Invader Zim and Gravity Falls

I came up with this when I was really bored. I'll have a series on this. So here's the story thingy...
Dib laughed excitedly. "Finally! I can transport Zim back to whatever planet he's from!"
"Oh, go away," Gaz said sullenly.
"Gaz! We don't have to worry about Zim anymore!" Dib said happily. Suddenly, a Classic Poop spilled, and bits of electricity were everywhere. "AHH!"
At Zim's house...
"Do something PRO- hey, what was that?" Zim asked GIR, who was eating tuna.
"MOOSE!" GIR yelled.
"Not that.. like an electric-" Zim couldn't finish before they were immediately transported.
Gravity Falls, Oregon.
"Beep bop boop!"
"Mabel, PLEASE stop that." Dipper complained. The forest was silent. Then, a loud thump.
"Mabel, did you hear that?" I asked nervously.
"Yeah, it was over there." Mabel pointed to the trees. Dipper tipped his hat, and he and Mabel sneaked over.
"Ow!"
Hmph. I'll KILL you, Dib."
"OW! MY BACK!"
"YAY! I HURT SO BAD!"
"What the-?" Dipper asked, entering the clearing. 4, strange people stood in the center.
"Whoa.... Is this in the book?" Mabel asked.
"No...." Dipper mumbled, flipping through the book.
one boy groggily opened an eye. He looks us over "What the-?"
"Dipper?" Mabel asked, then noticed the green-skinned kid. Flippy black hair on the top of his head, and he blinked his purple eyes open. "DIB! I knew IT WAS YOU!"
"I wonder..." Dipper asked. "This isn't zombies, ghosts, or gnomes.."
"Wait, you believe in the paranormal?" Dib asked.
"Yeah, we fought gnomes," Dipper said. quietly.
"I wish I did..." Aspen said
"Zim's an alien," Dib said, walking to the Dipper.
"OH MY GOSH ITS SO CUTE!" Mabel ran to the little green dog and squeezed him.
"Oooh!" GIR said.
Suddenly, Gideon stepped through the trees. "And I'll take over with my cuteness!" (not really) he chirped.
"GIR! SHOW THEM YOUR MIGHTY ROBOT FORM!" Zim commanded.
Waddles walked to the rubber piggy. "Halp." he thought.
"Derp," the piggy thought.
"It's all your fault, Dib." Gaz snarled.
"You know, you can stay at the Mystery Shack. It's our Grunkle Stan's place." Mabel offered.
"Sure," Dib said.
"Fine," Gaz grumbled.
"Zim can set base there! Zim is a genius!" Zim said to himself.
"OOH!" GIR squealed.
They started home.
"So, I think we'll have to share a room..." Aspen mused. "I still get my spot."
"The room should be big enough," Dipper said.
I"ll work on it later, g2g
