They rode into the tunnel and headed inside. They soon found themselves in the midst of the ocean.

"Wow... I've never seen the ocean like this before!" Pickle exclaimed.

They rode through the tunnel and headed to an opening, leading to the open ocean towards the kingdom.

"There it is!" said Windy. "Race you there, Spectra!"

"You're on!"

The two unicorns zoomed with a dash. Twiga and Iceheart stared at their comrades in bemusement.

"Wow... they're way more competitive than I thought," Iceheart only chuckled.

"Come on-- we better follow them before Blaze and AJ get whiplash."

They dashed off after the duo. They soon reached the the end of the tunnel, causing the two unicorns ahead to come to a stop.

"Whoa! You two got here fast!" AJ said, trying to catch his breath.

"You sure did. You guys better wait here while we talk to the queen." Crusher told the unicorns, hopping off.

"Uh, how are we going out of the tunnel? We can't breathe underwater," Pickle said.

"Good point..." Blaze realized.

"A little magic could do the trick," Crusher raised his hands and swirled his magic around.

In an instant, the magic surrounded them and carefully set them into the water. Their legs and tires shifted into tails of different colors.

"Whoa! Our legs and tires turned into mermaid tails!" AJ gasped. "And they're beautiful!"

"Now come on, let's get to the palace," Crusher told them, flicking his rainbow tail.

They made their way through the water, flicking their tails and swimming across the reef, which glistened in rainbow colors.

"Wow..."

They soon reached a great big coral palace behind a village of shells. Mermaids and different sea creatures of all kinds swam around as they swam through.

"Sooo amazing!"

They made it to the coral palace, where merman guards stood guard at the gate. They pointed spears at them at their appearance.

"Hey, hey, cool your fins!" Crusher said. "I'm Rainbow Prince Crusher, and we seek the mermaid you call Queen Lyna."

The guards exchanged glances before nodding and opening the gate.

"Thank you, kind sirs." Blaze smiled. "Come on, guys."

The guards gave a nod and watched as they swam into the palace and through the halls. They soon made it to the throne room. They headed inside to find a mermaid with a crown on her aquamarine hair. Her icy blue eyes stared down at them calmly while her lavender tail flicked.

"Wow... she's gotta be the most beautiful mermaid I've ever seen..." Blaze gasped lightly.

Crusher agreed with a nod before he swam forward with a bow.

"Queen Lyna, I am Prince Crusher of the Rainbow Kingdom, and me and my friends have come for the last of the four wands of heart."

"Truly?" Queen Lyna raised an eyebrow. "May I ask why?"

"The wicked witch Silla and her family froze the kingdom, and the four wands are the only thing that can undo the icy spell."

"I see..." Lyna gave a nod and swam up from her throne. "The wand is placed at the bottom of a trench, in the forbidden part of the sea. It would be quite difficult to get,"

"I'm willing to do anything to save my people and family," Crusher nodded firmly.

"And we're willing to help!" AJ agreed.

"Very well," Lyna sighed and flicked her hands, creating a magic bubble. "Use this and follow it to the trench, it would lead your way,"

"Thank you, Queen Lyna," Blaze smiled gratefully. "Your kind deeds will not go unnoticed."

"I know, and good luck,"

The magic bubble floated over out of the palace, and the group followed it off.

Back at the kingdom, Silla growled as she watched the group swim off to find the last wand.

"DRAT IT ALL!!"

She threw her crystal ball on the ground, causing Bruno and Tiilo to jump.

"Sister, if we combine our powers together, there's no way they could get past the next spell." Tiilo suggested.

"Fine... but it better be good." Silla grunted.

Their magic combined together before they released it into the air and towards the ocean. The waves of the sea began to grow stormy, all the way inside, creating a tornado under the water and towards the group.

"Underwater tornado, 3 o clock!"

They all shrieked as they swam off from the tornado. Another tornado was formed behind them, blocking their escape.

"AJ, can you use your wind power to stop them?!"

"I... I can try!" AJ raised his hands in attempt to stop them.

Unfortunately, it only managed to slow down the tornadoes before more came and appeared around them.

"I can't stop them! What do we do?!"

"GAAAAH!" Crusher screamed as a tornado caught him by the tail.

"CRUSHER!!" Blaze and Pickle shrieked.

The tornado forced him in before throwing him off, spinning out of control. He fell onto the seabed with a thud.

"Crusher! Are you okay?" Blaze questioned.

"Ugh, barely..." Crusher hissed and forced himself up before screaming when he almost fell into the trench nearby. "Now what?! We're trapped!"

He soon saw the bubble hovering over the trench, glowing brightly as it prompted him to follow it down.

"Follow the bubble! It's our only chance!" Blaze yelled.

Crusher nodded and swam down after the bubble which glowed brighter as they went deeper and deeper into the dark trench.

"Look, it's getting brighter! We must be getting closer!"

He soon found the wand glowing at the bottom of the trench. He reached out to grab it.

"Come on, come on… Aha!" He grabbed the wand and raised it. "Got it!"

In an instant, the wand made him float up a bit. His eyes flashed white as a swirl of icy blue magic entered him.

"Whoa..."

He heard screaming from above, and he swam back up at the trench to find more tornadoes around the others.

"I'm coming, guys!"

His eyes glowed icy blue before ice came out from his hands. He blasted one of the tornadoes, turning it into solid ice.

"Quick! Let's go!"

The others took the chance to escape, but the tornadoes came after them. Crusher growled and swam forward to face the tornadoes.

"Take THIS!!"

Ice struck more of the tornadoes, giving them time to get back to shore, where the unicorns were waiting worriedly.

"Woah! What happened?!" Spectra asked.

"We saw the ice and wondered where it was because Iceheart had been with us the whole time," Windy spoke.

"You all okay?" Twiga questioned.

"We're fine, and Crusher was the one who made the ice," Blaze said. "We have all four wands!"

"That's great!" Spectra cheered.

"We must get back to the kingdom now that we have what we seek," Iceheart told them.

"But how will we get there? It's so far away!"

"Blazing Speed could do the trick!" AJ cried.

His back opened up to reveal his boosters, which then spread around them as they hopped back on their unicorns.

"Leeeeeeeet's Blaaaaaaaze!!!"

With that, they zoomed across the beach and through the forest, heading back to the kingdom.
