Great Scarrier Reef (TV special)

"Great Scarrier Reef" is the thirteenth feature length Monster High TV special and fifteenth overall. The name was revealed in a listing of copyrights owned by Mattel, and pictures of the featured dolls were leaked online in June, before being officially revealed at the San Diego Comic Con 2015. It will premiere in Spring 2016.

Story
Very little is known about the story at this time, other than it is themed around mermaids and merpeople. The Monster High ghouls will be transformed into mermaids, and three new aquatic characters will appear - Posea Reef, the daughter of Poseidon, Kala Mer'ri, a Kraken-like squid ghoul, and Peri and Pearl Serpentine, the two-headed daughter of the Hydra.

The teaser trailer previewed at San Diego Comic Con shows Lagoona Blue finally getting her Diver's License and inviting Frankie, Clawdeen, Draculaura and Toralei for a ride in the school's bottomless pool. Ghoulia, also wanting to take a ride, is disappointed to find that the ghouls already left. Lagoona attempts to find out whether the pool really is bottomless and wanders too deep into the pool. They get attacked by a kraken and the ship sprung leaks. Meanwhile, Ghoulia is shown listening to music near the pool, when suddenly Lagoona's ship appears. Ghoulia checks inside the ship and finds no one in there. She quickly wears a snorkel and dives into the pool.
