It was a peaceful day since the Christmas celebration in the Equestrian Isles in Skylands. In the Canterlot Portal Chamber, three Water Skylanders, Gill Grunt, a gillman marine armed with a Harpoon Gun, Wham Shell, a King of a kingdom in the oceans of Skylands, and Zap, a Water Dragon Prince who was raised by electric eels, entered the chamber and attempted to use the Portal of Power to get to Skylands.

"Ok, so we know that Celestia and Luna use the portal for transportation to Skylands." said Gill Grunt.

Wham Shell spoke, "But they also use it to observe other worlds."

Zap replied, "If we can work the coordinates we could be able to get us to Skylands without ending up in another world."

As soon as they set the coordinates, they stepped into the portal but felt that it did not feel right. But before they could step off, they were flung to parts unknown, Gill Grunt yelled,

"Grab hold of me, so we don't get separated!"

The two Skylanders held on to Gill Grunt as they fell into an unknown world. They passed a ship, which made one of the sailors jump in shock,

"I must be seeing things."

That sailor was approached by a black haired man, white shirt, blue pants and black boots,

"What do you mean?"

"I saw a streak of blue light and a sound of screaming. I hope the king of the sea will still be in a friendly type mood."

Underwater, the Skylanders released each other, looked around and Wham Shell asked,

"Gill, what just happen?"

Gill checked his Portaltrix, given by Spyro as a Christmas present, "Somehow, we screwed up and we were sent into one of the worlds, that the Princesses observed."

Zap asked, "But where in this world are we?"

Gill Grunt replied, "Well, according to the Portaltrix, we are in the middle of an ocean known as the Atlantic."

Wham Shell readied his mace, "Guys, I think I saw something." Gill Grunt readied his Harpoon Gun and Zap readied his electricity pack to chase after the unknown.

They followed it into a tunnel and they began to see more of them...half-human, half-fish. The Skylanders saw hundreds of those creatures gather at a beautiful golden castle, and saw them gather at a concert hall. Gill Grunt stuttered,

"M..M..M.M..Merpeople."

Zap responded, "Holy Carp!"

Wham Shell lowered his mace, "It looks like a concert is about to start."

The Skylanders swam to the front row, got confused stares from the other merpeople. They saw a small seahorse annouce the king of the Merpeople, and the composer for the concert. The King was holding a trident, that was charged by his position as ruler. Wham Shell thought,

"Was that thing passed down from the last king like my mace?"

The composer is what made Gill Grunt ask, "Isn't that a crab?"

Zap licked his lips, "Well, it would make a good meal for me." Wham Shell smacked Zap, "OWWW, WHAM SHELL!"

Wham Shell said, "Really!?" The Water Dragon rubbed his head, "Can't you just take a joke?"

As the concert started, that same crab 'Sebastian' started the music as three clams rised and opened, revealing two mermaids in each clam. Gill Grunt did the math and there were six mermaids performing until they announced a seventh performer. A fourth clam raised and when it opened, the crowd, peformers and composer was shocked, and not because Zap accidentily zapped the crowd and the composer, the diva wasn't there. Gill Grunt signalled,

"Now it would be an excellent time to leave before we face the King's wrath." Gill Grunt sped away, Zap replied, "I'm with ya, Gill." Zap left, and Wham Shell spoke, "Its going to get crazy, Lets go!"

Back in Equestria, Aloe and Lotus were wondering where Gill Grunt is. The twins spoke to any Skylanders who know about his whereabouts. Until they spoke to Chop Chop, Stealth Elf and Thumpback, Chop Chop realized,

"Come to think of it, we haven't seen Wham Shell or Zap anywhere."

Aloe asked, "Then they must've wandered off."

Thumpback spoke, "Gurglefin thought that he saw the three heading for Canterlot."

Lotus asked, "Who?"

Stealth Elf described, "Gurglefin is a Gillman that we saved in Skylands. He's mostly his finman, because they always seemed to get along."

Their conversation was cut short when Flashwing landed, "Guys, I think our Portal Masters know where those three are. We got a signal from the Princesses, that Gill Grunt, Wham Shell and Zap used the Portal of Power recently. They want us in Canterlot immediatily."

Aloe spoke, "You better make sure Gill Grunt is okay."

The Gem Dragon spoke, "There's also a PS here, The Princesses want the Spa Twins to come to Canterlot castle. She finds both of you worthy and are ready."

