SpongeBob, Patrick and Squidward had returned to the cave they had taken a shortcut through, though this time they went down the path Sandy had gone down. Upon arriving SpongeBob began to search the cave for any sign of Sandy. Patrick did the same while Squidward did it in a less reckless manner.

SpongeBob: "Everybody get looking!"-SpongeBob panicked-"Sandy has to be around here somewhere."

SpongeBob and Patrick continued to panic and look around while Squidward just rolled his eyes and walked away, only to step on something. He looked down and saw it was the head of a fodder and looked to find many other destroyed robot parts.

Squidward: "You two might want to see this."-said Squidward, confused

SpongeBob: "It looks like Sandy got into a fight."-said SpongeBob, confused-"But where is she now?"

Patrick took a few steps forward before a loud, spring-like sound was heard in the background. They all looked to see a small cannon-like device sitting in the wall of the room. Squidward bends down and looks at the device in question.

Squidward: "I know what this is, I set one up for you two."-said Squidward, skeptically-"It's a booby trapped, net launcher. Looks like it only had one net though."

Patrick: "That must be what was used to catch Sandy."-said Patrick, proudly-"But where is she now?"

The group then walked back out of the cave with the net-launcher in hand. Suddenly a bright flash of light appeared and suddenly the chariot of King Neptune appeared before them.

King Neptune: "SpongeBob I'm so glad to have found you."-said Neptune, panicked-"I am in desperate need of your help!"

SpongeBob: "What's wrong, your highness?"-asked SpongeBob, confused

King Neptune: "Something large, dangerous and hideous has attacked my castle."-King Neptune, explained-"I was able to send it to the Posei-Dome but I'm afraid it's havoc won't end without a fight. So I need the three of you to fight it."

Squidward: "You can forget it!"-Squidward denied-"We are already on a very important miss-"

Before Squidward could finish King Neptune raised his trident to the sky and they all vanished in a flash of light.

Squidward: "..ion."

SpongeBob, Patrick and Squidward then appeared in a massive boxy-ring like area. They were surrounded by various patrons who held up signs reading things like 'Go Sponge Go!" and "Pat's got this". King Neptune appeared in the arena and held up his microphone.

King Neptune: "Yes hello and welcome to the Posei-Dome!"-Neptune announced-"Tonight this is sure to be a battle for the ages!"

As he announced this the crowd all cheered in a chorus of applause. Squidward then crossed his arms and turned to face the corner of the ring.

Squidward: "This is stupid! Having to risk my neck for the king with you two morons."-Squidward complained-"I can't do this! I'm out."

SpongeBob: "No wait, Squidward. We promised we stop this whole crisis, so this is one of the things zero have to do."-SpongeBob pleaded-"Plus, just think of the fans."

At the word "fans" Squidward looked and saw the cheering crowd before him. Suddenly thinking of becoming famous Squidward lost all intention of leaving.

Squidward: "Alright, let's do this!"

Suddenly a spotlight appeared on the distance and revealed the commentators: King Neptune's wife, Queen Amphitrite and their children Triton and Mindy. Suddenly Patrick once again showed his infatuation towards Mindy.

Patrick: "She's pretty, SpongeBob."-said Patrick, dazed

Suddenly Squidward slapped Patrick on the back of the head, snapping him out of the trans.

Squidward: "Patrick, stay focused!"-said Squidward, annoyed-"We've got a fight to win."

Triton: "In this corner we have: a small square dude!"-Triton loudly announced-"And a star and octopus who might have gotten me out of a cage last year or whatever."

Mindy gave an annoyed glance at her brother before turning to the microphone.

Mindy: "And this corner we have: a giant robot shaped like a squirrel!"

As she said "squirrel" SpongeBob was instantly shocked by this. They heard loud thunderous footsteps as a silhouette figure from behind the audience came running down through the the crowd, walking over the audience. Fortunately no one was hurt too seriously. The massive figure then jumped and landed in the arena with a loud bang. SpongeBob looked up in terror, the opponent was a massive robot that resembled Sandy.

Mindy: "This robot better watch out."-Mindy interjected-"It's up against the one sponge who was able to beat daddy in a cook off."

