It had been a few weeks since the adventure in Camp Everwood and Mike was eating lunch at Pop's Diner.

"Nice to have ya back, Mike." Pops smiled to the tomboy.

"Good to be back, Pops." Mike smiled back.

"How was camping?" Pops asked.

"It was all right," Mike replied. "It was nice to be with my girlfriend and Nicktropolis friends."

Cindy hummed as she came to the diner and took out a paper. "Does this place have Rubens?" she then asked.

"Yes, we do, we just added them to the menu now." Pops replied.

"Okay, I'll take one of those and a grilled cheese sandwich to go." Cindy then said.

"Coming right up." Pops told her before going behind the kitchen.

"Hi, Mike, welcome back to the city." Cindy told the tomboy.

"Thanks, Cindy," Mike replied. "You know, I've been thinking about having another adventure with my Nicktoon friends."

"Uh, you just got back from there..." Cindy reminded her.

"No, no, like a real adventure with them." Mike explained.

"Oh, I get you now." Cindy said.

"Really?" Mike asked.

"I dunno..." Cindy shrugged. "I'm just trying to kill time... I think it's a good idea though since you never see them that much."

"So, what're you up to?" Mike asked.

"I might've made Penn mad..." Cindy looked away.

"What did you do to make him get mad?" Penn asked.

"I don't wanna talk about it..." Cindy looked away.

"Oh... Oooookay?" Mike replied.

"Trust me, you don't wanna know..." Cindy warned. "Now I'll just go away into the background and you'll never see me again."

"Here you are, Cindy." Pops said as he handed her the food.

"Thanks, Pops." Cindy replied.

"I miss her already." Mike sighed.

"Who, Lil?" Cindy guessed.

Mike nodded in response.

"Oh, Mike, it's okay, it's not like you're away from each other forever." Cindy said as she went to give Penn his and her lunches.

Suddenly, Skarr's car zipped by and it was being followed by Grim, Billy, and Mandy.

"And it looks like we're on an episode of COPS." Cindy commented.

"We better follow them." Mike suggested.

"Did you say we?" Cindy replied.

Mike grabbed Cindy's hand and ran with her to see what was going on.

"Whoa!" Cindy yelped as she was dragged behind.

Grim, Billy, and Mandy were still chasing Skarr, even slicing a squirrel in half.

"I'm okay!" The squirrel replied.

"This calls for track #6!" Skarr called out as he took out a CD called 'Escape Mix' and he put it into his car radio.

Grim soon came beside the man with a glare. "You can't outrun Death!"

"That's why I have turbo!" Skarr replied before pushing a button to drive off faster.

"You're not doing this right." Mandy said as she grabbed the scythe.

"Hey!" Grim glared.

"I'm driving."

"Girls can't drive, everyone knows that!"

Mike soon took a skateboard from someone like in Back to the Future and began to skate up with Cindy wobbling behind her. "Hey, guys, what's going on here?" she then asked.

"Hi, Mike, hi, Cindy!" Billy waved stupidly.

"I don't feel so good." Cindy moaned.

"Gas station!" Mike warned Grim, Billy, and Mandy.

Mandy's eyes widened while Billy screamed as Madame Foster was about to pump her gas until they crashed into the tank which made the tank end up on Billy's head.

"Totally not my fault." Grim said.

"Hot Fudge truck!" Cindy cried out.

Luckily, they all ducked underneath the truck before they could hit it or get stuck in the hot fudge.

"Fireworks...?" Mike and Cindy asked weakly.

The man behind the fireworks stand then ran off as they were about to crash into his stand. Grim, Billy, and Mandy had fireworks on their faces and finally caught up to Skarr and the former general grinned and pressed the oil slick button.

"What does he think this is, the Wacky Races?!" Mike deadpanned.

Ashlyn and Danielle soon zipped over in their go-karts in their aunt and uncle's old racing outfits in slight offense.

The oil then caught on fire thanks to the scythe.

"At least there wasn't a missile." Cindy commented.

"Time for the big guns!" Skarr grinned as he pushed the next button to unleash heat-seeking missiles. "Or should I say missiles?"

Mike then glared at Cindy.

"I should've kept my mouth shut." Cindy chuckled nervously.

Skarr soon drove off the end of a dock and went under the water to turn his car into a submarine. Grim, Billy, Mandy, Mike, and Cindy came to the dock as Skarr went under the sea.

"I wonder what this one does?" Skarr wondered as he then pressed a button which shot a laser right through him. "Oh, now I remember..."

