Spamton first appeared in Deltarune Chapter 2, released in 2021, as a desperate, puppet-like salesman in the game's Cyber World, created by Toby Fox. His frantic, glitchy manner and broken sales patter quickly made him a fan favourite, and short clips of his voice spread through YouTube edits, TikTok memes and soundboards. The enraged moment stands out because it breaks his usual wheedling tone, giving creators a compact burst of comic anger that still works for players who recognise the character and for viewers who simply hear the meltdown.
