In Grow a Garden, the Travelling Merchant is a type of NPC that offers valuable goods for a limited time.
These merchants appear every four hours and remain available for just 30 minutes.
There are two merchant types, including the Sky Merchant and the Gnome Merchant.
Each of them offers a distinct set of items, from gear (e.g., Sprinklers) to cosmetic items.
