Click the green flag and listen to the epic song of Sans and Chara battling each other. Lyrics to the song are: Sans: It's a beautiful day outside, birds are singing, flowers are blooming. On days like these kids like you, SHOULD BE BURNING IN HELL! Sans: Turn around kid, it be a crime. If I had to go back on the promise that I made for you so don't step over that line, or else friend you're gonna have a BAD TIME. Chara: But guys like you are always just fools. Come at me, try to kill me with your fancy tools. Sans: Let's go, let the room get chiller. Let's go DIRTY BROTHER KILLER! Sans: Go ahead and try to hit me if you're able. Chara: But inside you know the end can't be evaded. Sans: I can tell you're getting really sick of trying. Chara: But I even come back after dying! Chara: Why not let me win, you can't dodge forever. Even if the pain is more fun together. Sans: I know you would just reset each time I beat'cha, but I'll always be right back here to meet'cha Sans: I know your. Chara: I am made. Both: O-O-O-O-OF LO-O-O-O-OVE LO-O-O-O-OVE Both: LO-O-O-O-OVE LO-O-O-O-OVE LO-O-O-O-OVE (Instrumental) Sans: This is where it stops, this is where it ends. Chara: You keep telling me those words and hope that I would understand. But even if I hear you, I won't give up my attack. Sans: Do you just like the feeling, of your sins crawling on your back? Chara: Go ahead, kill me again I see you're able. Sans: You should know by now that mercy's off the table. Chara: You think I might decide to stop if you stay patient. Sans: Well, you didn't spare my brother so get DUNKED ON! Chara: I know I made your friends all disappear. Sans: But every thing they cared about is why I'm here. Sans: I am their mercy. I am their vengeance. I am DETERMINATION! Chara: I'm entirely made O-O-O-O-OF LO-O-O-O-OVE Both: LO-O-O-O-OVE Sans: But I think I'm stronger than you. Chara: LO-O-O-O-OVE LO-O-O-O-OVE O-O-O-O-OVE I am stronger than you. LO-O-O-O-OVE LO-O-O-O-OVE O-O-O-O-OVE O-O-O-O-OVE O-O-O-O-OVE O-O-O-O-OVE Flowey: That's a wonderful idea.
