Muffet is an anthropomorphic spider-monster encountered in Hotland. She runs a bake sale made for spiders, being very angry at passers-by who do not purchase anything from it despite selling overpriced items for 9999 gold. She's accompanied by multiple spider that dance at her will, and attacks those who are not fond spiders and are stingy with their money. Her pet accomplice appears to be a giant muffin with a face on the frosting part as well as spider legs sticking out of the sides.
