Spooked - September (Undertale Parody) lyrics

I can't remember What happened in September When everybody's gone When it's dark and i'm alone It's been forever Since I could have remembered Where the hell is everybody? I just wanna know the story Of what happened right before I became so alone... Still can't remember What happened in September Back when all the monsters died Trails of dust during my stride I just discovered That the monsters were defeated By something really strong It seems very weird and wrong It just doesn't belong Can't be from the underground Finally Finally it's done It's finally done Stop it you're going to k** them all Stop it! NO! No, i'm gonna save you I'm gonna save you all! Don't you try to stop me I've regained a small memory Came to my head just like that suddenly I think I've gotten a clue Something tells me this is worse than what I knew This is your redemption day everybody Go away from me! Stay away from me! Go away! You can't outrun me now! You see this knife here? I'm gonna use it! I just remembered What happened in September I'M THE REASON THAT THEY DIED I'M THE CAUSE OF GENOCIDE
