As the ship left the Deserted Island, Aggie and the I teams met up at the deck again.

"So, how's the island?" Aggie asked her friends.

"We're having a great time, Aggie." Fluttershy replied.

"Yeah. Nothing's gonna ruined our vacation trip, except protecting Drac, of course." Applejack said.

Suddenly, the elements around their necks started to glow.

"Hey, our elements shined." Kessie said.

"What does this mean?" Soarin asked.

"Does this mean we have a mission? Fixing a friendship problem?" Prenda guessed.

"AGATHA!"

A furious Lydia rushed towards her with her elements glowing

"What is this? Why is it glowing… ON MY VACATION?!"

"Aggie!" Mavis approached her, "It's glowing! What does it mean?"

Then, Vlad came too, "Aggie! My element's glowing!"

"I think all of our elements are glowing." Aggie said, "It's like there's a friendship problem."

"I DON'T HAVE TIME FOR FRIENDSHIP PROBLEMS!" yelled Lydia, then laid a finger on her face, "You better figure out what causes this glowing, because I don't want my vacation to be ruined!" She stormed away.

Mavis agreed with her aunt, "Sorry, Aggie, but Aunt Lydia is right. This is a family vacation. We shouldn't work like this."

"Don't worry everyone! I'll figure this thing out. So, you can go back to your relaxing… thing." Aggie said as Mavis and Vlad walked out of the deck.

"So, what is it?" Buttercup asked.

"For me, I think the friendship problem is Dracula is in trouble when Ericka's around," Aggie explained, "And our solution is to protect him at all cost."

"Uh, I don't think that's…" Smurfette tried to correct her, but she was cut off.

"Come on, we have a friendship problem to solve." Aggie rushed off the deck.

The I teams just glanced at each other, shrugged, and rolled their eyes as they followed Aggie.

At the foggy place of the ocean, the monsters went out of their staterooms, when there was an announcement

"Everyone, please assemble on the forward deck. We are arriving to our final destination: from the depths of creation, the might city has risen once again. Home to the greatest monster civilization the world has ever known, surpassing Athens and Rome in art, culture, and sophistication. I give you the legendary lost city of Atlantis."

As they approached, giant tentacles surrounded the boat and startled everyone.

"Whoa! It's a giant kraken!" Kelsey yelled in fear.

The I teams were ready to fight. Rico regurgitated a bazooka, ready to shoot. The Powerpuff girls were ready to fly to attack the mysterious giant figure. The 6th Main group/Angry Birds placed their slingshot on the deck, ready to launch themselves. The Combo Niños transformed into their animal forms. Luke took out his lightsaber, and Han took out his blaster. Twilight ignited her horn, and Rainbow Dash and her family fluttered a little high, ready to attack. The Kids Next Door took out their weapons, aiming for that giant figure. Judy and Nick took out their guns, despite of going on vacation they always brought their weapons. Mater took out his guns from his side, Finn took out his pistol, and Holley took out her tasers from her tires. Skipper Riley already had bullets in his wings. Danger Mouse was ready to fight bare-handed. The smurfs readied their bows and foam-arrows, and wooden spears. Lastly, Aggie readied her wandstaff, ready to recite any spell she got.

It was the Kraken, a legendary sea monster and lounge singer. And it began to sing:

There's a place, you gotta be
A thousand leagues beneath, the sea
And it's waitin' over here, for you and me

When Aggie and the team realized the kraken wasn't going to attack, they lowered their weapons and calmed themselves.

With a sweep of his hand, the fish man directed everyone to look out as Atlantis came into view.

Atlantis was like Las Vegas for monsters. It was glittery with bright lights.

Gonna take you for a ride, but first you gotta come inside
Get ready for, the party's on tonight!

When the ship docked, the monsters' oath to the Atlantis casino was lit with spotlights and lined with giant statues. Laser light shows turned waterfalls rainbow colors, and everything sparkled. The monsters approached a casino that looked like a giant aquarium, with fishes swimming through the walls, ceiling, and floor. There was even a roller coaster!

So, relax and just unwind
Leave your worries, all behind
And get ready for, the party is on tonight!

In the center was a giant statue of King Triton. The animatronic ruler greeted the monsters as they came in, saying, "Welcome to Atlantis!"

The monsters quickly settled in and started gambling.

Kelsey went to a row of slot machines and used all of her tentacles to pull five levers at once… and hit the jackpot on the first try.

So get ready, it's party time
It's party time!

Aggie wasn't so comfortable with the place. Casino and gambling weren't exactly her thing. In fact, she never taught her team for this.

"Ugh, gambling. I hate gambling. Even the casino!" Aggie groaned in disgust.

"No offense, aggie, but Xibalba and I loved to play pokers. Especially back in the days." La Muerte said, "I saw a table of it over there."

"If you want us too." Xibalba added.

Aggie rolled her eyes, "All it matters to me is my friends to be happy, so… go ahead." She swept her hand as the goddess teleported, leaving a trail of golden flower petals, and the dark god transported by turning into a gooey puddle of black tar. They left a trail of breeze on her face. "Ugh. I better check on Vlad if he's…" When she found Vlad, he was gambling with the other monsters as well, "You too, Vlad?"

