< Pikmin
The Impact Site is the first place you will go. It has very few monsters. Most of the area isn't available until you get yellow and blue pikmin.
Day 1
On Day 1, you will land here and have infinite time. Go up to the brown thing and it will turn into a Red Onion. Then it will spit out a pikmin. Pluck the Pikmin. Have him knock down the Pellet Posies and get Pellets. Make as many as you can. When you get 10, push the box that has a 10 on it. Notice it takes 5 pikmin to carry a pellet with a 5 on it. Take the pellets you see. Inside the box, you will see bomb rocks which you will use later. You also find the Main Engine part.
