This new Monster High character is double the trouble -- and the sea-sational fun! The two-headed daughter of the Hydra, Peri and Pearl are twin sisters who may have their own minds but not their own bodies. At least they agree on humor -- their interactions are always entertaining! When the Monster High ghouls get pulled down under to the homeland of Lagoona Blue in the Monster High Great Scarrier Reef movie -- they find themselves underwater where they meet these sisters and beasties. The two-headed creature has cool glow-in-the-dark bioluminescent effects in the fins and a scaly tail that curls so the two girls can make one stand -- if only they could agree. A colorful top has an iconic print, and the accessories are twice as nice for the bling-loving duo. Fans of the movie will love recreating scenes or playing out new adventures.Collect all of the Monster High Great Scarrier Reef dolls for an ocean full of Monster High ghoulfish (each sold separately). Includes two-headed Peri and Pearl Serpentine doll wearing fashion and accessories. Colors and decorations may vary.
