Ash has been having a very horrible nightmare but it turns out that he was under a spell this whole time. The person that put him under the spell is no other than Ursula the sea witch. The dream that he has been having is he and his pokemon family are destroying his father in laws kingdom which happens to be Poseidon the great ruler of the lake happens to have 4 daughters. One of his daughters named Felicia lives on the island with him, but today is a very special day cause tonight is the mermaid's ball and it is going to be held at Atlantica. Ash wished that he can go but he can't because he wasn't born in the ocean. So in the meantime, he will just have a lot of fun with his pokemon family.
Meanwhile back under the sea Felicia and her family have been having a lot of fun at Atlantica. But Felicia has to keep her island life a secret from king trident cause he hates humans. But there are only 3 people in Atlantica that do know about her life on the island and they are Ariel, Flounder, and Sebastian. They have also been told to keep Felicia's island life a secret too. After that was out of the way Ariel takes Felicia to her secret grotto where she was amazed and wanted to know where she found all of these things. So Ariel takes her to a shipwreck during their visit there Felicia wanted to know more about humans. Now that she knows that there are other humans out there besides Jungle boys and she wanted to know more about them.
When Felicia was having fun at the mermaid's ball back on the island Ash couldn't get the dream out of his head it has been in his head all day and he wanted to know why he is having this dream in the first place. So as he was walking with Pikachu he spot two eels. Who said that they can help him but all they have to do is follow them and they know someone that can help him. So without thinking Ash follows them to Ursula's lair. When he got there he was really scared until he met the sea witch. Ursula told him that the dream that he has been having was a spell this whole time. After Ash learned that he bags her to take the spell off of him. But she will only be able to do that unless he gets her king trident's Trident but he refused because then Felicia and her family will never trust him again. So Ursula decided to give him a choice he can save his mermaid princess or his pokemon family. He picked either so instead of him hurting the merpeople or the pokemon he decided to let Ursula take him as one of her souls in her garden. At first, Ursula didn't want to do that but remembered that this boy is the son-in-law of Poseidon. It will be the perfect Bate for Poseidon once he sees his son-in-law in her garden he will have no choice but to give up his soul so that he can save Felicia's true love just so that she can be happy and with one kingdom underher power. Then she will have enough power to take down King trident's kingdom and she will be Queen of the whole ocean. So after some thinking, Ursula accepts his deal. Once Ash sign the contract once he was turned into a soul. Pikachu started to freak out and headed toward Atlantica so that he can warn Poseidon and Felicia about what Ash did.
At the Mermaid's ball, everyone was having a great time until Pikachu came in with horrible news. He told Poseidon and Felicia about what Ursula did to Ash. Then they told him to take them to Ursula's cave as fast as he can. When the king and Felicia got there. Felicia was horrified to see what Ursula did to her husband. Ursula told Poseidon that she will offer him a trade for Ash's soul for his. Felicia didn't want her father to do this but knowing that Ash makes Felicia happy he knows that he had no choice. So he signed Ursula's contract which turned into a soul and turned Ash back to normal. Now Ursula has power over Poseidon's kingdom now that she has one kingdom under her power now she can take over Trident's kingdom and then the whole ocean will be under her power. Ash didn't mean for this to happen. He just wanted to protect everyone and he didn't know that Ursula had bigger plans. Now that Poseidon is gone it is up to Ash and Felicia to save the kingdom but they are going to need some help. So they head back to Atlantica so that they can warn King trident and Ariel about what the sea witch did.
Felicia knew that sooner or later that it is time for king trident to know the truth and this could be the only way to save her father. Felicia and Ash got to Atlantica before Ursula did. Once King trident met Ash he was unsure about him because he was a human but after seeing him fight and how brave he was he decided to give Ash a chance. So after the battle with Ursula Poseidon turned back into a king. King trident allowed Ash to come to the mermaid's ball. But there is one more problem and that is ever since Felicia learned about there are other humans besides jungle boys she wants to know more. which is going to be a problem in the future.
This was starting to scare Poseidon and Ash about Felicia's safety. So he forbids her to go anywhere that is not close to the island and she is not allowed to go near other humans besides Ash cause he knows that Ash will never hurt his daughter after what he did to save her. There is no other human that will keep his daughter safe than Ash. Now Felicia is curious about humans and wants to learn more about them. Which will get her in real trouble with her father because he hates humans just as badly then Trident does. Still, there is only one human that he trusts and that is Ash. but with other humans, he will not risk putting his daughter in danger from them. So he forbids Felicia to go anywhere near other humans so that he can keep her safe But that does not stop Felicia from wanting to know more about the human world.
Will Felicia, Ash, Ariel, Sebiration and Flounder, and Pikachu be able to stop the sea witch before she destroys Atlantica? Will Ursula finally take over the whole ocean? Will Felicia's Fascination with humans get her in trouble with her father?.
