Pikmin

Instead of swarming it with Pikmin, get about five Blue Pikmin. Get in front of it. If the yellowish ball is in line with the black one, throw a Pikmin on it. It should spring back into the black ball and do a lot of damage.

There are usually two ways of killing a normal creature (ones that appear regularly); either throwing all of your Pikmin on it or using the C-Stick to get them to swarm around it. For the jumping frogs, never throw Pikmin on them or they will all be flattened. When the frog lands, swarm around it. If you have enough Pikmin they will stop it from jumping. For the big snoozing poker-dot bugs, get at least fifty Pikmin, Sneak around to the back of it and keep throwing quickly. It should not have enough time to turn around and gobble any Pikmin. For the square rock that keeps re-planting Pikmin, just get as much Pikmin as possible (seventy recommended) and throw for awhile before he gets too close. Then, run until he stops chasing and start throwing again.

You must be willing to sacrifice two or three Pikmin. Toss one at the pearl. When the clam closes and starts chewing, throw a group of Pikmin on top of it. When it opens, they will all fall in and start attacking it. Repeat as many times as needed. Note: When using leaves, you may need to sacrifice a few more.

Get a large group of Pikmin (preferably Red). Go up to the frog and dodge his first attack. Then, swarm him with your Pikmin. He will not be able to get off the ground, causing a near instant kill. This works with all frogs, but requires more with the Distant Spring frogs.

To defeat the frogs in the Forest Navel, get 20 to 35 Red Pikmin and press the C-stick to swarm the Pikmin around the frog. This should stop it from jumping and instantly kill the frog. To defeat the frogs in the Distant Spring, do the same thing, but with more Blue Pimkin.

You can kill the big killer frogs by getting 2 Yellow Pikmin and dismissing the Pikmin with bombs. Put them in front of the big frogs and walk in back of the frog. It will wake up. Quickly run away. It will go for the Pikmin, eat the bomb rocks, and die.

To defeat the Puffstool in the Forest Navel easily, beat him by yourself by pressing A near him. He does not do any damage -- just take the time to defeat him instead of losing a lot and Pikmin (and health since the Pikmin attack you).

Although it is true that Puffstool's spores do not damage you (because of your spacesuit), it is rather inefficient to damage him yourself. An army of red Pikmin are useful in battle, but you have to do two things. First, while Puff is standing, have them attack its feet. It will fall over on its head, wiggling around helplessly. Some will hang on to his feet, while the others will fall off. Instead of ordering them to attack again, throw your red Pikmin on top. His underside is easily damaged more than his head. However, it is very unlikely you will kill him before he flips over and tries to spray your Pikmin, turning them into Toadmin that will attack you. The easiest solution is to press B to recall them before he flips over, which is about fifteen seconds. Bring every one of them away from PuffStool and wait for it to spray. After the spores have dissipated, attack his feet and resume. It should only take two times to knock him out and get your part, as well as a mushroom cap to feed your Onions with.

To kill the Puffstool, have 20 Red Pikmin, 20 Yellow Pikmin, and 20 Blue Pikmin. Have all of your Pikmin attack him. When he falls, have all of your Pikmin away from the Puffstool. Attack the Puffstool with the punch that Olimar uses. Repeat this until it dies.

In the Forest Navel, you will have to kill a huge mushroom to obtain an item. Do not bring any Pikmin -- just Captain Olimar. Keep hitting the mushroom until it falls over. Continue attacking it until the he comes back up and sprays poisonous gases. This would normally turn your Pikmin evil and force them to attack their comrades. However, it does not affect Captain Olimar. Continue fighting the huge mushroom until it no longer moves. Then, bring in your Pikmin for the part and the body (for Pikmin).

Take out enough Pikmin (Red is best) to kill the frog by the Puffstool. Have 30 remaining to carry back The Omega Stabilizer. Once the frog is killed, leave the Pikmin out of he arena. Then, only as Olimar, attack the Puffstool. It should take about two Time Bubbles to finish off the Puffstool. This way, no Pikmin will be lost. Once you have defeated the Puffstool, carry it back to your ship.

Get 50 Red Pikmin and attack him. When he flips over, call them back and attack his legs. He should die before releasing the spores.

To defeat Smokey Progg (the swamp monster that terrorizes your Pikmin camp), simply throw Pikmin directly at his face. Be extremely careful as on Day 15 when he appears, his trail can kill Pikmin easily. When defeat him he will drop a dot which gives about 100 to 200 Pikmin. The best strategy is to get Pikmin out by tens (for example, 10, 20, 30, etc.)