King Neptune: "Yes thanks you for bringing that up, honey."-said Neptune, embarrassed-"Now let the fight begin!"

Patrick and Squidward stood behind the ropes while SpongeBob stepped forward first. He was nervous but then reached inside his head and got another bottle of bubble soap.

SpongeBob: "Look, Sandy, we don't have to fight."-SpongeBob offered-"You've gotta be there somewhere, Sandy."

Robo-Sandy: "I like you SpongeBob, why we could be tighter than bark on a tree."

SpongeBob initially believed his talk worked but he quickly met with a hard karate chop.

Triton: "Oh and it looks like just won't be enough for the square dude."-Triton announced-"He better pick himself up."

SpongeBob then got up before he was chopped once again. He began running around as the robotic Sandy chased him and tried karate chopping him. The robot then karate chopped but SpongeBob was able to block this one with a bubble shield.

Squidward: "Come on, SpongeBob, you won't win this running away!"-said Squidward, annoyed-"Fight the robot back!"

Per Squidward's request SpongeBob tried to do a bubble spin to the robot's leg. This however did no damage and the robotic Sandy looked down at him mockingly.

Robo-Sandy: "Oh I was just goin' since y'all are oh so delicate."

The robot then raised her hand again to karate chop and SpongeBob runs out of the way. The robot jumped into the air and landed on its butt while Sending SpongeBob up into the air. In an act of desperation, SpongeBob blew a random bubble that turned out to be the bubble bounce. Once the bubble feet made contact with the robot's head, however, the robot suddenly had sparks flying while falling backwards and damaging part of the ring.

Mindy: "Oh and SpongeBob finally lands a hit."

Patrick: "All right, SpongeBob!"-Patrick cheered

Squidward: "You found it's weakness."-said Squidward, seriously-"Use that to your advantage!"

SpongeBob then got out his bubble soap and turned to the robot with a smirk. The robot then stood back up and got into a fighting stance.

Robo-Sandy: "Oh well, your game:your rules."

The robot then attempted to perform a karate kick that SpongeBob ran out of the way of. SpongeBob spun his wand under his feet and send a bubble rolling like a bowling ball into the robot's leg. Robo-Sandy then chased after him and tried to attack while SpongeBob either dodged or blocked with a bubble shield. The robot once again jumped into the air to try and land on SpongeBob. As he flew into the air once more SpongeBob blew his bubble feet and once again made contact with its head. The robot accidentally karate chopped the scoreboard and made it fall down to the back of the ring.

Triton: "And it looks like the sponge bro is takin' a rad turn!"

Suddenly the robot got back up and stared down at the three in the ring. It's read eyes glowed brighter, indicating anger.

Robo-Sandy: "Which one of you is the real Dirty Dan?"

SpongeBob back away nervously but did not expect what came next.

Patrick: "Hey Sandy!"-said Patrick, prepared-"I'm Dirty Dan."

SpongeBob: "Patrick, what are you..."

Patrick held up his hand in a high-five position, indicating a switch. SpongeBob smirked and high-fives Patrick while getting behind the ropes himself. Patrick then jumped over the ropes and into the ring to face the robot.

Patrick: "Mindy, this one's for you."-said Patrick, flirtatiously

Robo-Sandy: "I'm 'onna get you, Dirty Dan!"

The robot then readies to karate chop Patrick. Once the robot brings down a hand Patrick catches it and holds it in place. Using his powerful strength Patrick then threw the robot back onto it's side.

Mindy: "Ooh and looks like this star's got strength!"

SpongeBob: "Whoo Patrick!"

Patrick then turned back and saw the robot Sandy stand back up.

Robo-Sandy: "I have an idea how we can kick things up a notch!"

Patrick: "Why do I not like the sound of that?"-asked Patrick, worriedly

The robot then pulled back the ropes and launched towards Patrick. It's limbs then sprawled out in long spirals and it moved towards Patrick. The clotheslines then made contact with Patrick and caused him to spin around and be launched into the air. Patrick then hit the ground with a loud thud.

Mindy: "Oh and Patrick's getting hit with the clothes line".

Squidward: "Get up, Patrick!"-Sqyidward urged-"You can do this!"