"So, what happens now?" Cindy asked.

The missile soon came on the dock behind them which wheeled over the fireworks stand with the hot fudge truck.

There was then a flame trail coming right up by them, and then...

KABOOM!

They were all now covered in smoke and soot.

"I'm okay, I think..." Cindy coughed.

"Now what?" Mike asked.

"Well, I think I better go home..." Cindy backed up. "Uncle Penn's probably home from his new job by now."

"Hmm... Cindy, call me crazy, but I feel like something bad is going to happen to Grim, Billy, and Mandy." Mike said.

"What makes you say that?" Cindy asked.

"My sixth sense." Mike replied.

"You wanna go with them, don't you?" Cindy asked.

"Yeah, and if you're just gonna go home and be scared, I'll see you later." Mike said before going off.

"Ugh, peer pressure..." Cindy groaned and then ended up following Mike as the trio went to Billy's house.

"I can't believe you two scared off another one," Grim snarled at the kids as he plopped down on the couch next to Billy as he sat upside down. "I've got a caller to meet."

"They're dead, Grim," Mandy replied. "They'll turn up sooner or later."

Then as if on cue, the doorbell rang Mandy opened the door it was Irwin in a bear costume.

"Your Huggy Bear is here to maul you with his love, yo." Irwin flirted.

"Not now, Irwin." Mandy replied before slamming the door in his face.

Mike and Cindy looked disturbed.

"Hey, guys..." Mandy muttered as she came into the living room and then did a double take as Irwin was somehow in the house and was sitting on the couch much to her confusion.

"My job could be on the line!" Grim scolded Billy and Mandy. "I have a reputation to uphold!"

"Jobs don't have to be forever, Grim," Billy soothed. "My dad starts a new job almost every week."

"So does my Uncle Penn." Cindy added.

"Billy's right, Grim," Harold said as he came in the room with the newspaper and some toilet paper. "I've been fired before, and it's not bad. In fact, I get fired all the time! Why today, I just got fired from the Freckle Burger for eating all of the paper cups!" he then burped one up in Grim's face.

"What was that, dear?!" Gladys called out.

"Uh, nothing, Gladys!" Harold called back nervously.

"Are you sure?" Gladys came into the room. "I could've sworn-"

"Uh... Me no speak-a your language." Harold replied.

"If you lost that job at Freckle Burger..." Gladys snarled as she took out a harpoon.

Harold babbled and soon ran off.

"HAROLD!" Gladys soon chased down her husband.

"The point is, you kids can't be mixing up my business with your pleasure, I can't be losing clients like this." Grim then continued.

"You're the only one who cares." Mandy replied.

"Guys, I think we have company." Cindy said as she looked out the window to see strange creatures marching outside the house.

"Could be trouble," Mike warned the others. "Be on your toes."

Cindy soon looked down to her feet and wiggled them slightly as she didn't wear shoes. Even Billy's cat seemed concerned as she looked up from her saucer of milk.

"Hey, Grim," Billy spoke up. "How come you got moving zits?"

"Huh?" Grim took a look.

"Aaaugh!" Irwin panicked. "It's the man!"

The creatures in SWAT uniforms knocked the door down and shined the light on the others' faces.

"Grim Reaper, you're under arrest for your misuse of your powers and dereliction of duty." The creature told the skeleton.

"He said 'duty'." Billy giggled.

"I was right, looks like we're gonna need some help." Mike said as she pulled out her communicator.

"Mike, this is your chance to have an adventure with your friends in Nicktropolis." Cindy suggested.

"Wow, thank you, Cindy." Mike replied.

"No problem, but hurry though." Cindy nodded.

Mike took out her communicator and quickly called her friends in Nicktropolis to help out.

Penn soon came through the front door of Billy's house. "Hey, Cindy, your mom changed the WiFi password again, and-" he then looked around. "What's going on here?"

The creature then sprayed knock-out gas in his face.

"Night, night..." Penn said before passing out.

Cindy tried to get out of the way only for Penn to fall on top of her. The others were then taken to the Underworld as Grim was put on trial. Luckily, Mike sent out a signal to get help from her friends at Nicktropolis.

"Ow, ow, ow, ow!" Drell winced in pain as Maroot pinched her son's ear.

"Come on, Drell, you promised me you'd be a good boy and come to the court with me for the Grim Reaper." Maroot grumbled as she tugged Drell by his ear.

"Fine, fine." Drell complained.

"I hope my friends got the signal." Mike hoped.
