Toriel is a Boss Monster whose head resembles a white-furred Nubian Goat, structured with floppy ears and tiny horns. She has a pair of visible fangs and long eyelashes, and her irises have a dark red tint. She has an anthropomorphic body, with paws at the end of her limbs. She wears a long purple robe with white sleeves and the Delta Rune on the chest. Toriel can also be seen with reading glasses, when reading a book on snail facts.