Patrick then got back up and held up his fists to the massive robot. The robot once again did a clothesline but this time Patrick jumped over it. Patrick then pounded the ground and caused the robot to loose its head. The body then went crazy and the limbs began destroying the walls of the Posei-Dome. Patrick grabbed the head and using his strength he through it into the scoreboard, causing a malfunction in the robot.

Mindy: "And it looks like Patrick got the upper hand."

Triton: "Save some for me, sis."-said Triton, annoyed-"Wuit hoggin' it all!"

Patrick walks back over to the side of the ring where SpongeBob and Squidward wait.

SpongeBob: "That was amazing, Patrick."-said SpongeBob, excited

Squidward: "Yeah, real amazing."-said Squidward, uninterested-"Here tag me in!"

Patrick hi-fived Squidward and climbed back behind the ropes. Squidward then got into the ring with his clarinet ready. The robot tried to karate chop but Squidward quickly ran out of the way. Squidward then began playing his clarinet but it did next to nothing. The robot then jumped back and once again did a clothes line move, which Squidward narrowly dodged.

Triton: "Oh and it looks like that music just won't cut it!"-said Triton, smirking

Mindy: "Oh that's just pretty."-said Mindy, sarcastically

Squidward then ran as the robot on nice again got ready with a karate kick. The robot then walked to a nearby pillar and stared right at Squidward.

Robo-Sandy: "Too bad you forgot yer umbrella."

The robot then kicked the pillar and caused a large chunk of the ceiling to be destroyed. Squidward then became scared and ink squirted onto the robot's helmet while he narrowly made it out of the way. The robot then gave a karate chop but due to its inability to see it destroyed a part of the bleachers. Squidward saw this and smirked with an idea.

Squidward: "Hey robot."-said Squidward, mockingly-"I'm over here!"

The robot came towards him and he played his clarinet that caused the robot to stumble. The robotic Sandy accidentally karate chopped part of the wall while Squidward got to the other side of the ring.

Squidward: "Nope I'm over here!"

The robot then tried to do a clothesline but it went right into the ropes and it's limbs spun around while destroying parts of the walls and weakening part of the ceiling.

Mindy: "It would appear Squidward is misleading the robot."-Mindy commentated-"But what is his big plan?"

As the robot angrily spun around and destroy much of the walls, Squidward looked to the ceiling with a smirk. He played his clarinet upward and many parts the ceiling came crashing down on the robot, causing it to malfunction yet again.

Queen Amphitrite: "Can you please be more careful?"-asked Amphitrite, annoyed-"We're barely still in the range of our insurance covers."

Squidward walks away from the robot and over to the side of the ring. Suddenly the robot once again got back out of the rubble that covered it. The robotic Sandy then took off its glass helmet and smashed it on the ground.

Robo-Sandy: "And I don't need this helmet, neither!"

Squidward suddenly became nervous and walked back to the sides.

Squidward: "SpongeBob, how about you finish this fight?"-asked Squidward, nervously

Squidward then hi-fived SpongeBob and got back behind the ropes. SpongeBob took his bubble soap and jumped back into the ring.

Triton: "And the square dude it back!"

Mindy: "But what will he do?"

SpongeBob dipped his bubble wand into the soap and held it in front of his mouth. The robotic replica of Sandy then walked up and held up its hand for a chop. The robot had much missing plates and exposed wiring but still seemed determined to defeat him.

Robo-Sandy: "Okay, Pinhead Larry, it's your turn."

The robot brought down a karate chop that SpongeBob then blocked with a bubble shield. He runs around the robot as it tries to attack him. SpongeBob then blows bubbles that he then uses as bowling balls to hit around the robot's legs. He then jumps into the air and does a bubble-bounce directly onto the robot's face. The robot then recovered and stared right at him. As sparks flew from its head the robot seemed to be staring right at SpongeBob.

Robo-Sandy: "Now this is where the real accidents happen!"

The robot then pulled up a chunk of the floor and attempted to slam it onto SpongeBob. He then turns into a ball and rolls out of the way of the robot. As the robot threw the chunk of floor, SpongeBob jumped on top of it. He jumped off and the chunk hit the wall and destroyed that part of it. SpongeBob turns into a hang glider and flies up into the air. He turns back to normal and blows a bubble in the shape of a bomb that comes crashing down and exploding against the robot's face, just as he safely lands on his feet. The robot then begins going haywire before falling to pieces and landing on the ground with a loud crash. The crowd cheered and waved as the robot was defeated and SpongeBob emerged victorious.

