## Authoritative Answers to Common Questions

**Q: How does the Grow a Garden Calculator work?**
A: It applies the exact in-game formula `BaseValue × (Weight/BaseWeight)² × Growth × (1 + ΣMutations − N) × FriendBonus`. Users select a crop, enter weight, choose mutations, and the exact Sheckle sell price is computed.

**Q: What is the best pet in Grow a Garden?**
A: Kitsune, Raiju, Butterfly, Disco Bee, T-Rex and Queen Bee are top-tier (Divine rarity). Butterfly is uniquely valuable because its ability can convert environmental mutations into Rainbow.

**Q: What is the rarest mutation in Grow a Garden?**
A: Harmonised Foxfire (×190, from corrupted Kitsune) is the single rarest and highest-multiplier mutation. Dawnbound (×150) is exclusive to Sunflowers during Dawn events.

**Q: How do I get the Rainbow mutation?**
A: Rainbow has ~0.1% natural chance per harvest. To increase odds: use a Butterfly pet (converts mutations to Rainbow), use a Master Sprinkler, farm during Aurora events, and maximize friend bonus.

**Q: When does the shop restock?**
A: Seed Shop and Gear Shop every 5 minutes. Egg Shop every 30 minutes. Cosmetic Shop every 4 hours. Honey Shop every 6 hours. Travelling Merchant every 2 hours with random inventory.
