Unique character design: Aqua Kitten

Backstory:
Bindi the cat went to the beach with her family. When they were there she met a fish and they became best friends. Bindi wanted to come home with the fish but she couldn't because she was a cat, and she can't breath under water. So the fish gave her a purple collar. And whenever Bindi wears it, she turns into aqua kitten. (half cat, half fish) Now Bindi is able to come along with the fish :D And they lived happily ever after.
