Lagoon is a plump, turquoise, female SeaWing introduced in The Lost Heir. She serves on Queen Coral's council and is in charge of preparing food for the council meetings. She was imprisoned by Queen Coral for neglecting the Dragonets of Destiny, but probably wasn't punished severely, according to Tsunami's guess in The Lost Heir.
After the dragonets were imprisoned, Queen Coral told Lagoon to make sure they were well fed. However, she only fed them small crabs and other breakfast leftovers from the feast that was served the council. When Tsunami found out, she told her mother. She also suspected the her uncle, Shark or even Queen Coral of being the one who gave the order for Clay to be chained, though it is still unknown who actually did this. Queen Coral seemed to be shocked and angry because they disobeyed her commands and had the two of them imprisoned, but Tsunami knew that they wouldn't be punished harshly and that they'd be soon released due to their status and role in the SeaWing government.
- It is suspected that she was eating the leftover food that she was supposed to be feeding to the dragonets.
- She shares a name with Queen Lagoon, the queen before Queen Pearl, who also shares a name with a present day SeaWing, Pearl.
