Name-entry item spawn (works on every platform) (Easter Egg)
Naming yourself or an animal with an item code in brackets, e.g. [163], makes the item drop whenever the name is spoken in dialogue. Purely single-player, works on Switch, PlayStation, Xbox, PC and mobile.
Name: [163]
Start a new farm (or rename via the cat/dog naming prompt) using bracket codes like [163] for a Legend fish worth 5,000g — each time an NPC says your name, the item drops.
