The Sandsverse is a surreal expansion of the popular Undertale AU (Alternate Universe) culture, often blending the character Sans with abstract, sandy, or cosmic themes. It represents a niche corner of internet humor where the boundaries of character identity and reality blur, resulting in a 'multiverse' of bizarre versions of the same skeleton. These memes often poke fun at the sheer volume of Undertale fan content or lean into 'weirdcore' aesthetics to evoke a sense of existential confusion. On social media, the Sandsverse is a go-to for users who want to create deep-fried or ironic content that parodies the intensity of online fandoms while celebrating the internet's love for skeletal puns.
