You get a feeling when someone's going to choose to stay out there in their aquaticised form, and I think she's one of those people. She knew exactly what she wanted and became such an impressive whale shark mermaid.
Go check out my gallery for more Aquaticization transformations. That's people putting on special wetsuits that become a second skin as it transforms the wearer into something aquatic. They get to pick an animal that they'd like to become, and get to dive without gear.
