The one of it's tail is shaped like a star and the part that comes out forms a heart. They also kind of look like those long dresses Primadonna singers wore. It's very cute overall.
The one on it's belly is obviouly there because it's a mermaid but also manages to introduce a selkie element because it loosely looks like it's shedding.
The one on its head reminds me of a crown and gives Primarina a regal and majestic look like Sea Lions have when they pose.
