Autumn comes from a fan creator's original Sprunki character, rather than from an official Incredibox character, and was shared as a standalone sound for other fans to use. The creator pointed listeners to their GameJolt profile for more original character reveals, a common way Sprunki fans showcase new designs and sounds. Sprunki itself grew as a community-made music game inspired by Incredibox, where players mix character sounds into beats. Because Autumn is tied to a specific fan character, it is mainly used in character showcases, fan mixes and short videos that keep the normal-mode Sprunki style.
