Zim entered the lab, a blueprint in his hand and GIR at his heels.

"This new device will finally help me conquer the world!" he said with triumph. He unrolled the blueprint, showing his device to GIR. "I'll teleport some super-weapons from the Tallest's ship to my lab, and I'll get my victory over these filthy humans!"

GIR looked at Zim curiously. "And then we can make muffins, right?" he asked. Zim sighed. "Yes, then we'll make some muffins," he lied. It was common for Zim to lie to his faithful yet dim-witted robo-servant to get him to do his bidding.

GIR grinned and began gathering parts around the lab to make Zim's teleporter device. Zim watched him, looking forward to the day when he would take over Earth. Buildings would crumble, people would be vaporized, oh, the glory of it all! Then, and only then, the Tallest would take him seriously, and he'd become a true invader!

Meanwhile, on another planet, Twilight Sparkle was sleeping peacefully in her bed when she heard a knock on her door. The purple unicorn lazily rolled out of bed. She'd stayed up very late last night reading a book about other worlds. She walked past Spike curled up on the floor and opened the door to see Pinkie Pie, eagerly holding a plate of cupcakes.

"Rise and shine, Twilight!" she said. Twilight peered outside groggily. The sun was indeed shining. "Hi, Pinkie. What's with the cupcakes?" she asked. Pinkie Pie smiled. "They're for you, silly! These reeaally have a kick in them, so you can get up and embrace the day!" Pinkie Pie's cheerful attitude caused her to spread happiness to all of Ponyville, much to the chagrin of the grumpier residents.

"Thanks, but I'll do without them," Twilight replied. "I just want to sleep in for a couple more minutes." She yawned and closed the door, going back to bed.

"Okay then!" Pinkie cheerfully yelled through the door. She trotted back to the bakery with the cupcakes in tow. "I guess I'll save them for later," she said to herself. She dropped off the cupcakes at the bakery and walked away to spread more infectious smiles.

Back on Earth, a large-headed human named Dib was preparing for a secret mission. He knew that Zim was an alien, but no one believed him and he needed proof. He grabbed his camera and snuck over to Zim's house. The house was rather unusual, as the front lawn was filled with lawn gnomes. Zim really stinks at disguises, Dib thought. He peered through the window and saw GIR in the kitchen, attempting to make muffins. Luckily, GIR wasn't wearing his dog suit that he used to disguise himself. Snap! Dib took a picture. Once he showed this to the public, he could stop Zim once and for all. Now to get inside and take a picture of Zim...

Zim was down in his lab, marveling at how fast GIR had built the teleporter. He underestimated what GIR would do for muffins. "I suppose I should start it now," he said, typing the coordinates for the Tallest's ship into the teleporter. Suddenly, Zim heard GIR scream. The outburst made Zim accidentally change the coordinates unknowingly. "GIR! Be quiet, I'm trying to work!" He didn't bother to see why GIR was screaming. He was too close to his goal to care about anything else. "Computer! Initiate teleportation," he ordered. Immediately, the teleporter started whirring and flashing. It got louder and louder. With one final grinding noise...

The cupcakes were gone! Pinkie Pie had only been out for ten minutes and they were gone! "How mysterious..." she said. She thought it strange that the plate was missing, too. Who would steal a plate?

She ran back to Twilight Sparkle's house. "Twi! The cupcakes just disappeared!" she shouted before Twilight opened the door. The unicorn was still very tired. "Pinkie, you probably just ate them and forgot..."

"Forget? Me? I never forget!" Pinkie tapped her head with her hoof. Twilight rolled her eyes. "Fine, Pinkie. Let me have five minutes to get ready and we'll look for your muffins..."

"Cupcakes," she corrected.

"Whatever."

Dib was in Zim's living room, looking for any sort of secret switch to Zim's lab. He'd taken care of GIR by hitting him with his camera. "Where's that stupid switch?" he murmured, kicking a table in frustration. The table folded back to reveal a secret entrance. "Oh, there it is." He walked down the passageway to Zim's lab.

Zim was holding a plate of cupcakes when Dib entered. "Give up, Zim! I have pictures of your robot and the lab!" he yelled. Zim looked up from the plate of cupcakes. "Dib! You must have interfered!"

"What are you talking about?"

"Don't play dumber-than-you-already-are, human! You ruined my plan again!"

Dib cocked his head to one side. "Really? Is it that easy to stop you that I do it by accident?" he mused. Zim angrily threw one of the cupcakes at him, knocking him to the floor. "Computer! Take the human away!" A robotic arm shot out from the ceiling, taking Dib's camera and crushing it. It then grabbed Dib and threw him out.

Zim studied the cupcakes closely. They looked strange. Nothing like any cupcakes he'd ever seen.

"Computer," he said. "Identify where these came from. I asked for super-weapons, not baked goods." A screen flashed on, showing a series of numbers and a colorful planet. "Location: Equestria," the computer said. "A planet populated mainly by horse-like creatures, such as unicorns, pegasi, and ponies."

Zim laughed. "Ponies? Are they vicious and evil?"

"Not particularly," the computer responded. Zim thought about that. If it was peaceful, why not take that over instead of Earth?

"Prepare the voot cruiser. I'm going to visit this... Equestria."
