Seed Pilot Pikmin 4 The World to Free
Back story
Captain pikmin wanted to make a machine, that could help detect the perfect landing spot. He believe that if he made little add on ships to the main onion, they would lower the risk of searching, and to gather more info on the terrain.
In game
Seed pilots play a role for finding the first 3 pikmin in the game, which all happened to have a problem on their way to land and got trapped somewhere. Sadly only a seed pilot could escape out of. Seed pilots are only available for the reds, yellows, and blues and you only can carry a total of 50 pikmin for each color. They don't appear again with you after you rescued their onion, but when Alice decides to depart on her own. She gets to bring the seed pilots with her.
Seed pilots also are run only by wireless surges. So if they lose transmission towards the onion, they power down and heads back towards the onion. This means that the area you found the seed pilot is where you can only have it. However Captain Pikmin fixes this problem, so Alice could use them.
