Muffet

Muffet is a supporting character in Undertale. She is a baker that sells spider-themed pastries for unusually high prices (9999 gold), but for a good cause. She serves as a sub-boss towards the end of the game.

Appearance
Muffet is an anthropomorphic Spider-Human hybrid. While her form resembles a human, she has six arms and two legs, making a total of eight appendages similar to a spider. She has bluish-purple skin, five eyes, fangs, and short black hair tied into pigtails by pink ribbons. She wears and elegant red dress with pink bloomers and black boots.

Personality
Muffet is notably calm, especially after learning of a human in the Ruins killing her spider friends. On the other hand, if she sees the protagonist holding a spider pastry that she did not witness them purchasing, she may accuse them of stealing it.

Despite her somewhat creepy appearance and the high prices of her goods, she is actually a very charitable individual. She wants to earn enough gold to purchase a heat-insulated limousine to transport the spiders living in the ruins across the Snow Village safely to get them to reach her headquarters in Hotland.

Role
The protagonist first encounters her in Hotland after defeating Undyne. There, they will notice that she has set up a stand to sell spider pastries. If asked what she is doing with the gold she earns, she will state that she is trying to save enough to purchase a heat-insulated limousine to rescue the spiders living in the Ruins to get across the Snow Village safely.

Later on, the protagonist will enter her headquarters. There, they will her her echoing voice state that there is a human wearing a striped shirt on the loose killing spiders. The protagonist will then become trapped in a thick, sticky web and become unable to escape, there she will appear and battle the protagonist, thinking that they are the human that hated spiders. She will attempt to feed them to one of her pets for dinner, but will be interrupted by a telegram stating that the protagonist is not the one who hated the spiders. She releases them, although the protagonist has the choice to either kill or spare her. If she is spared, she apologizes for the mishap and invites them to return anytime.

If she is visited anytime afterwards, she will state that her fundraiser was a success.

In the True Pacifist Ending, she is seen among all the other creatures and characters the protagonist spared, cheering them on in an attempt to defeat Flowey.

Trivia

 * Her name, as well as her spider appearance are a clear references to the classic nursery rhyme Little Miss Muffet, in which a girl is scared away by a spider.
