⚡ What Lightning Bug does
Every 9 minutes 5 seconds at base weight, there's a 10.25% chance a nearby fruit becomes Shocked, a ×100 mutation. It doesn't need Static first, unlike the Kirin's route to Shocked.
The wiki's history of this pet is unusual. It was once only obtainable with commands, was rumoured to be cut from the game, briefly vanished from the Garden Guide, and was then added back when the Season Pass made it obtainable.
📈 Firefly stats by weight
| Pet weight | Cooldown | Shocked chance |
|---|---|---|
| 10 kg | 8:15 | 11.25% |
| 25 kg | 7:00 | 12.75% |
| 50 kg | 4:55 | 15.25% |
| 100 kg | 1:50 | 20% |
The chance doubles to its 20% cap at about 98 kg. The cooldown falls 5 seconds per kilogram to a 1 minute 50 second floor at 87 kg, so a heavy Firefly rolls five times as often as a fresh one.
