The trophy has a brother who is Balloon, his complete opposite. They don’t talk too much, but Trophy bickers Balloon a lot and acts more like a bully than a brother.
Nickel is a prince and clover is his sister princess, Nickel and Clover are also opposites. They don’t fight much but it’s sibling banter for the most part.
Trophy, Balloon, Nickel, and Clover have many interactions…their kingdoms are allies with each other. So they meet up together a lot.
Lightbulb is a princess, she acts a lot like Star from SVTFOE. She doesn’t really take her princess duties seriously, and her parents threaten to give the throne to another one of her sisters if she doesn’t behave. Since Lightbulb was scared she’ll never follow in her mother's footsteps in being the Queen, she tries taking a more serious approach the best way she can. Of course, she’s still silly and goofy, but she’s trying to take a lot more responsibility for her actions. She doesn’t like the idea of forced marriage, and she’s already set up to marry SilverSpoon, which she has a distaste for. She instead, made a deal with her mother that if she could find someone else by the end of Salt and Peppers's party to marry then she’d marry them. If not she’s stuck with Silver. So Lightbulb's goal during the whole party is to look for a Prince..or a princess..(she and her mom have not had the talk yet. She stumbles upon Painty, who she remembers meeting some time ago when they were kids. Lightbulb tries to converse but Painty just doesn’t seem to like her. Lightbulb is saddened by this and gives up..(not entirely.) She failed the deal with her mom and now she’s arranged to marry Silver, (Silver doesn’t really like her that much either.)
Fan and Tesstube are also living in Lightbulbs castle down at the lab, they help Lightbulb with something. (Which was a nice attraction spray for Painty to like her more.)
