All Rescues, Treasures, and Sublevel Caves: Day 17

Below is a quick summary of all the treasures and rescues you'll be able to find on this day. You can find the step-by-step Walkthrough on how to do this further down the page.

Back at Hero's Hideaway

The first thing you're going to do when you get back to Hero's Hideaway is to go back over to the box you moved earlier that revealed the small tunnel. Go through the tunnel and you'll be able to ride a rail which will take you to the island counter in the middle of the kitchen.

As you land, you'll see a number of things on the counter including a Porquillion, a few treasures, and a Flarlic. Hop onto the yellow button first, then focus on fighting the Porquillion. After this, you'll be free to collect the treasures and the Flarlic.

S.S. Peppermint

S.S. Chocolate

Surface Flarlic - Hero's Hideaway

Drop down with the Pikmin and call out some more once the Flarlic has been delivered. Grab Oatchi and ride the fan back up to the island. Before you go anywhere else, look down on the right to see a stool with another treasure on it.

Think-Tank Combobot

Now you want to go to the other end of the island, where you got the Flarlic. Press the button to turn the fan on, then Disband the group and have Oatchi stay here. Jump over to the table to pick up the next treasure.

Mechanical Harp (Windmills)

Now have Oatchi switch the air flow again and fly over to the shelves. You'll be met by a Leafling outside a Dandori Cave. Hop in and complete the Dandori Challenge.

Hefty Haulway (Dandori Challenge)

When you come outside, unravel the climbing rope and pick up the next playing card needed to open the vault. Get the second climbing rope unraveled and go back over to the tunnel that first brought you down to this area.

Courage Emblem

You'll want to go back up to the sink, and where you smashed the pots earlier, but this time go left and up the paper ramp. Smash the pots to get the Doggy Bed.

Doggy Bed

Drop down to the sink and press the White Button to drain the water. This will let you get the two tomatoes from the basin.

Love Nugget x 2

Continue to the left and towards the flames. In the middle of it is a sublevel cave. You can just jump into this quickly without it causing harm to your Pikmin.

Frozen Inferno

In this sublevel cave, you'll learn how to use Firestarters. With Red Pikmin, you'll throw them onto a fire and they'll come out carrying a Firestarter. You want to use these to light other coals around the area, and to burn down bundles of straw.

Follow the path around to the first section on the left, take out the Pyroclasmic Slooches, and grab the Cushion Cake treasure.

Cushion Cake

Go right and get the Flying Joustmite, then you'll come to another floor covered in lava, with a Fiery Bulblax guarding the fire. Focus on taking out the Fiery Bulblax first, then throw a Pikmin at the fire. Use this to burn down the straw on the left and pick up the Deceptive Snack.

Deceptive Snack

Use this Firestarter to light the fire near to the S.S. Beagle and destroy the bunches of straw to make a shortcut. While here, pick up the pile of Raw Material.

Turn left and throw the Firestarter up to destroy the bundle of straw on the higher ledge. Then go through the iron gates to pick up the pretzel.

Puzzle Snack

Go back to the first room where you got the Cushion Cake and throw a Firestarter at the bundles here to reveal two treasures. Then just head left, destroy the bundle and you'll be able to go down to sublevel 2.

Heroic Sword

Octoplus

Sublevel 2

The second level of the Frozen Inferno is a lot frostier than the first, and you'll learn here that this will slow down the Pikmin enormously. Just like in the previous level, there are bundles to be burnt down and fires to be lit, so that should be the main focus, but there are also ice blocks that need to be destroyed to dissipate the cold air.

Start by going to the left, break the first frozen block by having Oatchi rush toward it. Then go against the Chillyhop. When that's been beaten, you can go to the left and get some more Rock Pikmin from the Candypop Bud.

Go over to the pot where the ice block is and smash this, then go behind it. Stop by the grass first to get a Treasure, then go to the light blue Candypop Bud to get some Ice Pikmin.

Crush Nugget

Go to the right and build the ramp up to the next area, where Dwarf Frosty Bulborbs and a Frosty Bulborb await you. Get rid of the Dwarf Frosty Bulborb but leave the big one sleeping.

Then, push the Paper Bag down on the right and smash the frozen ice hiding in the grass here, which will help clear the cold air. Go down the Paper Bag, into the room on the right. The first thing you'll see is the Firestarter, so throw a Red Pikmin in and use this to light the fires in the room.

You can also use this on the Frosty Bulborb to remove its icy armor and make it weaker to attacks. When that's done, get your Rock Pikmin to break down the wall on the left and get the Treasure.

Insect Condo

Then return to the room on the right to fight the Icy Blowhog, which will drop a Treasure.

Stellar Extrusion

Get more Rock Pikmin from the Candypop Bud and pick up the pile of Raw Material, then it's time to go down to sublevel 3. Have your Ice Pikmin break down the wall to gain access to the next level.

Sublevel 3

You'll land right by a Treasure that you can't get at the moment, as you'll need to find a Firestarter. If you go left, you'll also see that the water is frozen so you can't hit the White Button to lower the walls.

For that reason, it's best to go right first. Hit the Icy Blowhog, then go into the next room, freeze, and break the Hydro Jelly so it's ready for lighting. From here, go left, and into the room with the Candypop Bud, Hydro Jelly, and Freezcake. Clear the room of any enemies, get Ice Pikmin from the Candypop Bud, and smash the Hydro Jelly to break the block of ice inside it. As the Freezecake dies, it will drop a Zest Bomb.

Zest Bomb

Then go left, and watch out for the Arctic Cannon Larva that will pop up from the ground. Use your Pikmin to carry the Seed Hive on the left back to the S.S. Beagle, then pick up your Firestarter on the right and set about lighting the fires in the room and burning down the bundles.

Seed Hive

Go back to the very start, to reach the first Treasure you saw. You'll also be able to shatter the ice block that sits near it.

Citrus Lump

Go to the previously inaccessible room, with another Arctic Cannon Larva and block of ice in the corner, and break the ice down. This will be the last one you need to clear the room of cold air. You'll now be able to press the White Button that was in frozen water to open the gates into the final sublevel.

Sublevel 4

In the final sublevel of this cave, you'll battle against a Snowfake Fluttertail. The key to this fight is using your Firestarter, so make sure you light one and go straight for the fires on either side. Get those lit, then wait for the Snowfake Fluttertail to descend.

It's coated in protective frost and will use ice attacks, so keep your Pikmin safe until you've broken its cocoon. To do this, use a Firestarter, and throw it at the Snowfake Fluttertail. It will break the ice and turn the creature yellow, so you know it's safe to attack.

When this happens, launch your Pikmin at it. Just repeat this process, and it won't be long before it drops the final treasure for this level. It will, at times, blow air at the fires on either side and put them out. Be sure to keep these lit, to help you take it down quicker.

Shattering Lance

Back on the Surface

When you exit the cave, you'll be higher up on the counter. Press the button, then go to the edge of the counter and look down for the open drawer in the freezer. Here, you'll be able to pick up the Light Blue Onion that will allow you to bloom Ice Pikmin.

Light Blue Onion

Now there's just one left to do and that's go to the bunker and open the door! You'll have picked up all three of the playing cards at this point needed to unlock the door. Inside, you'll find the Leafling and Moss and one final cave for Hero's Hideaway, which is the Leafy Showdown.

Leafy Showdown

With the Leafling Olimar rescued, you'll have to return to the Rescue Command Post and go out on at least one more Night Expedition to get to the credits and see the first ending of the game!