When the Skylanders arrived at Canterlot, they were quickly escorted to the Portal Chamber where all Skylanders assembled. Princesses Celestia and Luna sat behind the Portal levitating a vial of the Skylanders Serum. The Spa Twins were shocked to discover this, Aloe started,

"Are you going to?"

Lotus finished, "Make us into Skylanders?"

Princess Celestia spoke, "You two might be owners and groomers of the Ponyville Spa, but you have abilities, unlike any other Earth Pony with the acception of Applejack and Pinkie Pie. Will you become Skylanders?"

The Spa Twins looked at each other and nodded, "We accept, but there's only one vial."

Princess Luna corrected, "You two are more powerful when you are united. So when you each drink half of the serum, you both become Skylanders."

Spyro stepped forward, "The first tag-team Skylanders."

The Spa twins drank the Skylanders Serum, Aloe went first, Lotus went next. Both soon felt their hidden ability and say their battle cry,

"WASH AND BOOM!"

After they said it, they began to glow. They became Lightcore Skylanders for the Water Element, and became Skylanders.

After the initiation, Princess Celestia turned her attention towards the Portal of Power and said, "Let us know where the missing Skylanders are, so we could know if they are ok."

The Portal came to life and an image appeared with the three Water Skylanders swimming to a rock.

In the new world, The Water Skylanders breached the surface and swam to a nearby rock, Zap spoke, "Whoa, That was close!"

Gill Grunt responded, "What kind of a crowd panics when the star of the show goes missing?"

Wham Shell replied, "A Wacky one, thats for sure, Gill."

Gill looked up, "Hey look, a strange seagull holding a spyglass."

The seagull was playing with a spyglass which got a confused look in the eyes of the Skylanders, until he heard a female voice,
"Scuttle!"

The seagull 'Scuttle' yelled, "Whoa!" pointing the spyglass the wrong way and frightening Zap, making him fall into the water which made Gill and Wham laugh.

Zap angrily said, "Ha Ha, real funny guys!"

Wham Shell cleared his throat, "Are you all right, Zap?"

Scuttle yelled, "Mermaid off the port bow! Ariel, How ya doing kid!" He lowered the spyglass and noticed the mermaid in his face, "Whoa, what a swim!"

The Mermaid noticed the three Skylanders, "Oh hi there, I never seen you three around. My name is Ariel."

Zap spoke, "Nice to meet you Ariel. I'm Zap, and this is Gill Grunt, and Wham Shell."

The Mermaid's friend, Flounder spoke, "Ariel, these guys kind of scare me."

Wham-Shell thought, "Well, at least he didn't say we were creepy."

The Mermaid now began show Scuttle what they found. The stuff that they found was something the Skylanders recognize. But Scuttle took a fork that Ariel showed him and dubbed it 'Dinglehopper'

Zap whispered, "Say What?"

Scuttle went on how this 'Dinglehopper' straightens hair out. Gill Grunt whispered to his fellow Skylanders, "That bird is Cuco in the bird-brain." Wham-Shell correctted, "Or misguided if you tell me."

Scuttle now began talking about a pipe called a 'Snarf-blatt'

Back in Equestria, Thumpback was a little confused about what that stupid Seagull was saying.

"Dinglehopper? Snarf-Blatt? Whats next, he calls Gill's harpoon a Pencil?"

Cynder replied, "A Harpencil? Who ever heard of that?"

Spyro spoke, "If all these crazy misguided names from the cooky Seagull are done. Some of us will have to go there and meet up with those three."

The Princesses/Portal Masters thought this over and Luna decided, "The flying Skylanders could provide air recon while our huge friend Thumpback meets up with them."

Celestia concluded, "We need to make sure Thumpback appears right there."

Spyro said, "Giant first." Thumpback stepped onto the Portal of Power and appeared right at the meeting place where Gill, Wham and Zap are.

Back on Earth, Thumpback appeared near Scuttle's rock which nearly made the bird jump. Gill Grunt spoke, "Thumpback, Man its good to see you again."

The Giant said, "Seeing you guys all right is music to my ears."

Ariel realized, "Music!"

The four Skylanders spoke, "Say what?"

The Mermaid finished, "The Concert, Oh my gosh, my Father's going to kill me!"

Flounder spoke in shock, "The Concert was today!"

Gill remembered, "Wait a minute, You're the missing diva."

The Mermaid took off, not after waving bye to Scuttle. With her Skylander friends following behind, they took off for Atlantica. Thumpback had a feeling in his anchor that they were being watched when he saw two pairs of glowing yellow eyes underneath a rock.
