All missions 100%: just like it says complete all missions, however an issue is the repeatable missions. My proposal is that you have to finish those missions at least once.
Olimar low%: rescue olimar with the minimum treasures, onions, flarlics, upgrades, items, missions completed, and materials collected.
Oatchi low%: cure oatchi with the minimum treasures, onions, flarlics, upgrades, items, missions completed, and materials collected.
Daddy%: idea by Dazzreviews2 on YouTube, getting to and defeat the empress bulblax fast as possible.
Pikmin%: get at least one of every pikmin type: reds, yellows, blues, purples, whites, rock, winged, ice, and glow.
Onion%: get at least one of each onion type: red, yellow, blue, purple, white, rock, winged, and ice. Maybe put the purple and white onions in a subcategory.
