How To Get the Koi Pet in Grow a Garden
To unlock the Koi, follow these steps:
Koi Pet Info
Fish of Fortune Explained
Koi’s passive, Fish of Fortune, gives you a 0.61% chance to get the egg back when you hatch it. This ability doesn’t work on Premium or Exotic eggs.
Even though the official banner said the pet boosts egg hatch luck, its real function is to refund the egg itself, which has disappointed some players. Still, if the ability procs, you’ll end up keeping both the pet and the egg, essentially duplicating it.
The passive can stack, so if you equip multiple Koi pets, your refund chance increases. For example, 8 Kois give you a combined ~4.88% refund chance per hatch.
This makes Koi incredibly useful for farming rare non-premium pets like Kitsune, especially if you’re trying to build duplicates.
Is Koi Worth Using?
Yes, but only if you’re hatching non-premium eggs regularly. While the refund chance is low, stacking Koi pets increases your odds, and the long-term benefit of egg recovery can pay off big.
Many players wish the chance were slightly higher (e.g., 1%), but it’s still one of the few passives that directly offsets your hatching costs.
