"By the expression on your face, we can tell that you know who Hexxus is." Tech said, noticing her expression.

"I do... I didn't think he'd ever come back after what I've been through..." Cherry sighed. "That monster..."

There was deep, dark, diabolical laughing heard. 'Hello, Cherry... You've grown up so fast...'

"Leave me be, Hexxus, Katie's not here for you to manipulate anymore!" Cherry scowled as they all heard a dark and scary voice talk with the just as morbid and depressing woman.

"Leave her alone." Atticus said.

'Oh, I don't think I will...' Hexxus cackled. 'If I can't take over FernGully, then I will take over Acmetropolis!'

"STAY OUT OF MY LIFE!" Cherry snapped while Hexxus laughed as he was the one polluting the land when Adolpho believed humans had done it.

"I think it's time that Adolpho found out the truth." Atticus said.

"If you can get him to listen..." Cherry snorted in slight disbelief.

Nebula and Estelle tried to heal Adolpho, but it wouldn't work.

"Why isn't this working!?" Estelle cried out.

"There must be some other barrier protecting him!" Princess Nebula suggested.

They then saw Atticus and Mo swimming over to them and Adolpho in their merperson forms.

"Mom, Dad, nothing's working, we can't get Adolpho to stop!" Estelle alerted her parents.

"It's because Hexxus must be protecting him from being cured." Atticus told their daughter.

"What can we do?" Estelle frowned.

"The only way to wash out pollution, also the fairies need to rid of him." Princess Nebula explained.

"Do you know how to contact these fairies?" Mo asked.

"Indeed I do, hopefully they can make it in time before Acmetropolis is doomed." Princess Nebula replied before swimming off.

Estelle clung to her parents, very worried.

Princess Nebula swam and came to the surface of the rainforest's waters.

A blue glow came to her and a short black-haired female fairy came to her. "Princess Nebula, what is it?"

"It's Hexxus, he's back and controlling Adolpho to sink Acmetropolis, you and the others have to stop him, Crysta!" Princess Nebula commanded.

"We'll be there right away." Crysta said.

"Please hurry!" Princess Nebula urged.

Crysta nodded and rounded up the other fairies to tell them about Hexxus's unfortunate return. Once she had told all of the fairies, all of them flew off to defeat Hexxus hopefully this time for good.

"Help is on the way." Princess Nebula told her new friends with a smile.

Hexxus laughed as there was so much chaos and he felt so empowered. Adolpho had victory too as he rounded up more whales to help. However, Crysta used all her magic with her fellow fairies and they zapped the whirlpool. This made a big explosion and the whales and dolphins flew out of the water and were now slowly coming back down.

"NOOOOO!" Hexxus snarled as he was defeated once more.

Crysta glared at him and took out a staff given to her by the Magi and she started to fight him like a trained sorceress.

"Wow, a real fairy." Mo said.

"Have you ever not seen a fairy?" Princess Nebula looked back at Mo, still surprised.

"No, never, not once in my life." Mo said.

"Your family needs to get out more..." Princess Nebula commented.

Crysta banished Hexxus with one final blow and the fairies could now celebrate. As of right now, Hexxus was dead.

"I'm so glad he's gone now..." Cherry whispered as she bowed her head with her eyes shut based on past experiences with the evil, living smog cloud.

"This is making me very upset!" Adolpho groaned once he was caught in a net and brought back up to the ship.

Estelle, Atticus, and Mo came back up to the surface and changed back into their humanish forms while Princess Nebula waited for them in the water. Estelle was now able to cure Adolpho now that Hexxus was gone.

"Now, before anything else, whatya say ya cough up our pals, Moby?" Ace glared at the whale.

The whale then spouted out Rev, Akito, Vincent, and Slam for them to end up back on deck with the family and the other Loonatics.

"That was being close!" Felicity commented.

"And where were you, young lady?" Cherry glanced at her daughter.

"I got lost..." Felicity admitted.

"How did you get lost?" Vincent asked.

"I guess I went to another way..." Felicity held her hands out.

Cherry picked her up. Felicity took her Atlantica trinket off, which made below her waist turn back into her pale feet and Cherry lowered her into her black boots.

"Hey, this isn't part of the plan!" Adolpho snarled.

"You gotta play by our rules now." Ace smirked, folding his arms.

"That was really wild, it felt just like in Pinocchio!" Rev zipped around once he was free once again.

"Yeah, only inside, we were shot out through the blow holes." Akito said.

Rev then had another rant, mostly about why it's called the cat caught the tongue.

"Now, what to do with you?" Vincent looked to the bad dolphin.

"Shall we take him downtown?" Akito added with an evil smirk for the villainous animal.

"This isn't over!" Adolpho snarled at them.

"I'm sorry, but you need to be taught a lesson." Princess Nebula told Adolpho.

"Yeah." Estelle added in.

"We'll take him off yer hands, you are free to go back home, Princess Nebula." Ace told her.

"I'll never forget any of you..." Princess Nebula smiled, she then took out a silver conch shell that had jewels around it and she took a deep breath and blew into the shell.

Something magical happened and they all looked to see several mermen and mermaids return to the sea after Adolpho had been defeated.

"My fellow merpeople, peace has been restored!" Princess Nebula told them all. "We can all now rest in our home back under the sea and I will make you all one proud queen when I grow up! But I couldn't have done it without my new best friend..." she then smiled softly, looking back at Estelle in gratitude.

Estelle smiled back.

"Well, we're gonna take Adolpho back where he truly belongs," Lexi said to the Fudo family and Cherry with Simon. "It was really nice to meet you all, especially you, Mrs. Fudo."

Mo smiled back. "Likewise, Lexi."

"I really wish that we had brought Patch with us." Vincent said.

"Maybe another time?" Ace suggested.

"We'll have to see, thanks for the ride, it was really enjoyable." Mo said to them as they took their portal home.

Simon even waved to the Loonatics, but still frowned a little as he was carried in his mother's arms.

"Arrievous, dauphin!" Felicity told Adolpho.

Princess Nebula smiled to them as they went off and she with the other merpeople of the future waved to the departing heroic family.

"Wait, after the mission, me and Ace were going to train." Akito remembered.

"Come home for dinner though, after that, you can stay with your friends again." Mo promised.

Akito sighed, but he did agree. "Okay, Mom."

"Have to make a stop at the prison first." Ace was eager to train with the boy again.

"I think the prison is the right place for him." Duck said.

"Yeah, in a giant fish bowl!" Tech agreed with a laugh.

The families left back home while Akito would stay until dinner time.

"A giant fish bowl does sound great." Akito smirked.
