Mystery Merchant Guide for Pet Simulator X

March 8, 2023

The Mystery Merchant is a NPC shop that appears at random intervals in the Cave biome of the Spawn world. It stays for 10 minutes at a time before departing, and sells 3 pets of different power levels. Each pet has its own quantity which is synced server-wide, so the stock may be sold out by the time you arrive.

It is often confused with the Traveling Merchant, which is a similar NPC shop, however the Traveling Merchant is more expensive, appears much more frequently, and spawns in the Shop biome of the Spawn world, and in the Trading Plaza.

Mystery Merchant Location

The Mystery Merchant has only one spawn location, and that is in the Cave biome of the spawn world. It only appears twice a day, and when it does, a broadcast is sent to the server stating that the "Mystery Merchant has arrived".

How to Purchase Pets from the Mystery Merchant

Similar to the Traveling Merchant, you can purchase pets from the Mystery Merchant using Gems. There are 3 "Respect" levels for the Traveling Merchant, and you can level up by purchasing more pets.

In-game UI for the Mystery Merchant shop

Each level of Respect that you reach, unlocks a new pet that you can purchase, from left to right. The pets are randomly decided each time the shop appears, and the pets sold are updated with every game expansion update.
