Traveling Merchant

The Traveling Merchant is a unique NPC vendor who randomly visits the player's Town for a day. His inventory is randomized and different every visit, selling 4 to 11 of the items listed below.

The Traveling Merchant can only spawn once you have at least 2 other Town NPCs, and only on days when no Events (with the exception of rain) are occurring. He does not require his own house in order to spawn, and will instead spawn near an existing NPCs, spending the day walking around near them.

Once the criteria are met, the Traveling Merchant has a 22% chance (roughly 1 in 5) of spawning each day, appearing at a random time between 4:30 AM and 12 PM. He generally stays for only one day at a time, after which he leaves at 6:00 PM. He despawns if the world is vacated before that time.

Items sold
(Note that these chances are per each slot, so the actual chances are multiplied by 4 to 11)

Trivia

 * Many of the things he sells are of Asian origin, many from the Qin Dynasty.
 * The name Willy is most likely a reference to the play, "The Death of a Salesman", by Arthur Miller, where the main character is named Willy Loman and is a travelling salesman.

Quotes
