Disclaimer: For all you who don't already know this, I don't own Invader Zim. I do own Teresa though. She is my made-up person so leave her alone! MINE! Please, by all means, draw her if you like, use her in your fanfics, just give credit where credit is due.





Chapter one: When Teresa Showed Up

"Son, daughter, you're new babysitter will be arriving shortly." Prof. Membrane said from the floating TV screen.

"Dad, I'm twelve now, I don't need a babysitter." Dib complained.

"Of course you are." His dad replied as the screen went blank.

Ever since the incident with breaking his arm chasing after Zim, Dib's dad thought it would be wise for the kids to have a baby sitter. Gaz had either scared them off or given them concussions by throwing things at their heads.

"I wonder how long this one will last." Gaz mumbled without looking up from her Game Slave.

There was a knock on the door and Dib went to answer it. When he opened the door he couldn't believe his eyes. There, standing before him, was what had to be the coolest looking babysitter ever. She had short purple hair that seemed to circle her face, in it were blue streaks. She had on a long, patch covered trench coat and zip up boots. Her shirt had the "Mysterious Mysteries" logo on it and she was wearing black shorts with nylons just like Gaz's.

She put what looked like a Game Slave in her pocket and smiled at Smiled at Dib. "My names Teresa." She said. Dib saw a glint of silver on her tongue. "I'm you're new sitter."

"Don't you mean baby sitter?" Dib asked.

"That's odd. You don't look like a baby to me." She laughed. "Unless you're inhuman."

Gaz walked up to Teresa as she walked inside. "You might last longer than the others." She grumbled.

"I like you're nylons." Teresa told Gaz. "You're the first I've seen to wear them except me."

Gaz shrugged her shoulders and walked into the kitchen.

"So," Dib said, "What is you're game plan for tonight?"

"What?"

"You know… dinner at 7, TV for an hour, and so on."

"Do I need to do that?"

"Well, everyone else did." Dib said a little confused.

Teresa adjusted her backpack. "Well, if they're plans had worked then I wouldn't be here." She said with a wink. "Actually this is my first sitting job. So where's my room? You're dad mentioned me staying here. He said it was the least her could do. I'm glad I can stay here too, my apartment complex just burnt down about a week ago."

"Oh, it's this way." Dib said leading her to the stairs. "Follow me."
