While little is known about their personality as few of them actually talk, the Sprixie Princesses are known to be good and kind characters. Their personality can be extrapolated from stamps and birth from oldest to youngest.
The Green one (Clover) seems to be more of a leader. She is peppy, bright, curious and open to new faces. Clover seems to be more of a protective parent towards her sisters.
Yellow (Honey) seems to have fits of sadness and depressed in her stamp image, yet deep down inside. But she is intelligent, confident and brave. In her artwork, she appears to be flirty, but cheerful. She always goes to risky things.
Blue (Crystal) seems to get short-tempered and a headstrong tomboy-ish her stamp and artwork, but in-game she is more cheery and graceful.
Orange (Pumkin) seems to be very cheery, exciting and happy-go-lucky in her stamp image. She is also shown making a "wow" pose in her artwork.
Purple (Moana) seems to be contemplative and vanity in her stamp. She can also assumed to be a planner.
Cyan (Skye) seems to be scared and shy in her artwork, and she is portrayed as easily surprised in her stamp.
Red (Reese) is shown as scared in her stamp, but she may actually be a courageous, energetic tomboy.
At the start of the game, the Sprixie Princesses are trapped in bottles but are freed when Mario, Luigi, Princess Peach, and Toad (Super Mario Bros.), visits their planet via a clear pipe and breaks them out of their bottles. Bowser captures them again and uses their power to make his theme park. Mario defeats him again and the Sprixies, Princesses, Commoner, and all, are freed once more.
The Green Sprixie Princess also appears as a playable character in Mario Tennis: Ultra Smash.
