Mike was invited by Otto and Reggie to come on a field trip to the Nicktoons Museum of History. Raymundo had encouraged them to go to get a decent education, and of course, Sam didn't mind that, though Twister and Otto looked like they would rather be anywhere else other than here. Little did they know that this would be the start of their newest adventure together. The SpongeBob gang was there themselves, though for the first while, minus SpongeBob and Patrick.
"Ooh...Uh... Beautiful day for standing outside a museum doin' nuthin'." Mr. Krabs smiled innocently.
"Whatever you say. "The security guard shrugged to him.
Mike soon walked over with the Rocket Power gang. "Mr. Krabs, is that you?" she then asked as she stood beside Otto while Reggie was with Arnold and Sam and Twister were by themselves.
"Uh, yeah, I'm doin' me new job while the Krusty Krab is closed," Mr. Krabs smiled innocently. "Welcome to the museum! That'll be three dollars."
"I thought it was Tuesday?" Twister replied. "The museum is always free on Tuesdays."
"As much as it kills me to say it, Twister is right." Otto replied.
"I was right about something? Awesome!" Twister cheered. "One in a row, it's a new record!"
"No, no, no, today's Monday," Mr. Krabs replied before he showed his undershirt. "Otherwise I wouldn't be wearing this 'I Hate Mondays' shirt."
"Oh, boy, he has a point there, guys." Twister replied.
"It's Tuesday and I know it is!" Mike narrowed his eyes. "Raymundo gave us money for a movie or the arcade after if we promised him we'd go to the museum today since Otto's been sleeping in class lately."
"I can't believe he told you that..." Twister groaned. "What a date this is turning out to be for Otto!"
"It's not a date!" Mike and Otto defended while blushing.
"Mr. Krabs, stop lying and conning people out of their money," Arnold scolded the cheapskate crab. "We're going into the museum for free and we're not gonna let you stop us unless you want us to have a word with those guys." he then gestured to the police officers who seemed to be visiting the museum as well.
Mr. Krabs looked nervous and soon went into the museum without another word which allowed the group to go inside.
"Look on the bright side, guys," Arnold told his friends. "At least the Krusty Krab isn't open today and Mr. Krabs won't be slaving away his employees today."
"I really hope they get rid of him soon," Reggie replied. "I'm starting to feel sorry for Squidward."
"Yeah, I can really relate to him." Sam agreed.
They soon came into the museum and Squidward was there, not surprisingly, checking out the art section of the museum.
"Neptune's ascension," Squidward smiled. "The only surviving painting from the great lost city of Atlantis. This is just what the doctor ordered, Squiddy."
"Someone's in a good mood." Mike commented.
'Ah, Michelene, so good to see you visiting good old Nicktropolis," Squidward smiled to the tomboy in pigtails. "Isn't it great to be alive?"
"It's Mike, easy with that Michelene stuff, but I'll go easy on you since you're in such a good mood." Mike replied.
"What brings you children to the museum?" Squidward asked.
"Raymundo wants Otto to make up for sleeping in class and getting away with it." Reggie smirked to her younger brother.
"Reg!" Otto glared at his older sister.
"Otto." Reggie playfully retorted.
"Well, you're welcome to join me," Squidward invited. "Spending your day studying the Atlantean masters."
"Uh... Maybe later, we're checking out the museum first." Twister replied dumbly.
Squidward rolled his eyes at Twister's slowness. "Anyway, the best of all is no Sponge-"
"Ooh, there's SpongeBob." Sam noticed.
"Hi, SpongeBob!" Mike smiled and waved.
"Hi, Mike!" SpongeBob replied before he and Patrick ran Squidward over with something golden.
"Oh, would you two watch where you're-" Squidward glared at his neighbors before gasping. "What is that?" he then asked once he saw the golden thing. "What are you doing with the Amulet of Antlantis?"
"That's one big amulet..." Arnold commented about the size.
"We were just-" SpongeBob tried to explain to Squidward.
