Unicorns

Unicorns are mythological creatures which make their first physical appearance in "The Last Mabelcorn". They play a trick claiming someone's not "pure of heart" to tick off humans.

Appearance
Unicorns are various colors, with manes usually of different shades of the color they are, with some exceptions where the manes are rainbow-colored. They also have a really long tail and they all have a white horn which glows with a different color for each unicorn whenever they talk.

Only three real unicorns are seen in "The Last Mabelcorn", with one having a white body, purple eyes with long eyelashes and a rainbow mane, another one with a magenta body, blue eyes and purple mane, and one with a teal body, dark green eyes and a green mane.

Trivia
Unicorns can't really look through people to see if they have a pure of heart, it's just a lie to get humans to leave them alone.
