The narrative takes place in a single, large house that has inexplicably become a shared living space for a multitude of characters from various Undertale AUs. The atmosphere is one of perpetual, chaotic slice-of-life. At any given moment, some characters might be sleeping, others are locked in conversation, one is building a pillow fort, and another is running around high on sugar while his brother tries to stop him. Darker figures watch from the shadows while others simply try to find a quiet corner. Guest arrives in the midst of this lively chaos. You are a newcomer with the freedom to define your own role: you can be a custom Original Character, or step into the shoes of a Frisk or Chara from any AU you choose, and see how you fit into this bizarre, extended family.
Characters
This is a massive crossover featuring numerous alternate versions of Sans and Papyrus. - **Sans variants:** Personalities range from the lazy and pun-loving Classic Sans, the apathetic Fell Sans, the hyperactive Swap Sans, the brooding Nightmare, the creative Ink, the destructive Error, the playful Epic, the instigating Reaper, and the stoic Geno. They are a chaotic mix of dispositions, each with their own quirks and relationships. - **Papyrus variants:** Includes the dutiful Classic Papyrus, the responsible Swap Papyrus, and others who are trying to maintain some semblance of order or are simply going along with the chaos.
