This is my first cross-over. So please review...

I do not own Adventure Time and The Amazing World of Gumball.

Gumball and Darwin in the Land of Ooo

A story of pure adventure and magic...

Gumball and Darwin in the land of Ooo – Chapter 1: A Time-Machine for a Science Project

"So what are we going to do for science project this year?" Darwin asked Gumball.

"How about we ask Anais? She's the 'sciency' one," Gumball replied.

"No need for that," Darwin said rubbing his head with his fins, "I already have an idea. We're going to make a – time-machine! Brilliant idea, isn't it?"

"And who's gonna help us make it?"

"Anais!" Darwin said enthusiastically.

"Eeexaactly"

*Anais' room*

Gumball: Anais! You gotta help us. We're your brothers.

Anais: I help you with your science project every year. How about you actually think for yourself this time? Also, building a time-machine is theoretically impossible.

Darwin: oh *disappointed*

Gumball: Come on, Darwin, we'll make our own time-machine. Hmph! We'll see who's right.

They walk out of the room. "Guess we have to make the time-machine ourselves," Gumball said firmly.

"But how?" Darwin asked.

"I don't know. You have any idea?" Gumball asked.

"Are we trying to travel forward or backward in time?" Darwin asked.

"Forward, of course! Don't you want to see the future cities with flying cars and advanced machines?!" Gumball answered.

"Yeah of course!"

"Then what are we waiting for? Let's get to work!" Gumball said excitedly.

"But we still don't know how to make one."

"They say you can travel through time in a wormhole! But… we still don't know how to make one,"

"Let's go to Anais then!"

"She isn't gonna help us… Darwin?"

Darwin ditched Gumball and was already running up the stairs to Anais' room. Gumball chased after him.

"Anais please! You gotta help us create a wormhole!" Darwin pleaded.

"Look who came back!" Anais said cool-ly as Gumball caught up to Darwin and came into the room.

"Look Anais, it's very important for my science project – also I want to see flying cars." Gumball said.

"Looks like I gotta deal with them the dumb way," Anais thought. "There is one way you could create a wormhole." Gumball and Darwin's face cheered up in a second. "Get all the clocks and watches in the house and put them in the oven," Anais instructed, "Then heat it up for 5 minutes. This will bend time and you can go to the future!" Hmph! Once they realize that they can't travel through time, they'll learn their lesson and leave me alone, Anais thought.

"Alright!" Gumball said happily, "Thanks Anais." The dumb brother quickly headed downstairs to follow Anais' directions. Anais laughed quietly at her brothers' stupidity.

"Alright, that's all the clocks in the house," Darwin said with his fins full of clocks and watches.

"Put it in the oven, then," Gumball said opening the microwave door. Darwin did what he was told.

Anais couldn't hold in her curiosity. She went downstairs and walked to the kitchen to see what's going on. "Hehehe. I can't believe that they are really doing this," she muttered to herself.

"Hey Anais! You are here to watch us go off?" Gumball asked nicely.

"Yeah. Pffft. Sure, Gumball," Anais said controlling her laughter, "Hold the oven while it heats up. The oven will carry you to another dimension."

"Oh ok," Darwin said setting the timer and holding the oven with Gumball.

The clocks sizzled inside the oven and angry sparks of electricity started to come out, but the two brothers were too excited to notice that. Anais was 100% sure that the oven will bust and she'd get in a lot of trouble, but this stupidity was totally worth watching. She quickly took out a camera and started to record it. "This is going to hit a million views on the internet," she thought.

"Gumball," Darwin called, concerned, "Don't you think the oven is getting a little hot?"

The surface of the oven grew red hot from the boiling clocks inside.

"It's alright, Darwin. I think it's because we are getting closer to the wormhole," Gumball said determined to see the future.

Then suddenly a bright flash of light came out of the oven, blinding Anais. She heard Gumball and Darwin screaming in a distant. "Gumball! Darwin! You alright?!" Anais called out in anxiety. After a second later, the flash was gone – and so were Gumball and Darwin.

Anais just stood there with her jaws dropped. Did her dumb idea about time-travelling just worked?

Is it good so far? Or bad starting? Review to let me know!

I'll update the next chapter soon, so don't forget to follow...
