☠️ Getting Toxic
Toxic comes from Venom Spit, the Cockatrice's second ability. Every 10 minutes 25 seconds at base weight it spits at 5 different targets. Fruit that are hit get Toxic, eggs skip 80 seconds of hatch time, and pets gain 800 XP. Because the targets can be fruit, eggs or pets, not every spit has to land on a crop.
A heavier Cockatrice spits more often and at more targets. The cooldown falls 3.5 seconds per kilogram to a floor of 3 minutes, and the target count rises by 0.1 per kilogram up to 10:
| Cockatrice weight | Venom Spit cooldown | Targets |
|---|---|---|
| Base | 10:25 | 5 |
| 10 kg | 9:50 | 6 |
| 50 kg | 7:30 | 10 |
| 100 kg | 4:35 | 10 |
The Cockatrice is a Divine pet from the Enchanted Egg (1%), added in the first half of the Fairy Event 2025 on August 30, 2025, and the wiki lists it as no longer obtainable. Its page also notes that Venom Spit can't be copied by mimic pets.
🔗 Toxic + Acidic = Corrosive
Per the wiki, Toxic and Acidic on the same fruit fuse into Corrosive, a ×40 mutation. Acidic (×15) comes from the Acid Rain weather. Apart, the two would add 14 + 14 = 28 to the mutation total; Corrosive adds 39.
Corrosive is in turn one half of Contagion (×205), with Biohazard. So if you have Toxic fruit and Acid Rain is on the way, leaving them on the plant gives the fusion a chance.
