Mutation reference
Twenty-one mutations are in the game. Most are linked to weather events; Cosmic (8×), Bubblegum (9×), Fire (10×), and Eclipse (12×) are spray-only. Effective per-plant rate is the product of event chance and per-roll chance.
Triggered by Eclipse Spray
The highest multiplier in the game at 12x. Eclipse Spray sits at the top of the Gear Shop at $50Qn, well beyond Fire Spray, making it a pure endgame purchase.
Triggered by Fire Spray
Update 4 spray-only mutation. Applied with Fire Spray from the Gear Shop at $1qd — the highest multiplier you can buy until Eclipse.
Triggered by Wizard Pass
Update 9 spray-only mutation that ties Fire at 10x. The Arcane Spray comes from the Wizard Event Pass rather than the Gear Shop; the Wizard Toad pet also applies it at 5% every 360 seconds.
Triggered by Carnival Spray
Update 5 (Carnival) spray-only mutation. Applied with the Carnival Spray — a Rare single-use drop from Spray Crates (~0.5%) earned via Carnival Pass Tier 11 or Carnival Crate spins, not sold in the Gear Shop. Reported at 9–9.5x across sources (Pro Game Guides 9.5x; Sportskeeda/SportsRant 9x).
Triggered by Bubblegum Spray
Update 4 spray-only mutation. Applies a 9x multiplier via Bubblegum Spray from the Gear Shop.
Triggered by Cosmic Spray
Elite 8x multiplier. Added in Update 3. Spray-only — no weather event triggers it. Also obtainable from Composter or Plant Rush shop (25,000 tokens).
Triggered by Bald Eagle
Update 9 Fourth of July mutation. Applied by the Liberty Spray from Uncle Sam quests 2 and 4, or by the Bald Eagle pet at 2.5% every 600 seconds. The spray was limited to the event week, but the pet keeps producing Liberty afterwards.
Triggered by Bee Swarm
Second-highest multiplier. Event-only from the Queen Bee event (0.5% per plant roll).
Triggered by Wizard Event
Update 9 event mutation. Rains down on your farm at random while a Magic Crystal blessing is active during the Wizard Event. Per-plant roll chance is not published.
Triggered by Meteor Shower
Event-only mutation from Meteor Shower weather. Per-plant roll chance is not published; the wiki lists it as unknown rather than zero.
Triggered by Galaxy
Premium 5x multiplier. Galaxy events are rare (4%) so most players buy the spray at $1T.
Triggered by Admin Abuse
Limited event mutation available during Build A Ring Farm admin-abuse sessions, which run weekly from the Saturday update. Cannot be upgraded by pets.
Triggered by Mega Farm
Event-only 4x mutation from the Trucker/Mega Farm event. Cannot be bought in the Gear Shop — apply it instantly with a Trucker Spray, an exclusive A/S/S+ grade reward from the Trucker NPC.
Triggered by Starfall Griffin
Pet-applied mutation from the limited Divine Starfall Griffin. Unlike standard mutations, Starfall stacks on top of an existing one — additively, so Fire plus Starfall is 14x rather than 40x.
Triggered by UFO
Event-only mutation. Cannot be purchased. Triggers during Alien Invasion events.
Triggered by Nuclear
Triples crop value. Best target after Void for mid-to-late game scaling.
Triggered by Plant Rush Golem
Pet-applied mutation from the Plant Rush Golem. Like Starfall, it stacks additively on top of an existing mutation instead of replacing it, so a Fire plant that picks up Vine sells at 13x.
Triggered by Black Hole
Major milestone mutation. The jump from Wet to Void is one of the best value upgrades in the game.
Triggered by Harvest
Doubles harvest value. Triggers during Autumn weather events.
Triggered by Blizzard
Mid-tier boost from Blizzard events. Pairs well with mid-rarity Epic crops.
Triggered by Rain
Entry-level boost. Cheap, frequent, and the most practical first mutation for early-game farms.

Alien Invasion | 2.5% | 2.5% | alien | 3.25× |
Trucker | 1.5% | 1.5% | farm | 4× |
Plant Rush | 0% | 0% | 0× | |
Queen Bee | 0% | 0.5% | honeycomb | 6.5× |
Mutation guide
The best mutation depends on how controllable it is, what it costs, and whether the target seed is valuable enough to repay the spray or event time.
Honeycomb is the strongest event-only mutation, but it depends on Bee Swarm. Keep plots full while online instead of planning your entire build around a rare event.
Rainbow remains the first practical endgame spray because it is available in the Gear Shop and multiplies Outer Ring seeds by 95x before other bonuses.
Fire, Bubblegum, and Cosmic sit above Rainbow by multiplier, but their cash cost only makes sense on your highest unit-price seeds.
Void and Radioactive are the bridge from Wet to endgame. Use them on Middle Ring value seeds before tying up cash in premium sprays.
Rainbow (5x) comes from Galaxy weather events (~4% chance per cycle, 1% per-plant roll). Effective rate: 0.04% per plant. You can skip the wait by buying Rainbow Spray from the Gear Shop for $1T cash or 279 Robux.
Honeycomb (6.5x) only comes from Bee Swarm events (~0.5% per cycle, 1.5% per plant). There is no Honeycomb Spray in the shop. Stay online with all plots planted to catch Bee Swarm when it fires.
Eclipse (12x) is the highest multiplier, followed by Fire and Arcane tied at 10x, then Carnival (9.5x) and Bubblegum (9x). Rainbow (5x) is still the practical first endgame spray because it costs $1T.
Yes. Acid Spray ($1M cash / 19 Robux) removes the current mutation. Only use it when you can afford the replacement spray.
Usually not — each plant holds one mutation and a new one overwrites the old. The exception is the two pet-applied mutations: Starfall (4x) from the Starfall Griffin and Vine (3x) from the Plant Rush Golem, which land on top of an existing mutation. That stacking is additive, not multiplicative, so Fire plus Starfall sells at 14x rather than 40x. Mutation multipliers do multiply with the ring and cash multipliers (Outer Ring 19x × Rainbow 5x = 95x).
Three usual causes. 1) Slot rules: each plant holds one mutation — new sprays overwrite the old one, and a cheaper spray won't replace a stronger mutation without Acid Spray ($1M) first. 2) Odds: event mutations roll at only 0.5–8% per plant, so most of your farm staying unmutated each event is expected. 3) Pet passives: Hydra and Mammoth upgrades cycle every 10 minutes and are chance-based. If an ability truly stops responding after an update, rejoin the server to re-register it.
