Princess Neptuna

Princess Neptuna is the long-lost daughter of King Neptune and Queen Amphitrite and the sister of Prince Triton and Princess Mindy. She makes her debut in SpongeBob and the Long Lost Princess.

Bio
Princess Neptuna was born to Amphitrite and Neptune, who, with Triton and Mindy, were overjoyed at the little girl's birth. The whole family sent a shooting star into the aquatic sky to celebrate it for all to see. But that night, their joy shattered. Eris, goddess of chaos, who wanted to take the child so badly for her youth, sneaked into the king and queen's bedroom. The couple was asleep, and they weren't expecting what was to happen to their baby girl. Eris sneaked over to the crib and carefully took the little infant out. But little Neptuna started crying. Quickly, Eris disappeared with her in a swirl of black smoke. Amphitrite woke up quickly (thanks to her mom senses) at her daughter's crying, and seeing the crib was empty, she screamed so loudly, it woke the entire castle. Both father and mother mourned over their daughter's disappearance. Back at Eris' lair, Eris raised the little goddess as her own, renaming her Lindsey. Neptuna was told to never go out of the lair, and her heritage with her parents was kept secret. But thanks to SpongeBob, she was reunited with her family.

She developed a relationship with Jeron, Triton's best friend, but with the laws of the gods about sea and land not linking, they had to secretly go out. But when Neptune found out and banished Jeron, Neptuna was heart-broken. However, Jeron came back thanks to Sandy and Jervis and took her to Rock Bottom. Unfortunately, Neptune noticed Neptuna was missing and found them. When Neptune and Jeron were about to blast each other, Neptuna stood between them and got hit. In the sequel, she died but was revived by Jeron. After SpongeBob and his friends found them, Jeron gave her back to them, not wanting her to end up like his mother, who went through the same fate she did. After Eris attacked her again, Jeron nursed her back to health after defeating Eris with Neptune and Amphitrite's help. In the end, she and Jeron married.

Looks
Neptuna is similar to her mother (face shape, eyes, skin color, and nose) but has some features from her father (hair and tail color). Her hair is red and wildly curly. She wears a simple magenta top and a white rag around her waist. She is very beautiful despite her dress code. When she was reunited with her family, she wore a light pink top more suited for a princess.
