Meanwhile, the giant octopus was still trying to reach Ariel and Flounder while they stayed at the back of the cave. The eight-legged creature grew more frustrated by the second as it whipped its tentacle about, destroying stalactites and stalagmites left and right, causing rocks to fall or fly everywhere. At first, Ariel and Flounder feared an impending cave-in, but luckily, it didn't, the ceiling now bare.

"Must have run out of rocks," Ariel sighed in relief.

"Wish we were out of tentacles," Flounder gulped.

Ariel then looked at the rubble, and an idea bubbled up in her head. She then grabbed a large rock and heaved it at the octopus with all her strength, managing to hit its tentacle. The octopus roared in pain as it retracted its tentacle but was unwilling to give up as it reached for them again.

"It's not leaving!" Ariel huffed in annoyance. "And I thought my dad was stubborn."

She then kept throwing one rock after another at the octopus, hitting its tentacles repeatedly while the octopus took the damage but continued trying to reach for them.

"That's it!" cheered Flounder. "Give 'em one for me, Ariel!"

He then started passing rocks to his friend while she threw them one after the other. But as Flounder approached her with another piece of rubble, Ariel accidentally grabbed the tropical fish instead, believing him to be another rock, and geared up to throw him.

"ARIEL!" Flounder squeaked in alarm.

Luckily, Ariel stopped herself in the nick of time upon hearing him as she shyly blushed in embarrassment. "Oops. Sorry, Flounder," she apologized.

She set him aside and resumed her battle with the octopus, praying that Garret and Urchin would return with help soon.

Back with the two merboys, Garret and Urchin were swimming back to Shark Canyon.

"I just hope it's not too late," Urchin said aloud as they swam. "We've got to hurry!"

But as they went about their way, Garret couldn't help but still feel a little strange. He was still twitching with electricity while his tail sparked and crackled. The boy also began to feel a little feverish, which caused him to slow down.

"Wh-What's going on with me?" he thought. "I know I felt strange, but now I feel like I'm burning up."

Urchin then noticed Garret falling and was quick to go to him. "Hey, what's wrong, Garret? Pick up the pace!" he urged.

"J-Just give me a second, Urchin," Garret panted. "You're going a bit too fast for me."

Just then, Muray suddenly appeared. "Heya, kids. Something troubling you?"

"Oh, no. Not him again," sighed Garret.

"Sorry, but we don't have time right now," Urchin said to the eel. "We got to save Ariel and Flounder. They're both trapped at Shark Canyon by a giant octopus!"

"Is that so?" hummed Muray. "Then how's about I help you save your friends?"

"Really? You will?!" Uchrin asked, brightening up a bit.

"Hey, it's my fault," said Muray. "I'm the one who sold the poor girl the map in the first place."

"First sensible thing he's said all day," gruffed Garret. "But pardon me if I don't exactly trust your words." He turned to Urchin. "Listen, I wouldn't trust this guy as far as I could throw him. He's up to something."

"But he could also want to help us," pointed out Urchin. "He looks sorry and wants to make it up to us. He doesn't seem a bad guy, and we can use all the help we can get."

Garret sighed. "Looks like Ariel isn't the only one who's too trusting. But then again, I suppose it'd be nice to have a backup plan in case things go south with our original one, not that I had confidence initially."

"All right. I guess the least we could do is hear him out," Garret finally conceded. "But no funny business."

Muray grinned. "Glad you're on board, kid," he said. "Now come over here. I've got a plan. I have just the thing we need."

He then led the boys to his wheelbarrow, but as Garret and Urchin wondered what Muray had to help them, the sly eel threw something into the air, catching them both by surprise as they looked up. As they did, Muray grabbed Garret with his tail and yanked him out of the way just as a net fell right on top of Urchin, entangling and trapping him.

Garret was surprised, but before he could retaliate against the eel, Muray took out another item, a shell shaped like a gun, and pulled the trigger, releasing another net and trapping him, too.

"Hey! What's the big idea?!" cried Urchin, struggling to get free. "Let me out!"

"Shoot!" Garret also cried as he thrashed about. "I can get loose!"

Muray then went over to Urchin and tied his net onto a piece of rock, cackling smugly with glee. "The best deal I've ever made!" he spoke victoriously.

"Why, you slimy little sneak!" Garret snarled. "I knew we shouldn't have trusted you! Let us go right now!"

But Muray wasn't paying attention as he inspected Garret's tail. "Sorry, but no can do," he sniffed. "You're coming with me, kid. A merman like youse is going to make me a pretty penny. Never sold a merman before, but hey, no time like the present to start."

He gave Garret's tail a few pats of his tail, only for it to start crackling and sparking, which resulted in the eel getting heavily electrocuted, causing him to screech in alarm while convulsing.

Garret was surprised but humphed in satisfaction. "Hope you choke on it, jerk!" he said. "Now, you better let me go before I get mad and blast you! Although, on second thought, I should do that now!" He then held out his hands in front of him. "All right! Shoot!"

But nothing happened.

Garret then tried again. "Shoot!" he commanded while thrusting his hand out. "Shoot, I say!"

But still, nothing happened as Urchin and Muray stared at him. Garret looked at his hand, wondering what was happening, but suddenly, another fit of vertigo hit him, making him fall to his side on the floor, unable to get up.

"Garret!" gasped Urchin with worry. "What's wrong?"

All Garret could manage was a weak groan.

