Zim stared moodily at the warped piece of machinary before him, deep in thought. He had been trying to salvage some of the wreakage from GIR's last adventure in his labs, but for the past hour or so he'd just been glowering at the twisted blob of metal as if he blamed it for whatever was troubling him.

A distant explosion reverberated through the dim room, shaking Zim at least partially from his trance.

"Grah! That miserable worm-monkey! How dare he mock the incredible plans of ZIM?" he began pacing about the little room, waving his arms dramatically as he ranted.

"If there was any kind of a brain at all in that disturbingly large head, he would see the doom that awaits his miserable planet! But no, not the Dib-monkey! Why can't he just be dumb like the rest of his revolting species?" He fumed, kicking another discarded casualty of GIR.

He stormed to the elevator, switching from ranting to mocking Dib.

"I'm Dib! I spy on people, and wear stupid little glasses!"

He continued his mockery as the computer carried him to the house level, acting in full like an angry 5-year-old. Except where a 5-year-old would throw a tantrum, Zim blew things up or sent death-bots after people.

He was met with a blast of smoke as he stepped from the elevator, left from the explosion he hadn't noticed earlier. He coughed, waving his arms in an attempt to clear the thick air around him.

"GIR! What did you do?"

"Hi! I made skettios!" The ever-cheerful robot screeched, swinging down through the smoke from somewhere amongst the tangle of wires that made up the ceiling.

"How does making skettios blow a hole in the wall of the base?" More than a hole, an entire wall seemed to be missing. One thing the robot had going for him, he was a master of destruction.

GIR beamed up at Zim, shrugging mindlessly and putting forth all of his cuteness. Zim glared for a minute before succumbing to the adorableness of his side-kick.

"Whatever. Go…clean up the mess you made, or something," he sighed, making his way through the fog to where the couch ought to be. A large portion of it was still there, though half of what was left seemed to have just recently stopped burning. He stared at it skeptically before deciding it probably wasn't safe to sit on.

"Computer, repair the base. I'm going out until repairs are finished," he announced, quickly donning a disguise and ignoring the groaning of the computer as he marched through the new exit.

Once past the oppressive cloud of smoke looming over his house, he made up his mind to spy on Dib. After all, he needed to find out what purpose that picture would serve to set his paranoid mind at ease. Even if the humans did think the Dib was crazy, an Invader could never be too careful.

Dib was sleeping as peacefully as he ever did, tossing and turning in a dream and completely oblivious to the shadowy figure crouched on his windowsill.

Zim slid the window open, using his spider legs to move over and away from the bed. All caution and stealth became rather pointless when he tried to drop to the floor, missed his landing and crashed into a table.

Stacks of papers, books, a lamp, and some dishes crashed to the floor, many of the dishes breaking. The lamp bulb shattered and the lamp sent up a small mushroom cloud, catching some papers on fire. Zim leapt to stop out the fires, flailing and screeching like a rabid monkey.

Somehow, miraculously, Dib slept through it.

Once the chaos had subsided and everything was quiet again, Zim turned to a desk and slid open a drawer.

That woke Dib up.

"Wha- Zim? What are you doing here? Get out of my room!" He yipped, surprised and not fully awake.

"I come to spy, Dib-creature! And!" he paused dramatically, "…MAKE ME!"

He laughed maniacally, certain that Dib would have no counter for that, when he was rudely cut off by being whapped upside the head with a pillow. He glared venemously.

"This is WAR, human! WA-mmph!" An alien plushie smacked him in the mouth, successfully silencing the Invader.

Zim grabbed the pillow at his feet and, shrieking his Irken battle cry, he lunged at Dib.

Soon an all-out pillow war was being waged, only a few feathers from a fist fight. Zim's pillow burst, giving Dib the upper-hand, if only momentarily.

"Hah! Gotcha now, space boy!" He sneered, merrily bashing Zim with the pillow with considerable force. Zim tried to ward him off and defend himself, knocking into random furniture, the walls, and falling more than a few times.

Unfortunately, he fell one time too many.

The door slammed open, revealing a very angry, very pink Gaz decked out in her piggy pajamas. Both boys froze, staring towards the door as if it were a portal to hell or something much less pleasant than that. She took a menacing step foreword.

"Dib…some people are trying to sleep! You and Zim can play some other time!" She growled, daring them to make another sound. After a moment she turned and walked squeakily away, leaving the two in scared silence.

Silence which was naturally broken by Zim's mouth.

"Hah! Pathetic Dib, scared of your little sister?" He sneered.

Thirty seconds later found him on the side-walk in front of the house, disoriented and considerably more bashed up than he had been by the pillow fight. Dib was still being mangled inside, and from the sounds of it, it wasn't going well for him. Zim took only a moment to get used to moving around a probably broken rib before hurrying away from the scene. He didn't plan on walking home so injured, but he didn't want to summon the Voot Cruiser until he was far enough away to keep from turning the wrath of Gaz back on himself.
