One day in the Cul-De-Sac, the Eds were preparing for their latest scam. Eddy cooked up a scam that involved building a giant rollercoaster. 

Eddy: Is the EdCoaster ready, Double D!

Edd: The EdCoaster is nearly finished, Eddy! I just need to run some....

Eddy: Aw let's test it out now! ALRIGHT, ED! GIVE THE EDCOASTER A WHIRL!

On the top of the flimsily made rollercoaster, Ed prepares to test it out. 

Ed: GEROMINO!

Ed then jumps into the EdCoaster instead of using the shopping cart. Ed bulldozes through the rollercoaster, eventually destroying it. As EdCoaster was reduced to rubble, Ed emerges from the rubble with a goofy smile on his face. 

Ed: EdCaster fun, Eddy! Ed is okay!

Eddy groans in anger as he turns to see the other Cul-De-Sac kids laughing at the destruction of EdCoaster. 

Edd: Hhm....back to the drawing board I guess. 

Eddy: Aw forget it, Sockhead! This stupid Scam was gonna fail anyway. I'm bored. Wanna watch some TV at my place. 

Ed: Oh oh! I have an idea! Let's play Space Outlaws!

Eddy: That...actually sounds fun. 

Edd: I can't help but agree! Though can it play it in a more...sanitary place? 

Ed/Eddy: TO THE JUNKYARD!

Edd: Oh dear....

 With that, the Eds began making their way to the Junkyard to play Space Outlaws. Meanwhile near the Junkyard, a spaceship crashes. As the spaceship crashes into the Junkyard, there is a moment of silence. The silence is broken by the sound of breaking glass as a Xenomorph exits the ship. Inside the ship was the mutilated corpses of the ship's crew. The Xenomorph inspects it's new surroundings as it let's out an ear piercing roar. Meanwhile on the other side of the Junkyard, the Eds had put on their Space Outlaws Costumes begun playing Space Outlaws. They were sitting inside a broken down van, sitting on top of a garbage heap.

Ed: And so the brave Space Outlaws find themselves marooned on the robot planet. 

As Ed monologues, Edd begins tinkering with the van's radio. 

Edd: Come in, Earth. Come in, Earth. Come in Earth repeat come in Earth! Oh dear! I'm getting no response! We're stranded! 

Eddy: Aw man! Well at least our "ship" has this comfy waterbed! 

Ed: By now, the evil robots that roam the planet will have no doubt heard the sound of our spaceship crashing! They're on their way here to vaporize us!

Eddy: Sure, Lumpy....

Eddy then kicks the horn on the car. The horn then loudly plays La Cucaracha. Outside the van, the Xenomorph hears the sound of the radio. It didn't take long before for the Xenomorph to follow the sound of the horn back to the van where the Eds were in. Back in the van, Eddy was chilling in the waterbed while Edd continued to tinker with the radio which plays only static. 

Edd: This is not good, Ed! I'm getting nothing on the radio! 

As Edd says this the sound of something landing on the top of the van scares the Eds. Ed falls back on the waterbed, causing Eddy to get launched into the van ceiling. Outside, the Xenomorph was scaling the van before Eddy's shape was formed on the top of the van. Inside the van, Edd pulls Eddy down. 

Eddy: Why I oughta....

Ed: The evil robots have found us! Mighty Space Outlaws! The time has come to seek freedom!

Without hesitation, the Eds rushed out of the van to fight the robots, but found nothing, not noticing the jet black alien creature on top of the van. The Xenomorph quickly spots the Eds. The Xenomorph leans in and prepares to lunge at the Eds to kill them. But as the Xenomorph was getting into position, the Xenomorph's movements caused the van to dislodge from the trash pile. The van then begins falling from the trash pile, narrowly missing the Eds before crashing into a separate trash pile. The Xenomorph was buried in the trash pile while the Eds grouped up.

Ed: The alien robots have heard our position! We must move forward! There's not much time, before the cold robot planet nights squeeze the life out of us.

Edd then pulls out a pair of binoculars and surveys the area. 

Edd: Yes! I can see way in the distance! Look! Out in the distance!

Edd then points to a make believe rocket in the distance. 

Eddy: Well what are we waiting for? Get me out of here!

Ed: Do not waylay yourself, Eddy. For I will guardeth the lead. We must hurry, friends! TO SHELTER! 

As Ed takes point, Edd readies his make believe laser gun. 

Edd: Come along, Eddy! The enemy is closing in!

Eddy: The sooner we find that space rocket, the sooner we can blast off out of here! 

As the Eds begin running, the Xenomorph digs it's way out of the trash pile. Once it does so, the Xenomorph shakes the garbage off of it. The Xenomorph then climbs up the trash pile to locate it's prey. Once it reaches the top of the trash pile, the Xenomorph quickly picks up the scents of the Eds. With that, the Xenomorph begins stalking the Eds, waiting for the right time to kill it's prey. But what the Xenomorph didn't realize was that stalking and killing the Eds was going to be easier said than done. As for the Eds, they didn't realize that while they played their game, they were being stalked an hunted by one of the deadliest creatures in the entire Galaxy.
