Star Merchant

The Star Merchant (lit. 星际商人) is an NPC vendor who sells various exclusive items for both in-game coin and real-world currency.

 They will spawn once the following conditions have been met: 
 *  There is an empty House. 
 *  All players in the game world total more than between them in their inventories. 

''' Note that only coins in the main inventory or coin slots are counted; savings stored in a portable storage item like the Piggy Bank do not count toward the requirement. If the Star Merchant is killed, they will only respawn if the above conditions are met again. This means all players need to have over in their combined inventories. '''

Items sold
'''Unlike most other merchants, the Star Merchant's stock was not fixed and was instead determined by the game's remote servers. The following items are known to have been sold by the Star Merchant:'''
