Muffet the spider

Muffet is greedy, stingy, intimidating and hypocritical, although with a courteous style of speaking. Even so, she seems malicious when she is crossed, something that occasionally triggers the encounter against her. Muffet has a tendency to make morbid or inappropriate statements, such as commenting on the protagonist's possible fate in being used to make food.

She has a restraunt she opened to get money to feed her spiders, and she noticed humans normally like porn, and innapropriate stuff, so she made it so she's always naked in her restraunt

Seeing as how she regrets letting Alphys go as opposed to using her as an ingredient, Muffet seems apathetic toward other monsters, with the one exception being spiders. Even during the Genocide Route, she still offers to spare the protagonist due to them "never hurt[ing] any spiders." Muffet's name appears to be referencing the children's nursery rhyme Little Miss Muffet, in which a young girl eating cottage cheese is scared away by a spider.

Muffet is an anthropomorphic spider monster with periwinkle or lavender skin, five eyes, six arms, and two legs. She wears red rompers with buttons in the front, a red ribbon across her chest, as well as twin pigtails in her hair. She is also shown holding two teacups with her top pair of hands and two teapots with her middle pair.

Her pet accomplice appears to be a giant muffin/cupcake with a face on the frosting part as well as spider legs sticking out of the sides, he also having big breasts, and big ass, and alot of curves

Her laughter sounds like "huhuhu~