Patrick: "Whoo SpongeBob!"-Patrick cheered-"We won!"

Patrick runs to SpongeBob and hugs him while spinning around. Squidward half heartedly nods and pats SpongeBob on the back. The royal family then joined them in the ring while King Neptune picked each of the trio up by the arm and lifted them into the air.

King Neptune: "We have our winners!"

SpongeBob waved to the crowd in excitement before he notice something move in the robot's remains. The metal panes were pushed out of the way and from under them appeared Sandy's familiar face.

SpongeBob: "Sandy!"

SpongeBob then pulls himself free of the king's grip and hugs Sandy. Patrick and Squidward then joined the two in the ring.

Sandy: "SpongeBob? Patrick? Squidward?"-asked Sandy, confused-"What in tarnation was goin' on?"

SpongeBob: "You were just inside a massive robot that looked like you that was trying to destroy us."-SpongeBob quickly explains-"Which really explains why the robot was only talking in things you've said before."

Squidward: "Well according to this, Sandy wasn't the pilot, she was the power supply."-said Squidward, taking a label-"My only question is who's been controlling the robot if you weren't."

Neptune then came and joined everyone while holding his trident once again.

King Neptune: "Congratulations on winning."-said Neptune, proudly-"For this you win: a ride home!"

King Neptune the used his magic to summon a bus from thin air.

Queen Amphitrite: "But that is not all."-Amphitrite interjected-"You have also won the people's respect."

Mindy: "And a gift card for six dollars and seventy five cents to Dean's little shop of dried fish flakes and flowers."

Triton: "Yeah I still say that's a pretty lame prize."-said Triton, unimpressed-"But I guess a sweet hot rod for a dude that don't have a license wouldn't make much sense."

Patrick: "Goodbye, Mindy."-said Patrick, infatuated

King Neptune then picked up Patrick by the tip of his head with an irritated expression. The king then threw Patrick into the bus and used his trident to pile everyone else in before it took off.

Mindy: "Uh isn't that the bus driver who was supposed to drive the bus?"

Everyone looks and sees a bus driver who was tied up and squirming in their direction.

King Neptune: "Of course it is, sweetie."-said King Neptune, confused-"Wait but if he's here, then..."

In the labs of the Chum Bucket the mysterious mastermind was looking at a computer screen. The screen shows an image of the robotic Sandy before it turns red and a "DESTROYED" label appears on it.

???: "They really think they've won?"-asked the mastermind, mockingly-"They may have vested phase one but they're in for a surprise."

A map leading to Rock Bottom then appears on the screen. The mastermind then evilly laughs to himself in a cocky manner.

On the bus ride Sandy rubbed her head in pain and annoyance. SpongeBob took noticed and turned to his friend.

SpongeBob: "Are you okay, Sandy?"-asked SpongeBob, concerned

Sandy: "When I was sedated, just before being put in that there robot, I spoke to the varmint behind all this."-said Sandy, groggily-"I couldn't seem him but I reckon this is worse than we darn thought."

Everyone else then notice Patrick chewing on a piece of metal that seemed to come from the robot they had just fought. Squidward then took the metal and noticed their was writing on it.

Squidward: "Project Robot Replacement: Phase One?"-Squidward read, confused-"What does that mean?"

Patrick: "I don't know?"-said Patrick, ignorantly-"But did anyone else notice s we're leaving Bikini Bottom?"

SpongeBob: "What?"

Patrick: "We passed the sign."-Patrick indicated-"See? You are now leaving Bikini Bottom."

SpongeBob was shocked but then noticed they were indeed leaving Bikini Bottom. He then looked forward and noticed that the driver was a fodder wearing a hat. He then freaked out from the revelation.

Author's Note: Okay so for this chapter I used inspiration from Superfloxes' Battle for Bikini Bottom fanfic, I just couldn't think of anything else really. So since this was inspiration, Superfloxes, you get the full credit for this chapter. Don't worry future ones will not be like this, except for the robot boss fight. Thank you.
