Bombroot Garden

The Bombroot Garden is the second cave in the Ice Blanket and the last mandatory cave in the game. Wild Orange Pikmin are found here, which are required to get the Orange Onion. It is found in the center of a circular garden filled entirely with Bashful Bombroots.

When the cave is first approached, a cutscene begins. Rhea is immensely exasperated upon seeing these Bombroots. She complains about how hazardous they are and how miserable this cave is going to be because of it. She wishes out loud that there was a method of handling them.

Upon landing on the first sublevel, the Bombroot Garden gives the player a warm welcome by immediately dropping a bomb in the player's starting area. They must back into the far end of the hall they start in to avoid an explosion. As soon as the bomb blows up, Rhea will pop in and say "Seriously?!" in response to the bombs already causing trouble. The floor layout is a maze; To handle the floor, the player should separate all of the Pikmin in the corner. The falling bombs will all have trigger weights to drop ranging from zero to twelve Pikmin in weight. If the player has sprays to spare, they should walk Spicy Spray two Purple Pikmin and start running around, heavy enough to set all bombs off. If the player does not have the sprays, take 12 White Pikmin and do the same. Start moving left like a regular maze until you find the Shake-a-Smile. Then find the optimal path back to the starting area and set off all of the bombs on the path with your Pikmin crew. Then, return to the Shake-a-Smile, carry it back to base for 180 Pokos, and enter the second floor.

The floor layout has three sections separated by two floating platforms, each connecting one section to the one next to it. Upon landing, the player starts on the leftmost section, and a cutscene begins where the screen pans to the absurd amount of enemies on the rightmost platform. Rhea will finally have a breakdown and recommend the player refuse to engage, or at least look for an easier solution than the bloodbath that would be required if fought normally. Upon taking the first floating platform to the middle, 20 Orange Pikmin will be planted in the ground. Pick one up and a cutscene begins showing the Orange Pikmin. Rhea comments on how beautiful the creature is and maybe that the cave is not so bad. Immediately, a bomb drops. The player runs, the Pikmin stands there, and the bomb goes off. Rhea cries over how the innocent Pikmin was destroyed while smoke covers the screen. Eventually, the smoke fades to a molten shell and the Orange Pikmin coming out of the it. Rhea is happy that it is alive and concludes Orange Pikmin have to be immune to bombs.

The strategy to take out the rightmost platform is to ignore the rest of the Pikmin and cross on your own. The main issue will be the Bulbear and Dwarf Bulbears. Use any of the constantly fired explosives to knock out the Bulbear family. Return to the central platform, get all of the Orange Pikmin, and head to the right side. Now that the Bulbear family is dead, just grab the Time Marker wherever it was placed and take it back to the central base. None of the remaining enemies can hurt your Orange Pikmin, because they only have exploding attacks. Find the exit hole and wait for the cutscene where the treasure is brought back to the starting area for 180 Pokos and hop to the next sublevel.

The room is set up as a giant garden. Upon landing, start looking for Breadbugs. Walk slowly, because even though all you see are flowers, not everything here is a flower! Be on the lookout for Creeping Chrysanthemums or Shearwigs coming out of the ground. Kill them as soon as you see them, and wait for a Breadbug to come. Play tug-of-war with it and bring the beast back to base to kill the Breadbug. If the Breadbug had the S.S. Peppermint, go to its nest and take it after the Breadbug dies. If not, rinse and repeat until you kill the right one. Take the treasure back to base while following it with your crew to make sure no nasty surprises show up. After gaining 40 Pokos from the treasure, hop to the next floor!

The room is set up as a maze. Upon landing, quickly get into a dead-end section with no enemies and group the Pikmin there. Separate Your Orange Pikmin from the rest, and start getting to work. Isolate the Blowhogs and kill them, while making sure that you don't get a water puddle behind you and a Blowhog in front of you. Except for making sure the player is not blown up, any Dirigibugs and Volatile Dweevils can be ignored.
