Update 30.1 is the 
Halloween Event 2026, released on October 31, 2026. The update brings 
Hellfire, the mutation of the Gas fruit, the return of 
Trick or Treating during the Harvest Moon, two new raid bosses (
Hellfire Gas and 
The Great Pumpkin) with the 
Unbound Werewolf's return, two potions, two accessories, two enemies, two materials and the 
Spooky Gacha. It also pulls 
Venom from sale. The event runs until November 15, 2026 at 1:00 AM UTC.
How to get it
Released on October 31, 2026 at 2:00 PM UTC under the name Halloween Event 2026, with the tagline "Hellfire Mutation + Trick or Treating!". A first batch of fixes is dated the same day (details below). The Fandom hesitated on the number: an "Update 31" page was created then blanked on November 1, and the 
Updates/30.1 page is the one rewritten during the day. Several of our pages for this edition say "Update 31": it is the same update.
Hellfire, the Gas mutation
The headline is Hellfire, the 
Mythical mutation of the Gas fruit and the first mutation of a non-Beast fruit. Three ways to get it: the physical fruit as grand prize of the Spooky Gacha, the Soulfire Bundle in the 
Shop (3,499 Robux, 2,800 with Roblox Plus for over two months), or 1,250 Robux in the Mutations section of Gas if you own permanent Gas. The Hellfire Gas raid boss can also drop the physical fruit, very rarely. Its moveset, cooldowns and transformed form are on the Mutations page.
Trick or Treating and the two raid bosses
Trick or Treating is back during the Harvest Moon, 10 minutes every hour: you knock on building doors for 
Candy Corn, and a door can open a portal to a raid boss. All three seas are decorated for Halloween.
- Hellfire Gas, new: Lv. 3000, 415,000 HP, hidden in
The Pit dimension behind a Harvest Moon door. It leaves 250 Candy Corn, a 
Candy Concoction, 1,000 to 1,100 Beli and, very rarely, the physical Hellfire fruit. - The Great Pumpkin, new: Lv. 3000, 415,000 HP, opened at the
Witch with 200 
Pumpkin Bits and 3 
Cursed Pumpkin Seeds. It leaves around 1,000 Beli, Candy Corn, the Pumpkin King Title, the Great Pumpkin profile background and sometimes the 
Great Pumpkin Top Hat. - The 2025 Unbound Werewolf is back behind the doors, 400 Candy Corn and a Candy Concoction.
The 
rip_return boss also returns in its Trick or Treating room, according to the notes.
Enemies, materials and currency
- Two new enemies: the
Jack-o-lantern, which comes out of a destroyed pumpkin, and the 
Pumpkin Snowman, three stacked Jack-o-lanterns. - Two new materials: Pumpkin Bits (pumpkins, Jack-o-lanterns, Pumpkin Snowmen, capped at 1,000) and the Cursed Pumpkin Seed (Pumpkin Snowman).
- Candy Corn returns as the Spooky Gacha currency, 500 per roll.
Spooky Gacha, accessories and profile backgrounds
The Spooky Gacha sets up at the 
Blox Fruit Gacha spots (
Middle Town, 
Café, 
Mansion): 500 Candy Corn per roll, two rolls per hour, cooldown shared with the regular gacha. Hellfire as grand prize, a physical fruit above 
Common, three potions, three profile backgrounds and three Mythical accessories.
 Accessory | Status |
|---|---|
 Mummy Headdress | New (12th Spooky Gacha roll) |
| Great Pumpkin Top Hat | New (possible drop from The Great Pumpkin) |
 Pumpkin Mask | Back from 2025 |
 Coven Witch Hat | Back from 2025 |
New profile backgrounds: Hallow Forest, Great Pumpkin and Tarot. Returning: 
Full Moon and 
Halloween Tapestry. The Tarot background is the only echo, on the Fandom side, of the Tarot card deck promised by The Blox Bulletin 025.
Potions
The Witch returns with two new throwable potions: the 
Poltergeist Potion (everything in the area floats) and the 
Soul Swap Potion (players in the area swap avatars). Seven 2025 potions return: 
Disguise Elixir, 
Suspicious Growth Potion, 
Big Head Elixir, 
Pumpkin Potion, 
Lava Bomb Elixir, 
Monster Mash Elixir and Candy Concoction. The Pumpkin Bits recipes are on the potion pages.

Blox Fruit Dealer, with no return date. - The Blox Fruit Gacha gets a new outfit for the event.
- You can now see whether a fruit is in stock at the Dealer even when you own its permanent version.