"You're going to steal it?" Squidward glared in accusation.
"What?! SpongeBob would never steal!" Mike told the celphapod. "Otto, maybe, but not SpongeBob."
"Hey, I thought you were on my side!" Otto glared.
"Oops, sorry, Otto." Mike giggled innocently to her current boyfriend.
Otto rolled his eyes and grumbled while folding his arms.
"Mike's right, Squidward," SpongeBob agreed with the tomboy. "We'd never-"
"This is a new low, even for you two!" Squidward glared at SpongeBob and Patrick before taking the amulet to put it on the display only to see the other half of the amulet was broken. "Lucky for you, I was here today. Stealing artifacts could land you in the stony lonesoooooome?! You boobs found the missing half to the Atlantean amulet?"
"What's an Atlantean omelet?" Twister asked.
"Amulet, not omelet!" Squidward glared at him. "It's the key to untold riches!"
Mr. Krabs suddenly rushed over, shoving down the others violently. "Did somebody say untold riches?" he then asked greedily.
"Yes, Eugene," Squidward smiled to his boss. "The streets are lined with gold, and the street lamps are made with diamonds."
"Diamond light bulbs?!" Mr. Krabs asked. "I wonder what they make the money out of."
Otto snickered to his friends. "Mr. Krabs's first name is Eugene."
The others then laughed at that, but Arnold just shrugged.
"I don't get it." Twister whispered to Arnold.
"So, Squidward, what more can you tell us about Atlantis?" Sam asked out of interest.
"For reasons unknown, this great city disappeared one day, but no ruins were ever found," Squidward educated as he showed the mural of many inventions brought to them from the people of Atlantis. "All the inventions that you take for granted, were given to us by the Atlanteans. Their advances in art, financial wealth and weaponry were eons ahead of their time!"
"Why is there a bubble painted on the mural?" Reggie wondered.
"I believe that's the legendary oldest living bubble." Arnold replied.
"Indeed." Squidward nodded to him.
"The oldest living bubble alive!" SpongeBob gasped and jumped onto his best friend's back. "Behold, Patrick: The oldest living bubble!"
"This is the most beautiful bubble I've ever seen." Patrick looked amazed.
"Me too." Twister agreed in equal amazement.
"That's just a painting, you quarter-wits!" Squidward snapped before whispering to Mr. Krabs. "Quarter-wits. Ha, it's less than half," he then spoke up aloud again. "The real bubble lives in Atlantis, some dumb old bubble pales in comparison to the arts-"
"Money!" Mr. Krabs added.
"Oh, great, another Eddy..." Mike rolled her eyes.
"And science, don't forget science," Sandy suddenly appeared while adding in to what Squidward and Mr. Krabs were talking about. "What's all the hubbub, guys?" She then asked the group.
"These two Chowder Brains found the missing half to the amulet of Atlantis~" Squidward smirked as he pinched SpongeBob's cheek.
"The Amulet of Atlantis?!" Sandy gasped in awestruck. "Legend says, that when the two halves are joined, the path to Atlantis is opened!"
"Aw, man, this, I gotta see!" Mike beamed as she took the other half from Squidward. "Move over, Squidward, lemme handle this... I heard all about the legend from the 1910's in History Class about that guy, Milo Thatch." she then came to the display and put the two halves together so they could go to Atlantis.
A bright light soon activated after the two halves were joined just like in the legend. Twister, Sam, Otto, Reggie, Arnold, SpongeBob, and Patrick cheered to this and praised Mike since she had done it for them. Suddenly, a van dropped from the ceiling.
"The magical path to Atlantis is a van?" Squidward asked.
"Nice hot rod flames," Otto smirked. "I should ask Dad to let me drive this thing when I turn sixteen."
"Right after me!" SpongeBob chuckled.
"What's it doing?" Patrick asked about the amulet.
"Looks like it's attaching itself to the van." Sam guessed based on what he could see.
This was going to be the start of a brand new adventure for Mike and her friends.
