List of Star vs. the Forces of Evil episodes

Star and Marco are trapped inside a tool shed by Ludo's army. As Marco tries to fashion something to fight them off, he recounts how he tried to cheer up Star because she left her phone number for her crush, a keytar-playing student named Oskar, but he has not called her back.

Star experiences "mewberty", that is, her skin breaks out in hearts whenever she is near boys. Although Marco thinks it's much like the Earthling condition, Star's is more extreme. She sprouts hearts all over her body, and transforms into a butterfly creature that captures boys and seals them away. Marco turns to the Glossaryck, a genie inside Star's book of magic, for advice on how to stop her.

After making prank calls on Star's magic mirror, Marco, Alfonzo, Ferguson, and Star must go to Pixtopia: Land Of The Pixies and pay the bill. When they can't pay it, they are forced to work in a mine shaft. The Pixie Empress flirts with Ferguson.

Star's ex-boyfriend Tom invites her to the Blood Moon Ball, an Underworld event that occurs once every 667 years. Tom claims he has turned over a new leaf, having hired an anger management consultant. Marco does not believe Tom has changed but Star decides to go anyway. When Marco disrupts Tom's plan to take Star for himself under the Blood Moon's light, Tom reverts to his old self.

Star freezes time with her wand so that Marco can appear at Echo Creek Academy on time for his morning greeting nod with his crush Jackie Lynn Thomas. But when she is unable to cancel out the effects, she and Marco visit the Plains of Time in order to get Father Time to restart time again.

Star gets an unexpected visit from her father who had been kicked out of the house for not picking up after himself. After getting excited over Earth activities such as using a flush toilet and playing miniature golf, he ends up overstaying his welcome. He hosts a party with his inter-dimensional friends, but it is soon crashed by a sun character named Helios.

Star and Marco go undercover as new princess students in order to break Flying Princess Pony Head out of St. Olga's on her birthday. They discover that Pony Head has been brainwashed to be a compliant princess and try to evade the robot guards and the reform school's headmistress Miss Heinous.

Guidance counselor Mr. Candle tells Star that she is fated to be Queen of Mewni. She has to read her mother's book on how to act like a queen but she gets frustrated and decides to dress up in a more rebellious punk style. Meanwhile, Marco, who is displeased of Candle's career suggestion of being the head janitor on Garbage Island, discovers that Mr. Candle is actually in cahoots with Tom, who planned to ensure "Starco" doesn't happen. He confronts Mr. Candle but is captured by Tom, and must duel Tom to get his freedom.

Star throws her wand by accident and it ends up in the mouth of a growling dog who refuses to let it go. She has to take care of the dog and find its owner. Meanwhile, Marco struggles to get a straw into his juice box and has to take care of the laser puppies. She eventually discovers the dog named Willoughby is actually a extra-dimensional being who didn't like life on her planet, so Star has her adopted by a strange lady named Lydia.

After getting a sugar high from seasoning her burrito, Star sets off some magic that accidentally causes a sign to fall and crush a police cruiser. While trying to evade the police, Star encounters a woman by the river bank named Brigid who likes making things out of hair and taking care of injured animals. She later encounters an underwater sea creature who tells her that hiding out is a good thing, but it is revealed the creature is actually her own conscience. Missing her family and friends, she returns to a very worried Marco and turns herself in to the police who have her wash the other squad cars as part of her police-supervised community service.

While foraging for donuts that are being tossed at the end of the day, Star encounters Mina Loveberry, a magical girl from Mewni who is Star's idol. Mina has been living as a homeless person on Earth. Star follows Mina and tries to train in her ways, which annoys Marco. At a park, when Mina announces she plans to take over the world, the people decide to hold a vote on whether Mina should rule, and Star is left to break the tie.

Star, Marco, Pony Head, and a bush-themed female named Kelly go to an unidentified dimension to purchase a Goblin Dog (a goblin version of a hot dog). They end up having a hard time when they must deal with the various jobs of the goblin vendor Roy and the many lines that lead to the Goblin Dog truck.

Tom invites Marco to a movie marathon featuring Mackie Hands, Marco's favorite kung-fu film star. They start to become friends on the way there after learning they both like Mackie Hands and a band called Love Sentence, but when Marco wants to leave to catch the marathon, Tom refuses to let him go, and gets angry, voiding his chance to earn an anger management graduation badge. Tom apologizes and tries to win back Marco with a Love Sentence song, and then raises Mackie Hands from the dead. Although they cannot get into the theatre, Tom and Marco watch Mackie lay a beatdown on the movie's security guards.

Mr. Diaz arrives to find Hungry Larry has eaten everyone, and rescues them.

Encouraged by Rock's words, Spider is finally called to fight a monster.
