While impersonating the Dream Princess, she caused around fifty disappearances, using a red mist from her mouth to put them into a dream state where their energy would be taken from them. When the Sailor Scouts confronted her, she gave Sailor Moon a wreath, which was intercepted by Sailor Mars, turned into a snake, and bit her on the arm, beginning to turn her to stone, but with her scroll attack, Sailor Mars stopped the curse.
This is the first time Sailor Moon and Sailor Mars combine their attacks.
In the original Japanese version, the background music used in the scene where the Dream Princess is confronted by Sailor Moon and Sailor Mars and her headless body was spinning around like a music box was a random "music box" tune. In the English dub, a more appropriate piece of music is used, "Brahms' Lullaby".
The "Dream Princess" drains the energy of the park guests.
