Morshu first appeared as the shopkeeper in Link: The Faces of Evil, released for the Philips CD-i in 1993, and his rubies line later became a long-running YouTube Poop and remix staple. Spamton arrived decades later as the glitchy salesman in Deltarune Chapter 2 in 2021, quickly inspiring songs and edits around his big shot catchphrase. Spamshu brings the two merchants together as a fan mashup, treating their very different sales styles as if they belonged in the same shop and the same song.
