Defeating Beady Longlegs
This Boss is found in the Hole of Heroes and Citadel
of Spiders. To defeat it, throw Pikmin at its belly when it roars,
Defeating Burrowing Snagret
This Boss is found in the White Flower Garden, Snagret
Hole (x2), Hole of Heroes, and Dream Den. Defeat by throwing Pikmin
at its heat, and not the body. Call the Pikmin back if it flinches
Defeating Careening Dirigibugs
Careening Dirigibugs are the bugs that float around suspended from balloons and drop explosives on you and your Pikmin. If you sneak up behind them before they take out an explosive, then knock it out of the air by throwing a Pikmin at it. There will be no explosives on the ground to kill your Pikmin, so you do not have to call them away before the Dirigibug has been defeated. If it has already gotten out an explosive, wait for it to drop it, then immediately knock it out of the air by tossing a Pikmin at it. Use the C-stick to make the rest of your Pikmin swarm around it. While your Pikmin are attacking the Dirigubug, charge towards the bomb (use X to release any Pikmin not attacking first to keep them out of harm's way), and use Ato punch it away from your Pikmin.
Defeating Emperor Bulblax
Take about ten Purple Pikmin and use the Ultra-Spicy
Spray on them. Throw them all on the giant Bulblax. The Boss should
be defeated in just a few seconds.
You must be willing to sacrifice a few Yellow Pikmin for this
trick. In the Final Trial area, once you are ready and have cleared
a path leading to the Emperor Bulblax, get about 10 to 15 Yellow
Pikmin. Then, head up the path straight to the round-shaped arena.
Sneak past the Emperor Bulblax and you will see a hill leading
to the top of the arena. Go left and right, searching for as many
bomb-rocks as possible. Then, go back to the bottom of the arena
and wake up the Emperor Bulblax with Captain Olimar. Once he has
awakened, get directly in front of him. He will open his mouth
with his huge tongue and will slurp them up. After that, right
inside his stomach, a huge explosion will happen inside his body
and a huge chunk of his health will be wiped out. Repeat this
until you are out of Pikmin, and he will probably be dead by then.
Note: On your way up the hill in the arena, there will be a gate.
This Boss is found in the Cavern of Chaos, Bulblax Kingdom, Hole
of Heroes (x2), and Dream Den. Defeat it by throwing Pikmin at
its face. Do not attack it head on, as it will eat a lot of Pikmin.
Call the Pikmin back when it flinches. It may stomp on you. In
the Cavern of Chaos, make it lick bomb rocks by luring it by them.
In the Hole of Heroes, defeat the one that swallowed the treasure.
One will be guarding the hole to the next floor. Avoid it by making
the president take all the Pikmin, and put him in a safe location.
Then, use Olimar to go to the floor's hole, and you will be unharmed.
At the Cavern Of Chaos, dismiss your Pikmin when you see the Emperor
Bulblax. Wake Emperor Bulblax and put him near the bombs. He should
lick them then he should gobble them up. He will then lose a chunk
Use the following trick to defeat Emperor Bulblax in "Hole
Of Heroes" without losing Pikmin. In a sublevel in the Hole
Of Heroes with a lot of Emperor Bulblax and bombs laying everywhere,
place your Pikmin in a safe spot. Venture off to wake up all of
the Bulblax without touching the bombs. Stand next to a bomb or
two and let the Emperor eat them. This will take out a large amount
of his HP. Do with all Emperors and you will not lose any Pikmin.
Defeating Empress Bulblax
Take about three to five Red Pikmin and go into the
corner directly next to Empress Bulblax. Start to throw all the
Red Pikmin on it. When it is about to shake them off, whistle
your Pikmin back and go into the corner, pressing the C-stick
Down, so they will be behind you and therefore will not be
crushed. Keep repeating those steps until you defeat Empress Bulblax.
This is a good strategy to use to keep most of your Pikmin alive.
This Boss is found in the Frontier Cavern (with larva), Hole of
Beasts (without larva), Hole of Heroes (with larva), and Dream
Den(without larva). Defeat her by throwing Pikmin at her head.
Call your Pikmin back when she flinches.
Defeating Fiery and Watery Blowhogs
If you do not want to risk having your Pikmin drown
or be burnt to death, you can punch these Blowhogs to death as
just Olimar, Louie, or the President of Hocotate Freight. Stand
facing the Blowhog's eye, at about a 45 degree angle to its snout,
and repeatedly press A to punch it. Stand back a bit, and
not directly against it, and you will not be hit by its stream
of fire or water, or its lunging attack.
