The themed mushroom of each month's Decor Pikmin event, such as October's Halloween Mushroom. Every Pikmin can damage it and no type gets a matchup bonus. What decides the battle is event decor: each Pikmin wearing the event's new decor adds +300, and each wearing returning decor adds +100.
Event Mushrooms award stars from a separate score table that changes from event to event, so there are no star thresholds here. The calculators still give you the time to beat it, from the same formula as every other mushroom.
