History
When Tsunami was still an egg, Webs stole Tsunami from the hatchery making her a Dragonet of Destiny. But when the dragonets got captured by Queen Scarlet when they escaped; they were put into a gladiator show where they had to fight another dragon. Tsunami had to fight the King Webs. Since he refused to fight other dragons Queen Scarlet took all water away from him making him crazed. This was before Tsunami even knew she was a royal heir and she killed her father.
What Webs and Tsunami didn't know was that inside the hatchery was a statue from Coral's unknown animus daughtor Orca who tried to get her mother's throne at a young age but died. But before she died she made a statue of her that would kill each one of Coral's decendants as a curse. Webs saved Tsunami from this. But Coral decided to protect her daughtors and saved Anemone (Tsunami's Sister) To figure out this mystery Tsunami investigated the hatchery and waited for the killer to come. The statue came to life and killed some of Tsunami's sisters and tried to kill her too but in the end Tsunami destroyed the statue and saved her last sister Auklet who hatched later that day.
But instead of staying in the SeaWing kingdom she had to go back with her friends to the Rain Forest Kingdom where they can take refuge from the SandWing Queens who want to kill them. At the end Tsunami becomes a teacher at Jade Mountain Academy with the dragonets. (Excluding Glory)