Defeating Giant Breadbug
This Boss is found in Glutton's Kitchen. Throw Purple
Pikmin at its back.
If there are treasures in the area of the Giant Breadbug, do not collect them. Instead, wait for the Breadbug to try to grab them, then use the C-stick to swarm your Pikmin around the treasure. Only do this if you have more than enough Pikmin to carry the treasure. They will drag the treasure along with the Breadbug back to the ship. The ship will beam up the treasure, dropping the Breadbug to the ground and doing quite a bit of damage to it. If the Breadbug is winning the tug-of-war for the treasure, whistle to call your Pikmin back to you, or they will be dragged into its hole and get killed. This will also work with corpses of other enemies as a substitute for treasure, and with the smallerBreadbugs.
Defeating Louie's spider Boss
Go head on to the Boss with only Yellow Pikmin.
This Boss is found in the Subterranean Complex, Hole
of Heroes, and Dream Den. Defeat it by throwing Pikmin at its
main body. Flee from the laser by hiding behind short walls in
Defeating Pilated Snagret
This Boss is found in the Snagret Hole, Dream Den,
and Hole of Heroes. Defeat it the same way as the Burrowing Snagret.
Defeating Puffy and Withering Blowhogs
Stand under the Blowhog, keeping your Pikmin under
it as well, and throw them at its belly. This will keep your Pikmin
safe from its breath so they will not be blown away or have their
flowers wilted. Use the C-stick to move your Pikmin under
it. Yellow Pikmin work best.
Defeating Raging Bloyster
This Boss is found in the Shower Room, Hole of Heroes,
and Dream Den. Defeat it by separating your Pikmin into two groups;
one with Louie (or president), and Olimar. The Bloyster will then
go after the pilot you are controlling. When the other pilot has
an easy target at the tail, throw Pikmin at it. Note: Yellows
do not work well.
Defeating Raging Longlegs
This Boss is found in the Hole of Heroes. Defeat the
spider by throwing Purple Pikmin at its huge belly. Then, call
the Pikmin back when it flinches.
Defeating Segmented Crawbster
This Boss is found in the Cavern of Chaos. Throw Pikmin
at its soft belly. Call them back when it starts to roll. Avoid
the falling rocks.
Either throw Pikmin on top of them, or make them drown
in nearby water and they will instantly die.
Defeating Sleeping Bulborbs
Take a few Purple Pikmin (about 10 to 20) and slowly
sneak up behind the sleeping Bulborb. Take into consideration
the fact that Orange Bulborbs wake up much easier than Hairy and
Red Bulborbs. Throw all of your Purple Pikmin onto it quickly,
which should stun it before it has time to attack. They will quickly
defeat it before you lose any Pikmin. Do not attempt this with
the Fiery Bulblax, as the Purple Pikmin will be burnt.
Defeating Spotty Bulbear
On sublevel 3 of the Dream Den , take one Pikmin to
lure the Spotty Bulbear down. Note: You need Pikmin to lure it
down. Run past a pit. The Spotty Bulbear will follow you. It will
climb over the wall and fall into the pit. The treasure that it
ate, the Glee Spinner, will appear beside the pit that it fell
Defeating Titan Dweevil (Master)
This Boss is found in the Dream Den. Split into groups.
Put the non-attacking group in a safe location, far away. First,
destroy its Hydro Cannon with Yellow Pikmin. The Water Cannon
can reach farther than any other weapon. Next, destroy the Plasmatic
weapon with more Yellow Pikmin; then the Flare Cannon with Red
Pikmin; and finally the Poison Exhauster. Once that is destroyed,
destroy the spider with any color Pikmin. It will not attack.
The Titan Dweevil is located on the Final Floor of the Dream Den.
Bring 25 each of Red, Yellow, Blue, and White Pikmin. You do not
need the Purple Pikmin, as you will just end up losing them. When
you first get there, you will see Louie sitting on a lump of "treasure".
Take your Yellow Pikmin down to where he is located. Leave the
rest of your Pikmin with the President. The Research Pod will
comment on the situation. As soon as he is done talking, the creature
will appear from the ground. Use your Yellow Pikmin to hit the
yellow "cannon" by its head. Because the electricity
will not harm the Yellow Pikmin, you do not have to frantically
call back your Pikmin. If the Boss uses its flamethrower (the
creature will turn red), take your Pikmin to the back of the battlefield.
