A monster owned by Undertale'sMuffet, only seen in battle when she calls it to try to eat the protagonist. It has no official name in-game, nor is its full body seen in-game (and its in-game depiction is not in color either), leading to a variety of nicknames and depictions, though the most common depiction is some combination of a giant spider and a cupcake or muffin; incidentally, its sprite is named "spr_hideouscupcake".
