Cindy, Libby, Sheen and alternated Jimmy entered a dimension that really wasn't much appealing. It gave them an eerie feeling all except for Jimmy who was too distracted by a yellow and pink spotted butterfly fluttering around his large, empty head.

"Pretty!" Jimmy happily accepted the butterfly's challenge and chased after it down the street.

"Jimmy no wait!" Cindy tried calling to him, but he was too focused on the race with the butterfly to listen.

"Well don't just stand there! After him!" Sheen took off after the dim-witted idiot down one of the filthy city's streets. Libby was about to follow her admirer's footsteps, but her best friend tugged on her arm and pulled her in her direction.

"Look!" Cindy pointed upwards. A neon green pod was flying at light speed across the pale yellowish blue sky out of the human's eye's view.

"The green pod has already hit here," she explained.

"But where is it going now?" Libby questioned.

"I'm not sure but c'mon, maybe Jimmy will lead us to whoever was hit," Cindy replied.

Cindy and Libby ran to keep up with Sheen and Jimmy. Cindy ran a bit faster than Libby, fast enough to get in the way of and oncoming figures. Their bodies slammed into one another, pushing them each into the ground.

"You jerk, watch we're you're going!" Cindy got up and wiped the dirt off her clothes. The person that shot her down was a pale boy about her age. He had jet black scythe- shaped hair, small brown eyes covered by clear glasses. He wore a long black trench coat, black pants, black boots and a blue t-shirt with a silver straight face in the center.

"Oh I'm so sorry," the young boy said sarcastically "but I actually care about saving all of mankind from an evil alien race!" He got up from where he had fallen. Libby, by this time, had caught up with Cindy.

"I gotta go, oh and if just happened to find a kid with green skin and no ears, come look me, he's evil. My name is Dib,"

"Ok?" Cindy wasn't exactly sure if this guy's giant head was in the correct place.

Dib nodded and ran in the direction he was originality going. Cindy watched as he ran away.

"Hey look, Sheen finally caught Jimmy," Libby pointed.

"Yeah the butterfly got squished on the wind shield of an oncoming car. It was kinda easy after that," Sheen walked towards the girls holding his loopy friend's shoulders.

"Butterfly go bye-bye!" Jimmy cried.

"Psst, is he gone?" a close by, unknown whisper voiced out.

"Who said that?" Cindy asked a little nervously. The three and Jimmy browsed around the city-full area for the mysterious voice.

"I did!" A green boy popped upside down in Cindy's face. He used four metal legs attached to a metal device on his back to hold himself in that position.

Cindy jumped at his surprised appearance and punched him into a nearby building in self-defense.

"I'm ok!" he called.

"Who are you!?" Cindy screamed angrily back at him.

The boy inserted the metal legs back into his back device. He dizzily walked back to the group and shook his head to bring himself back to normal.

"Whoa! His skin's green!" Sheen noticed.

"Yes, it's a skin condition. My name is Zim and I'm playing hide and seek with my best friend Dib!" Zim explained.

"We just saw Dib. He mentioned a green boy wanting to rule all mankind," Cindy informed. 'Wouldn't that be you?"

"Silly human, I don't want to rule Earth. I love Earth! It's the most perfect place in the universe!" Zim giggled cheerfully with a glowing face, creeping the others out.

"Do you guys want to play? I'm always looking for new friends to play with," Zim grinned waiting for an answer.

"Look, we're sorta busy right now and don't have any time for games," Cindy remarked.

"Wait Cindy, maybe he's got something to do with the green orb we saw," Libby suggested. "Zim, did you see a green orb thing flying around?" she asked.

"Now that you mention it," he began "I think it may have hit me because I strangely woke up near the playground at skool earier, I don't even remember falling asleep, but everyone was staring and whispering about me. Did I do something wrong? Was I not being a good friend? Did I hurt anyone on accident? No one spoke to me, so I ran off. Dib came to my house later and asked if I had anything to do with some kind of green orb. He seemed a little angry about it, but I know he was just concerned. That's why I started a game of hide and seek to make us feel better! He's still looking for me! Hehehe!"

"Y'know, you could have just simply told us that Dib said you got hit with the orb instead of rambling on about your whole life story!" Cindy yelled annoyed.

"It's always best to express your feelings to friends," Zim smiled again.

Both Cindy and Libby rolled their eyes.

"If this is his altered personality, I'm afraid to know what his real one is," Libby stated quietly.

"C'MON! We found who we were looking for! Can we go now? This place gives me the creeps!" Sheen was impatient. He was still holding on to Jimmy's shoulders.

"Ooh! Where are we going? Is it an adventure? Came I come? Please!?" Zim showed off puppy-dog eyes and held his hands together.

"Yes Zim, you have to come with us. We're dimension jumping," Libby answered.

"Yay!" Zim spun and jumped around in excitement. "Dib will never be able to find me! I'm so good at this game!"

"Oh, but how are we supposed to get back to Retroville?" Cindy questioned.

"Don't worry, I know a scientist who just happens to own a portal," Zim lead the others to Dib's house, skipping delightfully.