When it uses its hydro-pump, switch to the President and continuously
use whistle on your Pikmin. This will prevent them from getting
damaged. Do not worry about Olimar and his Pikmin, as they will
move about by themselves to dodge the water. After the electric
cannon is destroyed, get your Pikmin back up to the President,
gather up your Blue Pikmin, and destroy the hydro-cannon. You
must wait until the creature roars and stoops low enough for them
to reach. When the cannon starts to smoke and it uses it, the
shots will fire rapidly. Switch to the President and call your
Pikmin with the whistle as done earlier. When you knock off the
water cannon, you never have to switch to the President again
(unless you want to get a different group of Pikmin). Gather up
your Red Pikmin and destroy the flame-thrower. Once that is gone,
the only weapon that remains is the poison thing. Take all your
White Pikmin this time. Once the poison cannon is knocked off,
the spider's metal skin will shed, revealing a softer Titan Dweevil.
All the Dweevil can do at this point is shake off the Pikmin that
you throw on it. Just call all your Pikmin and throw them all
like you would with Purple Pikmin on a Spotty Bulborb. It cannot
do anything about it. You will now see the pie graph-like life
bar. Once it dies, you need to take Louie back to the Research
Pod. He is worth 10 Pokos. The cannons are actually treasures
worth that are worth 1,000 Pokos each.
This Boss is found in Submerged Castle. If you encounter
the Boss in another sub-level than the final one, it is invincible
-- flee immediately. When at the final floor, throw Purple Pikmin
to hurt him. When he is off his rollers, you need to do the same
thing. Note: He will come on any floor he desires. To avoid this,
do not spent a lot of time there.
Defeating Bosses whose attack involves eating Pikmin
If you have a good number of White Pikmin when you
get to the Boss of the hole you are in (15+), take a few of them
into the arena with you, and nothing else. Get the Boss to eat
the Pikmin. It will lose a very large amount, if not all, of its
Defeating enemies quicker
Have an army of Purple Pikmin. Keep throwing them on
top of an enemy (place the pointer directly underneath the enemy).
In most cases, this will paralyze enemies and kill them in just
a few seconds. Note: This does not work on all enemies.
Carry items quicker
Use White Pikmin to carry items. They can do it much
faster than any other type of Pikmin. However, for items which
have a weight value of 100 or more, use a combination of White
and Purple Pikmin.
Escape Bumbling Snitchbugs
Bumbling Snitchbugs will swoop down and grab you, then
throw you down, doing some damage. When you are grabbed, your
Pikmin will be released from your control until you are freed
and whistle for them. If you are captured, quickly rotate the
Analog-stick to free yourself from the Snitchbug's grasp
and avoid any damage.
Protecting Pikmin from explosives
On Sublevels, when you notice there are a lot of explosives
about, drop your Pikmin off in a safe area with X. Then,
run through the level punching all the explosives on the ground
to set them off. Run into pipes and corners to upset Volatile
Dweevils so that they explode, and so any explosives set to fall
from the ceiling will do so and detonate without harming your
Non-Blue Pikmin and water
If you have non-Blue Pikmin in the water and you have
Blue Pikmin with you, toss the Blue Pikmin in the water with them
close by. They will go to the other Pikmin and toss them out of
the water themselves This saves time and pikmin.
These little creatures are parasitic Pikmin that infect
and control Bulborbs (see Olimar's Notes in the Piklopedia for
more details). They can be found underground (for example, at
Green Hole). You will see a Bulborb with a leaf coming out of
its back, just like the ones on your Pikmins' heads. Following
it around will be a few smaller versions of the parent. Note:
There will not be any if you have 100 Pikmin. There are only a
few available, and only enough to make up the difference to give
you 100 Pikmin/Bulbmin following you around. For example, if you
have a party of 97 Pikmin in an area with Bulbmin available, there
will be 3. However, if you only have a few Pikmin, there will
not be a large quantity to make up the difference and give you
a total of 100. When you defeat the parent Bulbmin, the little
ones will run around and obey you if you whistle for them. They
are immune to fire, water, poison, and electricity, can carry
things, and will fight for you. However, they will not come above
ground with you. They are only temporary allies that will remain
with you only when you are underground.
When you see a small Bulborb (for example, small red
Bulborbs, etc.), look at its entry in the Piklopedia. It will
mention that small Bulborbs are actually members of the Breadbug
family, and actually use camouflage to disguise themselves as
Ravenous Whiskerpilliar larvae
In the Wistful Wild, there are a group of what appears
to be Ravenous Whiskerpilliar larvae. They will drop sprays, nectar,
do nothing, or poison non-white Pikmin. They drop lots of sprays
They only appear on days 31 through 39, 61 through 69, and 91
through 99, etc. When you land in the Wistful Wild, get 20 Purple
and about 50 Blue Pikmin. First, kill the Dwarf Red Bulborbs,
then go left to the area where the Cavern of Chaos is located.
