π When it runs
October 1, 2026, 0:00 to October 31, 2026, 23:59 local time. New Halloween: Stained Glass Decor Pikmin debut, Halloween Light and Halloween Treat return for a limited time, and your Walk View gets a spooky makeover. The rest of October is in our October 2026 roundup.
πͺ Event Challenge: Stained Glass seedlings
- Each mission you clear gives a random reward: Stained Glass Cookies, Stained Glass seedlings, petals or other items.
- When the Big Flower at the center of the stage blooms, you're guaranteed a Gold Seedling on top.
- Seedlings grow into any of the 8 types at random, so a full set isn't guaranteed.
- Missions mix walking, growing Pikmin, Expeditions, planting Thistles and Marigolds, and clearing mushrooms.
πͺ Stained Glass Cookie missions
You get two sets of cookie missions: one awards event-limited Mii costumes, the other lets you pick rewards.
- Every 600 cookies lets you choose one reward, including Halloween Light and Halloween Treat seedlings. After a certain number of missions, only those two seedlings remain.
- Cookies come from Event Challenge rewards, planting flowers, Halloween Mushroom Mystery Boxes, and paid items (Premium Event Pass, bundle packs).
- Cookie missions disappear when the event ends and cookies have no other use, so spend them.
π» Halloween Mushrooms
Halloween Mushrooms drop Mystery Boxes with cookies and other items. The three Halloween decor types are strongest against them, and slightly stronger than usual against all mushrooms during the event.
Giant Halloween Mushrooms (rare Mystery Box) can appear on these dates, when you can also use the Mushroom Battle Bullhorn up to 3 times a day:
- October 3β4, 10β11, 17β18 and 24β25
- October 28β31
Join after the event has ended in your time zone and you won't get a Mystery Box.
π« Premium Event Pass (Lv20 and up)
- Extra seasonal Nectar for every stage cleared.
- At stage 4 and every multiple of 4 (8, 12, 16β¦), an extra Stained Glass Gold Seedling in a color you pick: red, yellow, blue, purple, white, pink, gray or ice blue.
- Rewards apply retroactively to missions already cleared.
- Early bird bonus: buy by October 7, 23:59 local time for 500 bonus Stained Glass Cookies.
