After sans tells you to get behind the conveniently shaped lamp, you are expecting papyrus to appear, but instead a large photorealistic grayscale eye thats about 2 times bigger that papyrus normally is appears for some reason replacing papyrus. The conversation goes as follows: Sans: sup, bro? Prunsel: The eye doesn't say anything, except for a weird red light coming from the dialogue box. The background music completely cuts out too. Sans: staring at this lamp. it's really cool. do you wanna look? sans does not acknowledge what the eyeball is currently doing, and speaks as if he is still papyrus. the background music came back too. Prunsel: The eyeball does the exact same thing. The background music stops again. Sans: hmm... maybe this lamp will help you. sans still doesn't know what is going on. To him, everything is fine. The background music came back. It seems that when prunsel tries to speak, the music stops, but when they stop trying to speak, the music comes back on Prunsel: Does the exact same thing again. Sans: hey, take it easy. i've got a ton of work done today. a skele-ton sans winks Prunsel: Does the exact same thing Sans: come on, your laughing. Prunsel: Does the exact same thing Sans: wow, sounds like your really working yourself... down to the bone. sans winks again and raises his arms Prunsel: Prunsel has the same reaction, but this time they exit the area completely.. Sans: speaking to you ok, you can come on out now. He encourages you to come out from behind the lamp because Prunsel isn't there anymore.
