"Mewberty" is the first segment of the sixth episode of Star vs. the Forces of Evil. It premiered on June 15, 2015 alongside "Pixtopia".


When Star starts sprouting hearts all over her body, the telltale sign of Mewberty, Marco searches for a way to keep her from losing control.


Marco and Star are about to leave art class when Marco notices a paint stain on Star's forehead. However, Star explains that it is not a paint stain but a heart spot, one of the first symptoms of Mewberty. Marco at first sees it as no big deal since everyone on Earth goes through a similar phase in their lives but Star tells him it is far more different than Earth puberty and could potentially destroy the school. Marco decides to take Star home, but already she begins to show an urging attraction to all the boys she passes and sprouts more hearts all over her body. She also develops the ability to creating purple sticky webs from her hands. Worried that she might harm Marco, she locks herself inside a school locker. Marco suggests checking Star's magic book and see if there is a way to stop her Mewberty, but Star says that she lost it in a bet with Ferguson.

Marco finds Ferguson in Spanish Class, and when he asks for Star's book, Ferguson tells him he gave the book to Janna. Marco soon finds Janna with the magic book and begins to search for a page on Mewberty but finds a little guy named Glossaryck instead. At first, he refuses to help Marco as he only serves princesses, but reluctantly volunteers to help him if he can provide him with some pudding. Meanwhile, Star is still hiding in the locker and manages to peal all the hearts off her body but more soon grow back when students pass by her locker. Her skin turns purple, her eyes begin to glow and now has an uncontrollable passion for boys. The locker she is in soon begins to overfill with hearts and form a heart-shaped cocoon. Eventually, Star emerges from the cocoon with six arms and wings.

While feeding Glossaryck pudding, Marco asks him how he can stop Star's Mewberty. Glossaryck tells him it is a natural process that cannot be stoped, but he assures that she may (or may not) return to normal. Suddenly, Marco hears a scream and goes off to check it out. The weather turns dull when Marco discovers half the school overgrown in purple hearts and vines. He also finds a number of boys trapped in purple webbing and soon finds Star about to wrap another boy in her web. Marco tries to reason with her, but Star ignores him and continues to wrap up her new captive. When he tries to interfere, Star reacts by wrapping him in her web until she hears Oskar's music. She attempts to wrap him in her web as well until Marco catches her in a tennis net. Marco holds tight to the net as Star tries to break free and begins to drag Marco all around the school. Glossaryck tells Marco that he is only making things worse by interfering. Finally realizing there is nothing he can do, he reluctantly lets Star go, who grabs Oskar and carries him up into the clouds. Suddenly purples hearts fall from the sky and Oskar and his car land safely with a returned to normal Star also falling and landing in the hearts. She sees that she has small wings and attempts to fly with them and Marco, but they fall with a thud.