Do not go in it. Next, go up the ramp to the area where the three
eggs are found. Break them open if you need nectar. If you are
out of Ultra-Bitter Spray and an egg drops some, save it for later.
Go up to the next area and kill the small Bulborbs. Next, go into
the water and kill the Yellow Wollywog. Go up to dry land and
look around for the Gatling Groink. Lure it towards you, then
freeze it with Ultra-Bitter Spray. Toss your Pikmin on it as fast
as possible; if you defeat it while it is petrified, you will
not have to take it back to an Onion to stop it from regenerating.
Next, go back to the rolled up bridge and kill the Cloaking Burrow-Nit.
Do not worry about the Fiery Blowhog unless it is close to the
bridge, because you can just bring your Purple Pikmin across the
bridge to kill it fast. Go to the area with the three Creeping
Chrysanthemums and the two Withering Blowhogs. Kill them all.
Then, look for a small spot with little yellow dots swarming around.
The dots are the larvae. Purple Pikmin to kill them, but call
them back if they are poisoned.
When you defeat the Waterwraith, go to your Piklopidia.
Go to his entry and listen for awhile. You will hear it singing.
When in the submerged castle, dodge the Waterwraith until you
get to the final sub-level 5. You will have to get the Purple
Pikmin and take only them to the eggs to power them up. Then,
break down the door to the big circle area. Let him fall. Wait
until he moves then put Olimar in a safe area. Use the President
to fight. When it is moving, throw the Purple Pikmin on him and
he will freeze. Then, just keep throwing them. When he falls off
his wheels you will have to chase him and make him tired. Then,
throw the Pikmin again. Keep doing this to defeat him.
Swooping Snitchbug gets flower
When the Swooping Snitchbug picks up one of your flower
or blossom Pikmin, it will lose its flower.
Getting the desired color Pellets
The Pellets in some Pellet Posies will flash different
colors, and will often change from the color you want by the time
your Pikmin have destroyed the Posey. Instated of swarming your
Pikmin around the stem, stand in front of the Pellet Posey until
the Pellet changes to the color you want. Then, throw a Pikmin
at the Pellet itself. This will automatically destroy the Posey.
This trick works best with Yellow Pikmin.
Decorated Cannon Beetles as weapons
Decorated Cannon Beetles resemble fat caterpillars
and spit rocks at you and your Pikmin that will lock on to you
and chase you around. These rocks will automatically kill any
Pikmin they roll over. If there is a Decorated Cannon Beetle near
other enemies on the ground, press X to drop off your Pikmin
in a safe area, then stand in front of the Beetle to get it to
shoot a rock at you. When it does, run behind another enemy so
the rock will hit it trying to get to you. The rock will damage
or kill the other enemy and leave you unharmed. This trick can
be used to get Decorated Cannon Beetles to kill themselves as
well, but this is more difficult and requires more open space.
Wait for it to spit a rock at you, then run out and around in
a circle, stopping behind it.
Escape floors without worrying about losing Pikmin
When you land on a floor you have either already cleared,
one you know is very difficult, or just want to skip, separate
your characters and have one of your them (Olimar, Louie, President)
have control of all the Pikmin. Then, switch to the character
with no Pikmin and find the hole to escape with all your Pikmin.
If the hole is sealed, then you need your Pikmin. However if it
is open, then enter it and all your Pikmin will appear in the
plunging scene; the ones who were with your other character, even
though they were somewhere else. You must have all your Pikmin
called upon by the character who stayed behind or not all of your
Pikmin will make it to the next floor. If it states you do not
have all your Pikmin, just switch characters. Then find the stranded
Pikmin and switch back to escape. Check your numbers at the bottom
of the screen so you do not have to worry about it. This should
also work with spouts.
Turn enemies to stone
Open your Piklopedia and go to the entry for an enemy. While viewing the entry, press Z to turn it to stone.
Deflect enemy attacks
If the Armored Cannon Beetle larva or the Decorated
Cannon Beetle fires a rock, wait for it to break then try to aim
its target at a wall that the rock will bounce off. It will rebound
and hit itself. Also, if there is an enemy or the poison thing
or thunder thing near it, try to hit one of those with the rock
