Pikmin Pluckin'
If you want to help Captian Olimar escape with his life, you'll have to generate a huge crew of Pikmin comrades. You can control up to 100 pikmin at a time and store an infinite number in plush spaceships called "onions".

A: The planet is crawling with natural Pikmin predetors. Command your fearless Pikmin to attack, then gleefully carry the defeated enemy body to the onion to generate more Pikmin.

B: Haul multicolored pellets to the onion for seeds.
Here is a table:

RED ONION TO... YELLOW/BLUE ONION
Pikminx2 Pellet (1) Y/B Pikmin x2
Pikminx5 Pellet (5) Y/B Pikmin x3
Pikminx10 Pellet (10) Y/B Pikmin x6
Pikminx20 Pellet (20) Y/B Pikmin x10

C: Once you get the hang of it, producing pikmin is a breeze! Deliver fallen foes and pellets to the onion to make seeds, then pluck more Pikmin Pals from the ground. Go, Pikmin, go!
