Star must learn how to free Marco from a magically locked closet without using her new wand.
Star makes a video stream on Marco's laptop, recapping the events of the previous episode, while Marco is in the shower. As she shows off her new wand, it suddenly begins vibrating and flying around the house before getting caught in the Magic Instruction Book and locking itself and a still nude Marco in Star's closet. As Marco dresses himself in the fabrics available, he and Star cannot get the closet door to open. Glossaryck arrives where he once again gives very vague advice to the teens. He tells Marco that in order to get out, he needs to find "Star's secret". Being that the closet is infinitely large, Marco dives in to look for it.
Meanwhile, Glossaryck converses with Star who is using a giant sword to break into the closet. He tells her, using a pot of stew as a metaphor, that in order for her to use magic to open the closet, she does not need the wand and can simply create magic on her own by going "dip down". Star does not believe she can do it, but Glossaryck bluntly tells her "your mom did it", much to her chagrin. Marco decides to organize everything in the closet, getting very little input from Glossaryck, while Star, who cannot understand metaphors, tries to open the closet with a variety of things. She calls her mother for advice, who is put off by the fact that Glossaryck is telling her about "dip down", and tells her that she needs to lose everything. Not understanding the context, Star literally tosses everything at the closet, impeding both of their progress.
Glossaryck begins looking into Star's wand to try and fix it and opens it up to see the horse running with glowing green eyes, which he identifies as not being good. He eventually directs Marco to a diary and begins to read it aloud, much to Star's horror. As Marco skims through it, he finds Chapter 11: Thoughts on Marco and attempts to read it. Overcome with strong emotions, Star "dips down" and unlocks the door, before grabbing the diary and hitting Marco over the head with it. Glossaryck returns with the wand apparently cleaned and has Star fire a spell. It creates another tower, but coats them all in green slime. As Marco states that he will get new pants, Glossaryck calls dibs on the tower.
