Unicorn
Related to armadillos and rhinos, unicorns are a usually white horse-resembling creature with rainbow hair and a pink and purple horn. Have been mistaken to narwhals, but narwhals are actually unihippocampi. Not related to horses or pegasi, as they do not exist. A unicorn is quite real and one dies everytime someone breaks a promise, tells a lie, or has an awkward silence. Unicorns also have the power to grant you wishes.
