a specific type of Pikmin, particularly Blue Pikmin. This is to make each Pikmin type more useful beyond its initial introduction.

Garden of Hope
The does not receive significant changes in Pikmin 3 Plus, being the only area in the original game to already have 2 bosses. However, it does have some extra rooms added, some of them featuring more puzzles.

Tropical Wilds
The features significant expansion at its western end. Upon defeating the Sandbelching Meerslug, part of the sand wall at the back side of its arena collapses, allowing the player to walk up onto the beach behind. While there isn't much to find on the beach, there is much to find in the water behind the shoreline. There are several fruits in this Blue Pikmin-only area, and a boss fight that takes place fully underwater. There are other changes to the area, such as the Flighty Joustmite cave being replaced by a larger cave puzzle for Blue Pikmin and Winged Pikmin.

Distant Tundra
The features some more caves themed around ice. One of these caves features a large circular frozen lake, and an. Completing the electric circuit with Yellow Pikmin activates a heating element that melts the frozen lake, revealing a boss that sits in the water and shoots projectiles at the rest of the cave.

Twilight River
The features an extended river, taking the player into a third main sub-area with additional fruits to collect, puzzles to solve, and enemies to fight. There is a boss in an arena connected to this part of the area.

Formidable Oak
The has minimal changes, the only difference being the top of the area being turned into a boss arena at the start of the second final boss fight.
