Rugged Tundra

 The Rugged Tundra is the first area you play in Pikmin: Connection of the Worlds'' and serves as the tutorial level for the first two days. Red, Purple, and Cyan Pikmin are all found here. It consists of a snowy mountain, a freezing river and a frosty field, which mean ice-based enemies are a common find here. There is also a river flowing from the top of the level, which divides it into sections. Akou and Sasou (the main antagonists of the game) tried to make a base here, but as it was easily exposed to the public, they tried the Moon. That's why there's barely any enemies here (first few days). There are also 9 Treasures above ground.

Subareas
This area is split into seven subareas.

Subarea 1: Landing Site
This is the landing site of the area. Strange is that it eerily resembles the landing site from the from , only on a larger scale. To the west is the landing zone is the area where the President landed. Going even further west is a bridge that leads to an island in the nearby river (however, it is blocked by a paper bag that needs at least 40 Pikmin to crush it). On this island, you can see a bridge and a block of ice (behind this is another bridge).

Subarea 2: Frigid Fields
The bridge that goes left will lead you to the other side of the river. Here, off in the distance, you may be able to see some very tall grasses. To reach the Frosty Depths at the end of this subarea, you must delve into the seemingly never ending grass. As you voyage on, the grasses get taller and taller. They eventually get so tall that they fill the entirety of the camera's view. In the deeper sections, enemies hide, so figure out their attack patterns to evade them. At the very end is a clearing; that is where the Frosty Depths is located.

Subarea 3: Freezing Coastline
The bridge that goes right will lead you to the river's coastline. However, at first, it is blocked by ice, so you will need Cyan Pikmin to deal with the issue. The bridge will take you right to the coastline of the river! The beach is made of... cyan colored sand? It's not really just sand, rather, ice crystals mixed in with rocks and dirt. Sometimes it can get really windy here, so be sure to huddle your Pikmin close by or they'll get blown away. In the icy sand, sometimes enemies may hide, waiting to ambush you, so be observant. If you keep walking up north, you'll find the river's source...

Subarea 4: Arctic Springs
Soon, you find the river's source- cold, icy springs with water bubbling up. However, the water is coming out with great force, so find a switch to turn off the springs. You can walk around on the beach and explore. If you do so, and look at the center of the springs, you may realize there's an island in the center of it. On that island is the Frigid Cavern, a long, icy cave. A treasure is somewhere in the spring pool; use Cyan Pikmin to find it.

Subarea 5: Icy Slopes
The path leading right from the Landing Site will take you to a slope. However, at first, it is blocked off by a paper bag that needs 30 Purple Pikmin to crush. Behind it is the Bronze Mega Key. Anyway, if you keep going up, you'll find part of the icy river hindering your progress; again, there's an island in the middle of it. Throw some Yellow Pikmin up to it and they'll start building a bridge, which'll let you go further up. If you do so, you will then find yourself within a snowy maze of sorts. As you get closer towards the center, you'll notice a lot of scrap metal and frozen robots, as well as ice barricades. At the very center if the Icy Labyrinth. Keep going upwards to be at the coldest part of the whole area...

Subarea 6: Frostbite Ridge
You are now near the very top of the mountain, but you cannot go further. Here, it snows always and is very windy. If you swivel the camera to look back, you can faintly see the Landing Site- that is, if the clouds permit. You have to keep your Pikmin moving always, because if they stop moving, they could freeze and die. The Icicle Abyss, where you find the Cyan Pikmin, is here.

Final Subarea: Polar Grotto
If you continue upwards past the Icicle Abyss, go as high as you can and you'll see a waterfall. Underneath it are 3 random-colored 20-pellets! This is accessed by going all the way back to the beginning, where you might see a dent in the wall. That's the passageway leading to the Polar Grotto with the 20-pellets, but you need Brown Pikmin to make this tunnel. The pellets can regenerate about every 5 days, so check often! Just be careful, though: the floor here is very icy and slick, so your Pikmin could slide right off the edge.

Enemies

 * Snow Bulborb
 * Hairy Bulborb

Spring

 * Early Spring: Vast quantities of snow is still found everywhere.
 * Mid Spring: Changes start to happen: There are more sunnier days, it snows less, the snow starts to melt away, and hibernating animals wake up.
 * Late Spring: About half of the snow (at the base) has now disappeared. It is also warming up, contributing to the melting snow. It will now rain, too. Also, there are now a few puddles.

Summer

 * Early Summer: All the snow has disappeared, and it rains a lot, so much that the river will sometimes overflow, creating a flood. Still, it is gradually warming up.
 * Mid Summer: This is the hottest time of year. However, there is still a bunch of humidity in the air, so sometimes thunderstorms can form. Be careful!
 * Late Summer: It rains more, but it is starting to cool down.

Fall

 * Early Fall: Now, it starts to snow half of the time, and it is still cooling down.
 * Mid Fall: It is more cloudy, and most of the snow has come back. Some puddles freeze, and make icy, slippery surfaces. Some enemies go to hibernate.
 * Late Fall: Now the area is a winter-like landscape. It is very snowy.

Winter

 * Early Winter: Icicles have formed. If you walk underneath one, it will fall, creating a hazard to your Pikmin.
 * Mid Winter: It is very cold during this time of year. It snows violently, sometimes reducing your vision. This also poses a threat to Pikmin.
 * Late Winter: The weather has calmed down a bit. It is still very snowy.
