Firefly
Increases the size of newly planted crops.

Firefly matters when a crop is newly planted. Its reported size effect gives you a reason to think about the planting moment instead of equipping it only after a garden is already fully established.
How to get Firefly
Buy a wild Firefly in Garden Valley. Common Egg references exist, with hatch odds requiring a separate table.
- Acquisition status
- Reported available
- Availability
- Reported as a Garden Valley wild spawn. Current server stock and balance were not tested in game.
- Acquisition price
- 3,000,000 Sheckles reported for a Normal wild spawn.
- Acquisition odds
- 0.6% reported wild-spawn rate, not a confirmed hatch probability.
How the ability works
Its supported target is newly planted crops. The references describe a shared effect and a total size-bonus cap of 50%.
The baseline conflicts: one reference gives +1% per equipped Firefly, while another gives +2%. That disagreement propagates through the variant table, so precise bonuses are withheld.

When is Firefly worth equipping?
Plan the seeds you intend to plant while evaluating the pet. Larger crop size and higher fruit value are related through other mechanics, but this description does not establish an instant enlargement of every mature fruit.
The baseline is reported as either +1% or +2%, and the shared effect has a reported total cap. That disagreement prevents an exact best-stack recommendation or a precise expected return on an upgrade.
- Equip before planting if you want to use its described trigger. Existing plants are not evidence of a planting-time improvement.
- Compare Phoenix only as a different mechanic: Phoenix rerolls a mature plant and can produce a smaller result.
Trading status
Current player-to-player transfer availability has not been independently verified for this pet. No trading value is used as an in-game purchase price.
