As the Amtrak Train came out of forest, the 3 campers are heading.

"i'm not a bird anymore!" said Sugarcoat.

"We must be arrived the forest!" exclaimed Sci-Twi.

"You right!" yelled Sunset.

"Sugarcoat, prepare to walk on the moon!" proclaimed Sci-Twi.

"Aye, aye, Captain!" replied Sugarcoat.

Sci-Twi carefully opened the door of the train. They popped their heads out and saw . . . Pinkie Pie's house and Rarity's house and Applejack's rock.

"Wow . . . the moon sure looks a lot like home," said Sunset.

"Good!" said Sci-Twi. "We won't feel homesick."

Sci-Twi carefully stepped out onto the sand. "This is one small step for a sponge, one giant leap for spongekind!"

Just then Spike, Sci-Twi's pet dog, came crawling by.

Sunset pointed. "Hey, look! It's Spike!"

"Meow," said Spike.

"Come here, Spike!" cried Sunset as he started to run toward him.

Sci-Twi grabbed Sunset. "Stop! Don't go near him!"

"Why not?" asked Sunset.

"This is all a trick!" warned Sci-Twi. "The aliens are projecting our memories onto the environment! They want us to think this is Cartenlot City, but it's realli; the moon. They're trying to confuse us!"

Sunset scratched his head. "You mean to say they've taken what we thought we think and made us think we thought our thoughts we've been thinking are thoughts we think we thought?"

Sci-Twi nodded. "I couldn't have said it better! But we're not going to fall for it!"

Sci-Twi aimed the moon rock harvester popgun at Spike. "You who are not Spike, but pretend to be Spike, prepare to be harvested!"

Sci-Twi pushed the button on the moon rock harvester. ZAP!

Suddenly Spike was wrapped up in a net.

Sci-Twi grinned. "Now what do you have to say for yourself, Mr. Alien?"

"Meow," said Spike.

"You got 'em, Sci-Twi! What a shot!" cried Sunset. "Boy, is Sandy gonna be proud!"

Sci-Twi turned pale. "Sandy! Oh, no! I forgot all about her! She's going to be really mad at us for stealing her rocket!"

Sci-Twi didn't know what to do. He couldn't stand the idea of Sandy being mad at him. He was trying to think of something he could say or do when Spike meowed again.

"That's it!" said Sci-Twi. "Sandy won't hate us when I bring her back a real live alien! Or two! Or three! Or four! Or more! She'll love me! Come, Sunset! Let the alien harvesting begin!"

Sci-Twi raced across the sand toward Pinkie Pie's house.

Sugarcoat followed and began to yell excitedly, "Oh, boy! Alien hunting! Alien hunting!"

"Quiet, Sugarcoat!" whispered Sci-Twi. "We can't let the aliens know we're on to them."

Sci-Twi then spoke loudly so anyone nearby could hear. "Oh, yeah! Alien Hunting. That was a great TV show! Amazing special effects!"

Sci-Twi motioned for Sunset and Sugarcoat to follow him to Squidward's front door. "Hey, guys!" he shouted. "Let's go visit our good old friend Pinkie Pie and see what he's up to!"

Sci-Twi knocked on the door.

No one answered.

They quietly pushed the door open and went inside.

"Make sure your alien harvester popgun is ready to go," whispered Sci-Twi as they walked into Pinkie Pie's bedroom.

Pinkie Pie was asleep in his bed. His four little bunny slippers were next to his bed on the floor.

"That is one ugly alien," said Sci-Twi.

"It's disgusting!" added Sunset.

Pinkie Pie was dreaming and talking in his sleep, "Uh... no... Grandma... don't take away my clarinet... I'll be a good girl."

The 3 Campers walked right up to Pinkie Pie's bed and looked down at him as he slept.

"It's even uglier up close," whispered Sci-Twi. "Let's begin the alien examination."

Sci-Twi pulled back Pinkie Pie's blanket. Pinkie Pie was wearing a nightshirt with little bears and ducks on it.

Sunset looked closer. "Look! There's something underneath the alien!"

Sci-Twi saw something red and rubbery under Squidward's body.