Go to the Distant Spring on day 15 or earlier. Walk around until you find a small circle of islands with an egg in the middle. Throw one Pikmin on the egg, then retreat and wait for it to hatch. The Smoky Progg will appear. To defeat it, let it follow you back to your landing site. Then, take Pikmin out and throw them at its head. Note: If any Pikmin touch its tail, they will instantly die. The Smoky Progg has two methods of attack. The first is that it will uproot the Pikmin in the ground and they will most likely hit its tail. In the second type, it will shake the Pikmin off its head and run over them with its tail. The battle costs a lot of Pikmin and is not recommended if you are a beginner. If you defeat the Smoky Progg, the pearl it drops is worth 100 Pikmin. Note: The Smoky Progg disappears after day 15.

To kill the Smokey Progg faster, attack it when it is still in egg form. The Smokey Progg goes to your landing site after you go near its egg. It scares your Pikmin out of the ground and kills them. No color of Pikmin can kill the Smokey Progg when it is out of its egg. Even if you throw Pikmin anywhere on it, they die. It will never leave, so you cannot get any lost ship parts to your ship. Take about 20 to 30 blue Pikmin with you and go in a straight line from your landing site. You will encounter a bunch of rocks shaped like a flower. In the middle of the rocks, you will see a pink egg. Run up to it and throw your Pikmin on to it. Do not stop, or the Smokey Progg will leave its egg. When the egg is gone, the Smokey Progg is gone for good, leaving you plenty of time to get some of your lost ship parts before sundown.

In both the Forest of Hope and the Distant Spring, there is a beetle that carries a part. To defeat them, get 20 to 30 Red Pikmin and wait until it sucks in air. During that time, fire a Pikmin near it and it should get stuck in the sucker. The outer shell should open, revealing the vulnerable part on its body. Use the C-stick to rush your Pikmim onto the body and they will attack it. Repeat this until it dies. If you need Pikmin, take the beetle back to the Onion.

To defeat the Armored Beetle faster than swarming him, throw a Pikmin into his sucker when he breathes in and throw the Pikmin on top of his soft weak spot. He hould lose one third or more of his life in one of these types of bouts.

To kill the Armored Beetle in The Forest of Hope level, break the wall next to the beetle with 100 Red Pikmin. When he inhales, throw one Pikmin evenly with his nose. This should block it up. Next, run behind him and throw as many Pikmin as you can. Repeat this until it is defeated.

Captain Olimar can blow up the rocks that the Armored Cannon Beetle fires at the Pikmin by using Olimar's punch (press A). This is not effective in the Distant Spring, but in the Forest Of Hope. You can throw the required amount of Pikmin at the part and cover them while blowing the rocks up with Olimar's punch so that none of the Pikmin are hit. This does not affect Olimar's health. Note: You have to time it correctly to avoid missing the rocks and damaging Olimar's health.

In the Forest Navel when you face the Spider to get the Guard Satellite, get about 45 to 60 Yellow Pikmin and launch them at the body in the middle. This will quickly kill it before noon, giving you time to take it back to the Dolphin with Red Pikmin.

On day 15, before you get any parts in the Distant Spring, take some Blue Pikmin into the water near the Onions. Eventually, you will find a round island surrounded by smaller, stick-shaped islands. This is on the lower area of your radar. The island in the center will have a large egg on it. Break the egg, and a monster that resembles a phantom frog will appear. This only works if you have not yet gotten any parts in the Distant Spring and are on day 15. You can defeat the monster with bomb rocks.

On day 15, go to the Distant Spring. Before then, do not get any parts in the Distant Spring Area. Take a group of blue Pikmin and use your radar to search around for something that looks like a compass. It should be in the water to the northeast of the Onions. At the center of the little design there will be an egg. Clear all the frogs around the "compass" and clear the Puffy Blowhog next to the Onions. Go back up to the egg. Your Pikmin will want to attack the egg, but do not let them. Throw about three Pikmin at the base of it. The egg will start to rumble, then it will explode, releasing a strange creature into the level. Follow it back to the Onions. Be careful not to get Olimar or any Pikmin underneath the creature, as the Pikmin will die and Olimar will be damaged one quarter health. The creature will stop there and start following, trying to kill you. While you are battling this creature, do not look at your total number of Pikmin in your group. Instead, look at the number of Pikmin in the field. Use Blue Pikmin to defeat the monster, so that nothing bad happens to the Pikmin that fall in the water. Once it is defeated, and after the spectacular show, there will be a small seed where the creature died. Use three to six Pikmin of the color of your choice and bring it back to the Onion. The Onion will then sprout 100 of your color of Pikmin.

When you have to build the bridge from both sides to get the part for your spaceship, you may lose a lot of Pikmin from the frog that is there. Leave your Pikmin in their "Onions" when you begin and go over to kill the frog. It will be easier and safer for your Pikmin to build their bridge.
