Before I talk about Miss Heinous, let’s discuss the “Grandma Room” or the Tapestry Room as the book, Star and Marco’s Guide to Mastering Every Dimension, called it.

The Grandma Room (I’m going to call it that for now on) was introduced in Into the Wand. It’s a room filled with tapestries of the past queens of Mewni, Star’s grandmothers. Sure, the tapestries are interesting, but there’s something else that’s more interesting.

Notice how much the heart, the diamond, the spade, and the club are emphasized in the room? They’re even on the bottom of the wall! They represent the four suits on playing cards, but why did they put so much emphasis on those four marks?

The heart, the diamond, the spade, and the club are the most important and most powerful markings. Three of the marks belong to the most powerful queens and a princess: Star (hearts), Moon (diamonds), and Eclipsa (spades). But what about the clubs? Let’s discuss the owner of the club marks.

Miss Heinous

Miss Heinous was first introduced in season 1 in the episode, St. Olga’s Reform School for Wayward Princesses. She appears as just an ordinary antagonist for Star, Marco, and Pony Head, but towards the end of the episode, there was more to her than meets the eye.

(Note: I’m sorry the image is so big. I don’t know how to make the image smaller, so I’m just rolling with this.)

Yes, Miss Heinous has clubs on her cheeks! The book confirmed that only the Butterfly family have the cheek marks, so this means Miss Heinous has ties to the Butterfly family. She chooses to hide the connection by hiding her club marks through brainwashing herself or using make up to conceal them.

When she was giving her speech to the princesses, she said “Mewni” in a rather disdainful way. She also froze one of Star’s hearts.

Could she had used magic in that moment? I guess she never used magic in fear of people connecting her to the Butterflies.

But why all the secrecy? Why is Miss Heinous trying so hard to get rid of her and other princesses’ individuality?

Theory: Miss Heinous the Forgotten Princess of Mewni

Miss Heinous was once the princess of Mewni, the older sister of Comet Butterfly, Moon’s mother (that’s her official name). However, the pressure of being a perfect princess and queen had gotten to her, and she ran away before her sister was born or when she was too little to remember her.

After failing to find her, Miss Heinous’s parents decided to forget about her and make Comet the new princess of Mewni. They’ve never told her she had a sister and, as time went on, people completely forgotten about Miss Heinous.

After everyone forgotten about her, Miss Heinous changed her name (I doubt “Miss Heinous” was really her name), and built St. Olga’s to make sure princesses are perfect so they don’t succumb to the pressures of being queen. However, she slowly lost bits of her sanity herself and when Princess Marco showed up and ruined everything she built, she finally snapped.

Note: In the Grandma Room, the star is in the middle of the heart, the diamond, the spade, and the club on the ceiling. The star is also on top of of the door where the four markings are. I wonder if it has any significance and if so, does it apply to Star?
