Have you ever played a game of Hanafuda (Flower Cards)? A set of Flower Cards contains 48 cards depicting the beauty of the different seasons through nature. This March, you will be able to meet 7 all-new types of Flower Card 2024 Decor Pikmin, featuring two different cards each – that makes for a total of 14 new Decor Pikmin to join your squad!

Sorry about the earlier speculation.

This is the link to the event that starts 3/1. It looks like red, blue & yellow pikmin will be earned by collecting poetry slips, while the others will be from spins after mushrooms and such.

More details in the link. Mii clothes as reward for poetry slip milestones, like usual.
