Sprunki began as a fan-made mod of Incredibox, the browser beatboxing game, and spread quickly through YouTube and TikTok gameplay videos in 2024. In its normal mode characters sing loops, but Black is linked to the hidden horror side of the mod, where the bright style turns dark and unsettling. Clips of that transformation, especially the jumpscare, were reposted as standalone memes and sound effects, so creators now use the audio even outside gameplay, whenever a video needs a sudden horror reveal or a joke scare.