"I think I'm going to be sick!" said Sugarcoat.

Sci-Twi pulled it out. It was only Pinkie Pie's rubber hot-water bottle. He used it at night to keep himself warm.

But Sci-Twi thought it was something else. He held it up to 2 Campers. "Do you know what this is?" he asked.

"It's stinky!" replied Sunset.

"No," said Sci-Twi. "It's an egg sack!"

"It's a stinky egg sack," said Sugarcoat.

Sci-Twi continued. "This disgusting alien creature has laid an egg, and if I'm correct, it is filled with baby aliens!"

"Now I know I'm gonna be sick!" cried Sunset.

Sci-Twi held the hot-water bottle up to the lamp next to Pinkie Pie's bed. The light shone behind the hot-water bottle and showed the silhouette of Pinkie Pie's two hands.

"Twins!" cried Sci-Twi. "Horrible, disgusting, evil alien twins!"

Just then Pinkie Pie turned over and one of his hands landed on Sunset's face.

SPLAT!

"Help! Get this thing off of me!" screamed Sunset.

Sci-Twi quickly reached up to pull Pinkie Pie's tentacle off of Sunset's face.

It was stuck!

"Don't let the alien get me, Sci-Twi!" cried Sunset.

"I won't!" yelled Sci-Twi.

With all the noise and yelling, Pinkie Pie woke up. "Campers! What are you doing in my bedroom? Give me back my tentacle!" Pinkie Pie pulled his tentacle off Pinkie Pie's face.

"The evil, disgusting thing is awake!" cried Sci-Twi.

"Hey! Watch who you're calling evil and disgusting!" yelled Pinkie Pie.

"Let's capture the little phony!" said Sci-Twi.

"Get away from me!" yelled Pinkie Pie as he jumped out of his bed.

Pinkie Pie tried to run away, but Sugarcoat tackled him.

"Ouch!" cried Pinkie Pie.

"Hold him, Sugarcoat!" yelled Sci-Twi as he got his moon rock harvester ready and aimed it at Pinkie Pie.

"Sci-Twi!" cried a terrified Pinkie Pie. "What in the name of Neptune are you doing?"

"What any other patriotic Bikini Bottom citizen would do!" declared Sci-Twi.

ZAP!

Mr. Krabs, SpongeBob's boss, and owner of the Krusty Krab, was out taking his sea snake for a late-night walk.

Mr. Krabs was thinking of all the money he had made that day. Suddenly he heard a strange noise and saw 3 Campers coming out of Squidward's house. They were carrying a very mysterious-looking bag.

"Ahoy there, lads! Up a bit late to be playing pirate, aren't ya? Got yourselves a new mate?" asked Mr. Krabs with a laugh.

Sci-Twi nudged Campers. "It's another alien! Let's get him!"

They both pulled out their popguns and aimed them at Mr. Krabs.

Mr. Krabs was terrified. "No! Don't shoot me!"

Sci-Twi got him in his sights. "Ready,

aim—

ZAP!

And the next thing he knew, Mr. Krabs was caught in a net.

"SpongeBob!" yelled Mr. Krabs. "If you don't let me out of here, you'll never flip another Krabby Patty as long as you live!"

"Nice try, alien!" said Sci-Twi.

Meanwhile Sandy had landed on the forest. She looked and looked and looked, but there was no Sci-Twi and no train.

"Where did that knucklehead go?" she wondered. "He must've gone back to Bikini Bottom. I'd better get back there too."

She pushed the button on her car and back home.

Down in City, SpongeBob and Patrick went back to the rocket ship. They tossed the nets with Pinkie Pie and Mr. Krabs into the cargo hold with Spike.

"Ouch!" cried Pinkie Pie.

"Ow!" yelled Mr. Krabs.

"Meow," said Spike.

Sci-Twi stared at the three of them. "Look at them! Squirming around in there like a bunch of ugly, disgusting aliens!"

"They're gross!" said Sunset.

Sci-Twi closed the hatch. "It's a tough job, but someone has to do it! And that someone is us! We have a mission, Guys. It's time for an alien roundup!"
