"Hello, dearies. My name's Muffet. But you already knew that, didn't you? Ahuhuhuhu~ Of course you did. But I have to have a good first impression, right? No matter. I better not get sidetracked. My name's Muffet, I'm setting up a bakery on the surface, and y'know! All that stuff. I'm getting bored of talking like this, let's spice it up!
The rules are simple. Keep it CS appropriate, an NO KISSING! If you violate these rules, I will resort to my old ways, kill you, rip out your soul, and give to Mettaton. Ahuhuhuhu~ I'm just kidding! But your face, priceless! Please just follow the rules. Thank you, dearies.
Just saying, I haven't been on the surface for long, so I might not know about your human thingies. With that out of the way, let's go!"
*Muffet's eagerness and optimism fills you with DETERMINATION*
