so I just got a concept out of nowhere; So there's this innocent cartoony bunny named "Bunni" (yes) who is the generic happy optimist character you'd typically see on kid shows. She and her animal friends planned to go to this "great museum" in order to see "cool stuff". But due to issues and shit her other friends couldn't go. So she decides to just go alone instead. But while she was observing this particular statue, it just feels like everyone in the museum just disappeared. Suddenly, a stairway leading to an old and dusty basement appears. Her, being the happy go lucky naive little shit she is, decides to go further down and explore in order to see more "cool stuff". Unfortunately, when she gets down the stairs, they just straight up vanish. Even worse, the "basement" that she entered is ACTUALLY an old forgotten "base" for a cult who worships satanic eldritch gods. As she explores the place and goes deeper and deeper through, she starts to slowly lose her composure. (also it's like, pitch black and she can barely see her own hands in front of her face) after stumbling across this "alter" in a particular room, it suddenly goes pitch-black and she is eviscerated by some unknown force\creature. As she lays on the floor bleeding out pretty quickly (from literally not having half her limbs) she truly realizes how cruel life is and how not everything is as good as it seems.
