What is the Toxic Mutation?
The Toxic Mutation turns normal fruit into toxic fruits that sell for a huge payout — it multiplies the fruit’s base sale value by 15×. Visually, toxic fruits show green dripping particles to make them easy to spot. 🟢💧
How to Obtain the Toxic Mutation
The Toxic Mutation is applied by the Cockatrice pet. To get a Cockatrice you must hatch Enchanted Eggs, which are rewards from the Fountain during the Fairy Event.
- Enchanted Eggs appear as Fountain rewards during the Fairy Event. 🧚♀️
- Hatch Enchanted Eggs to try and get the Cockatrice pet — it’s a rare drop.
Fountain Tiers & Enchanted Egg Chances
Higher Fountain reward tiers give better chances for Enchanted Eggs:
- Tier 2 — ~7.7% chance
- Tier 3 — ~17.3% chance
- Tier 4 — ~22.7% chance
- Tier 5 — ~29.4% chance and grants 3 eggs
Cockatrice Behavior & Mutation Mechanics
Once deployed in your garden, the Cockatrice periodically targets nearby fruits:
- It "spits" at multiple fruits about every 9 minutes.
- Each spit targets about 7–8 fruits.
- Each targeted fruit becomes Toxic and gets the 15× multiplier. 💸
Best Strategy to Farm Toxic Mutations
- Play during the Fairy Event and do the Fairy quests.
- Complete Fountain tasks and submit Glimmering crops to earn Enchanted Eggs. ✨
- Aim for Tier 5 Fountain rewards to maximize egg drops.
- Hatch Enchanted Eggs until you get the Cockatrice pet.
- Deploy the Cockatrice and prepare crops near harvest before its spit cooldown ends.
- Harvest and sell Toxic fruits for massive payouts. 🧾➡️💰
