"Swim Suit" is the second segment of the fifty-ninth episode of Star vs. the Forces of Evil. It premiered on March 17, 2019 alongside "Moon Remembers", and is the second segment of the third episode in the fourth season.
While preparing to go to the beach with Marco and Tom, Star is called by Eclipsa, who reveals she got into a fight with Magic High Commission member Rhombulus, who created Globgor's crystal prison, to get him to undo the spell. Star attempts to get the two to peacefully reconcile, only for them to immediately start fighting again as soon as she turns her back on them. Eclipsa uses a spell that causes her and Rhombulus to switch bodies in order to undo Globgor's prison. However, Star convinces her to stop by pointing out that she will just prove herself the villain everyone claims her to be. Afterwards, Rhombulus angrily leaves, declaring he will never free Globgor, and Marco and Tom, seeing it is too late to go to the beach, make a kiddie pool to cheer Star up.
