Author's Note: This is my first story; expect some mediocrity. Reviews will help me greatly. I will be crossing over the Rock Bottom episode of SpongeBob with no particular episode of Johnny Test.

I own neither Johnny Test nor SpongeBob SquarePants.

Johnny's alarm clock read 8:30 a.m., and that was when the alarm clock went off. Johnny, with a surge of energy as a result, jumped out of bed.

"It's Saturday!" he said, waking up Dukey who became happy knowing that it's Saturday.

"So what are we going to do in our time of no school, no homework, no Mr. Teacherman, and no Bumper?" Dukey asked.

"I never really planned what I was going to do this Saturday; I got nothing," Johnny replied.

The suggestion of watching TV came to Dukey's head. "Want to watch TV?"

"Sure. After breakfast."

Johnny and Dukey walked downstairs to eat breakfast he made himself: waffles. Dukey, in contrast, ate steak given by Johnny. Then they went to the living room.

Dukey grabbed the remote, turned on the TV, and flipped through some channels. There wasn't anything good on until he flipped to a cartoon that was okay. Dukey stopped flipping through channels and put the remote down.

Halfway through the cartoon, Johnny said, "It would be cool to just jump into a cartoon and be in it."

Dukey asked, "This cartoon that's on TV?"

"No, not this one. Maybe something else."

Dukey remembered something. "Hey, didn't we already do something like that? We once went into a Speed McCool movie where Speed McCool drove off a cliff in the ending and—"

"That's right!" Johnny interrupted. "We can just use my sisters' invention again, but the only difference is that we're not going into a Speed McCool movie; we're going into a cartoon instead." Johnny blindly grabbed a random DVD of a cartoon and the DVD player.

"Yeah, cool, but they aren't going to let you use it," Dukey said.

"To the lab!" Johnny said, pointing in the direction where the lab was while having the DVD in his other hand.

He just doesn't listen to me sometimes, Dukey thought as he followed Johnny.

"Aren't you excited to go to Glove World, Patrick?" asked SpongeBob.

"Yeah, I'm excited to go to Glove World!" replied Patrick with an enthusiastic tone.

SpongeBob and Patrick's intention was to go to Glove World and have fun there; however, what they didn't know was that they were on the wrong bus.

SpongeBob looked through the window of the bus. Then, an expression of skepticism formed on his face. "Hey, Patrick, I don't remember going in this direction.

Patrick looked through the window. "Uhhhhh … I don't see a difference."

"Are you sure about that? Because I don't think—"

All of a sudden, SpongeBob and Patrick felt themselves going down a 90-degree hill at a fast speed. It was fast enough to the point where they both flew off their seats and planted back-first onto the interior rear wall of the bus.

After a moment later, the rapid descending ceased, and the bus braked to a stop. The bus driver said, "You're at your destination."

SpongeBob and Patrick got off the bus. Both then realized that they were at the wrong location.

"This isn't right. Come on, SpongeBob, we got to get out of here," Patrick said, getting back on the bus. Then Patrick told the bus driver, "Get us out of here."

SpongeBob stared at the environment of Rock Bottom for a moment, then he walked towards the bus. But before he could get on, the bus took off, leaving SpongeBob behind. Patrick never realized this.

"No! Wait!" SpongeBob exclaimed as he waved his hands. But the bus kept going.

Johnny and Dukey went through the entrance of the lab that was an automatic metallic vertically sliding door and said, "I want to be in a cartoon!"

Susan and Mary looked at him, then Dukey, who was holding the DVD players in his paws.

Dukey said, "He wants to use a previous invention, that made him go into a Speed McCool movie, so he can go into a cartoon."

Johnny held out the DVD he was holding so Susan and Mary can see.

Neither of the sisters bothered to look at the DVD of the cartoon episode he wanted to be in. Instead, they both said, "Forget it, Johnny."

Johnny said, "I'll let you experiment on me right now if you will let me use your invention."

"Deal," Susan said.

Dukey face-palmed.

"Test this," Mary said, giving Johnny a beaker of clear liquid.

"Basically, it's something that will make you run faster," Susan said.

"And yes, we actually aren't going to give a complicated scientific explanation because you wouldn't understand what we'd be saying," Mary said.

Johnny drank the liquid. A moment later, all of his actions slowed to a extremely gradual pace, which was the opposite of what the sisters expected.

"We're going to need to work on that," Susan said.

"Is he going to change back?" Dukey asked with a little anxiety.

"In a few seconds, yes. We only gave him a micro-dosage. What was in that beaker was mostly just water," Mary replied.

Johnny reverted back to his normal speed. Almost immediately after he did, he said with enthusiasm, "Now let me use it!"

Dukey gave the DVD player and the DVD to Johnny's sisters, then they hooked up the DVD player to their invention within a matter of seconds.

"Okay, now all we need to do is insert the DVD into the player. Then, Johnny and Dukey is to put on the transport helmets…"

Susan looked at the DVD for a moment. "Wow, I'm surprised. Out of all the shows, you chose an episode of SpongeBob SquarePants?"

"Yeah, I just randomly picked that. I didn't care what cartoon I wanted to be in," Johnny responded.

"You know, I kind of want to go in with you guys," Mary said.

Susan looked at her. "Me too."

Susan and Mary got their own transport helmets and then Susan pressed the "Play" button on the remote.

The four were transported into Rock Bottom, and they saw an anxious SpongeBob in the distance.

"It's time for an adventure," Johnny said.
