New characters appear that I wanted to introduce. Starting with this character. And yes, Dolphina has an orca as a sister, and her name is Delta.

Delta is a orca and she is Dolphina's younger sister. The small difference is that Delta is a bit bigger than her dolphin sister. Delta loves her sister Dolphina very much, although sometimes, when she hugs her, she suffocates her a bit because of her strength. ^^;

Delta is quite friendly and loves meeting her sister's friends, especially her friends Lara, Bianca, Alice and Luna. Like Dolphina, she is also quite intelligent and likes to help others in case help is needed. Delta visits Dolphina from time to time thanks to another magic necklace she found while exploring an old sea ship.

The reason Dolphina has an orca as a sister is that both orcas and dolphins belong to the Cetacea and Delphinidae families. That's why I thought it would be an interesting idea to have Dolphina's sister be an orca.
