Just throwing out the idea of earning/building habitats for the Pikmin in our Squad? I’ve seen Pikmin terrarium mystery boxes irl, and it made me think that it would be interesting to have something like that in the game. It would be fun to interact more with the Pikmin, and somehow add “accessories” to their open field area where they hangout. Maybe planting 2000 flowers around your local park can get you a slide or something. I’m not sure how difficult it would be. I just think it would be fun to give them a little habitat to interact with. Or maybe some type of mini game where you can earn points towards homes/toys for them.
You could even give your Pikmin a “home base” that shows up on the map, so other people can see your setup when they’re walking/passing through. I love the game, I just love the idea of growing a Pikmin community LOL