"Come on, kid. It's just once in a lifetime." Vlad rubbed Aggie's hair, and focused back in the game.

The white vampire rolled her eyes and shrugged. She just let her friend do what he wanted to do. Then, she walked towards her friends again, "Well, Vlad is out. What else you guys wanna do?"

"Honestly, Aggie. We've been in Las Vegas and in a casino before so…" Bugs Bunny tried confess something, "We really like to play the games here so…"

Aggie rolled her eyes and waved her hand, letting the 12.1st Main group to gamble. The group rushed in to play with the other monsters. "Anyone else?!" she asked the rest of the I teams.

"I heard there's a rollercoaster and other ride here." Ferb said.

"Yeah. Let's go there!" Baby Twaty exclaimed.

The most of the I teams rushed out of the casino to try on the ride here in Atlantis.

"We'll just watch the fishes, shall we?" Rida suggested as the 1st Main group and the 4th Back-up group left to the aquarium, leaving Aggie behind.

The only team member left was her husband.

Aggie noticed him, "Why can't you join with the others?"

"Red smiled in respond, "The main reason I came to this vacation… is you. I want to spend some time with you… as always."

Aggie was so touch with her eyes turned to puppy eyes and smiled. Then, she spotted Drac moving quickly through the main casino and noticed him following Ericka.

"What's wrong?" Her husband asked.

"Oh, I, uh…" She didn't want to answer that she saw Drac following Ericka.

Red was just being sarcastic about questioning her. He saw Drac too. "Hey, whatever it is, you should go."

"What?!" Aggie was surprised of what Red said, "But, what about you?"

"Well, uh… I'll join Johnny over there, watching the fishes." Red pointed Johnny outside the casino, taking in the sights.

"Are you sure about that?" Aggie asked.

Red kissed her on the cheek, "Yes, so go. Good luck." He left to join Johnny to look around.

When her husband left, Aggie turned to find Drac. Then, she was joined by Mavis.

"Did you see dad going that way?" Mavis asked.

"Yep. Let's follow him." Aggie said.

The two vampires followed Drac to that forbidden room.

Mavis took in her bat form and Aggie stayed in her human/vampire form and followed Drac and Ericka. The two realized they lost sight them, until Aggie heard sounds from a stone face.

"Mavis, over here." She called her.

Mavis laid her ear on the face, and tired to open it, but she can't. Then, she crawled through the opening in the mouth. Aggie can't follow Mavis in that way. Even if she transforms into a bat, her belly is too big because of her pregnancy. Aggie tried to figure out of how to open this face. She turned the eyes, like they were door knobs, and the face opened in half. She went inside and followed Mavis.

Mavis and Aggie were startled when they were encountered by a black rat, who tried to scare them. They deadpanned when they realized the rat was trying to scare them. Mavis punched the bat, and Aggie turned it into a ball with her wandstaff and threw it on the wall as it bounced all over the place like a ball.

It took few minutes to track down Drac and Ericka again. Mavis and Aggie couldn't find them as they kept searching for them. Finally, they found them together, much to their horror.

"Dad?!" Mavis yelled.

Drac?!" Aggie gasped.

The first thing they saw was Drac was still a pincushion with spikes, arrows, and an axe on his head, which Ericka was trying to pull it out from him, but Mavis and Aggie thought Ericka was trying to kill him with the axe.

"Mavis? Agafya?" Drac asked as Ericka pulled the axe from his head.

"What are you doing to my father?" Mavis shrieked angrily at Ericka.

Mavis and Aggie, with her wandstaff, levitated Ericka up into the air and left her dangling.

"Mavis! Aggie! Stop! Put her down!" Drac told them

Both girls refused as they kept dangling Ericka in the air.

"No way, she's trying to hurt you! Come on, Drac, why can't you see that?" Aggie asked.

"Because I… because…" Drac realized he can't keep a secret from her own daughter and friend anymore as he confessed, "Because I zinged."

Mavis and Aggie were so stunned, they dropped Ericka. "What?"

"I zinged… with Ericka." Drac answered.

"No, that can't be true. In your case, you only zing once," Aggie insisted.

"That's what I thought too." Drac shrugged.

"Zing? What's a zing?" Ericka asked.

"Uh, well, it's a thing for monsters," Drac explained. "It's kind like our love at first sight."

This was way too much for Ericka. She began to feel conflicted, even guilty.

"What? No. No, no, no, no, you don't even know me," she protested.

"Well, not yet, but we're just—"

Ericka interrupted. "No, no, you don't understand. I can't be with you. I could never be with someone like you. I could never be with… a monster!" She turned and walked away, carrying the device.

Drac was heartbroken. Mavis and Aggie went up to him.

"Dad, we're so sorry. We just…" Mavis apologized.

Drac sighed. "It doesn't matter. You heard what she said." He walked away from Mavis and Aggie, wearing his cape that he left behind earlier and leaving the two girls alone.

"But a zing never lies," Mavis muttered, sharing the same glance to Aggie, who agreed of what she just said.
