Tremendous Sniffer: If you charge a Winged Pikmin or throw a Yellow Pikmin onto the fruit, the next day, it will be outside the wall.
Stellar Extrusion: In the Tropical Wilds, you are supposed to use 2 leaders to raise a seesaw block and get close enough to throw Pikmin at the Estellar Extrussion. But, by locking on to the fruit from a distance and charging Winged Pikmin, they may collect it, bypassing the seesaw challenge.
Astringent Clump: In the Garden of Hope, you are supposed to use all 3 leaders to raise and lower a weighted elevator platform and get close enough to throw Pikmin at the Astringent Clump. But, by locking on to the fruit from a distance and charging Winged Pikmin, they may collect it, bypassing the challenge.