Muray soon recovered and saw the boy on the ground. "Sheesh. That power sure packs a wallop," he commented with a snide grin. "Tough break that you don't know how to use your powers, but I know someone who can figure them out."

He then tied Garret's net to his cart and went away, dragging him along while pulling his cart.

"Hey! Get back here!" Urchin yelled. "Hang on, Garret! I'll save you!"

Garret managed to weakly shout. "Urchin! Focus on getting yourself free first! Then go save Ariel and Flounder! When you do, tell them what's happened! I'll be fine!"

"But Garret…!" Urchin called.

"I said I'll be fine!" Garret interrupted with interjection. "I know you can do it! Just use that head like last time!"

And with those last few words, Garret and Muray gradually faded into the distance.

Urchin looked around, trying to find something to get free from the net. Then, his eyes fell upon an object on the ground. It was a broken seashell that came from Muray's cart.

The merboy grabbed the shell and sawed on the net using its jagged edges until he cut through it, setting himself free. And taking Garret's advice, he raced back toward Shark Canyon as fast as he could.

The octopus was still trying to catch Ariel and Flounder in its clutches.

At this point in time, it was able to reach a bit further inside, forcing Ariel and Flounder to move around to avoid its tentacles. Ariel still fought back by throwing stones but was running low on ammo, and if something wasn't done or if she or Flounder made one little mistake, they would be finished.

Then, Urchin returned to the scene, ready to help save his friends. He skimmed around the cave until his eyes fell upon a large boulder directly above the octopus, which gave him an idea.

He swam over to the boulder and began to push, trying to use whatever strength he had to knock it over.

"Come on! Come on!" he grunted. "Move!"

Urchin pushed and pushed with all he had until the boulder began to move, until it finally fell off his place. The octopus looked up, wondering what was happening, until it saw the boulder falling straight toward him. Not wanting to get crushed as it squealed in fear, the octopus finally moved away as the boulder hit the floor with an incredible crash, kicking up dust and scattered rock. The octopus swam away, not wanting to stick around any longer, speeding off fast as a sailfish.

Urchin was happy his idea worked but quickly called out to Ariel and Flounder as he swam to the opening.

"Hurry! Before he comes back!"

Ariel and Flounder were relieved to see Urchin and were about to depart the cave, but Ariel saw something that made her stop and swim to the back of the cave.

"Ariel, what are you doing?" Urchin called again in puzzlement.

His answer came from a bright and shining light blinding him and Flounder. That light came from Ariel, who carried three glow-shells, the source of it all.

"Sorry, I had to get these," panted Ariel with a smile as she put the shells in her bag. "This will be the best Father's Day gift Daddy''s ever had!"

Flounder could only sigh in exasperation. "Guess it'll be fin-warmers again for my dad," he said.

The three friends then left Shark Canyon. As they did, Urchin explained to Ariel and Flounder what had happened.

"By the time I got out, Moray the eel was gone and took Garret with him," Urchin finished. "But Garret told me to rescue you guys first and not to worry about him."

"Oh, boy. The king's going to be mad at you for messing with his trident," said Flounder.

Urchin wore a look of regret. "I know," he said with a hint of bitterness. "And I couldn't do anything to help Garret. Not to mention that I insisted he come along with me, and I didn't even know that something was wrong with him."

Ariel gave Urchin a reassuring touch on his shoulder. "Don't worry, Urchin. We'll find Garret," she spoke kindly. But even she was a bit worried. "Wherever he is."

But despite her worry, the little mermaid swam off determined to find her friend, and with newly found confidence, Urchin and Flounder followed her.

Moray soon returned to the Evil Manta's cave, presenting Garret while explaining his alleged powers and what he had seen. While he did, the Evil Manta held Garret by the net, inspecting his body with his evil eyes, particularly at his tail.

"Listen, Manta, I'm a moray eel, but in light of these circumstances," Moray spoke nervously. "I decided I didn't care to be an electric eel."

"Smart choice, Moray," the evil manta chuckled with a smile. "Thanks to you, you've given me what I need to take the world by the tail."

Moray gulped. "I, uh, I'm glad you approve," he said timidly, choosing his words. "So, what'll you give me for the kid?"

The Evil Manta leaned in close as he leered maliciously. "How about your life?" he said with a sadistic purr.

Moray gulped as Fangs barked at him ferociously.

"I can live with that!" he sputtered.

And not wanting to stick around any longer, the eel swam away, taking his wheelbarrow.

The Evil Manta laughed as he petted his dogfish with affection.

Garret, while still weak yet conscious, spoke out. "Well, you're as charming as ever, Manta," he spoke gruffly. "You must be a real gas at parties."

The Evil Manta looked at Garret. "I must admit, you're quite brave given your situation," he said. "But it doesn't matter how brave you are. I have big plans for you."

"And what would those be?" Garret continued to speak feebly but with courage. "You plan on using me as a hostage? Or use me as a weapon? In case you haven't noticed, that didn't exactly work out the last time you did. And also, I don't know how to use these powers, so you're wasting your time."

"Oh, I'm well aware, but I have ways to get what I want," the Evil Manta purred as he turned Garret's net with a finger. "And with the power that you have stored within your body, I shall take my time taking that power for myself and using that power to crush King Triton and have the entirety of Altantica bowing before me.

And with a fiendish cackle, the Evil Manta swam back to his cave, taking Garret with him.
