Mermaid/Human Transformation[]
Merpeople are able to grow legs when they are dry, but if exposed to water will grow a long, blue tail. At low tide, wet or not, merpeople's tail will appear and they will be able to get their legs back at high tide. It is possible that the legs only have to be exposed to water in order for the tail to appear because June is seen sticking her hand in water at the marine park. Merpeople absorb anything that hinders the transformation like trousers, socks and shoes. They reappear when their tails become legs.
