Hey, guys. I'm back with another crossover fanfic. This one was requested a while back by JackieTheFox, about a crossover with Zootopia and Sing, the two best furry movies of last year. Sorry it took a while to get this started, but it's here, now. Without further ado, here's the long awaited Zootopia-Sing crossover.

It was another bright day in Zootopia. Judy Hopps, already up and at them in her uniform, hopped down the hallway to the apartment door of her best friend and partner, Nick Wilde. Judy knocked on the door fast, eager to get the day started.

"Nick! Come on! I'm ready to make the world a better place!" said Judy.

Inside, Nick was in a rude awakening by the sound of Judy's knocking. Nick groaned, and picked himself up from his bed. Nick got his suit on, drank some coffee, and walked outside to his happy, hopping bunny.

"Morning, Carrots." said Nick, rubbing the remaining sleep out of his eyes.

"Hey, Slick!" said Judy, beaming. "Come on! We gotta hustle! Chief Bogo said he's got a special case just for us!"

"Oh, goody. I can hardly wait to see what Chief Buffalo-butt has in store for us." said Nick. "How much coffee did you have this morning by the way, Fluff?"

"Actually, about three cups. I couldn't help it. I was just so excited for today's case! Come on, I said hustle!" said Judy, already making a head start down the hall.

Nick grinned, shook his head, and ran to catch up with his bunny. The two hopped in the police car, and drove to work, sharing a bag of donuts Judy picked up, along the way.

When they arrived at the ZPD, Judy ran past the front desk, waving hello to Clawhauser, then barged into the bullpen. Nick simply walked inside smoothly, and sat beside his giddy partner. Chief Bogo walked in, and the officers started rooting for their awesome boss.

"Alright, alright! Shut it!" Bogo ordered.

"I've got a couple of new items on the docket. First, Wolford! Happy birthday!"

Everyone cheered for Wolford, while his partner, Fangmeyer, howled alongside him.

"Number two!" Bogo called.

"We have a new case that needs solving. This one's not in Zootopia. It's actually, in fact, Sing City."

"Sing City? That certainly takes originality to a brand new level." Nick remarked, in his usual sly and humorous manner. The others officers giggled.

"Cork it, Wilde!" Bogo snapped. "You'll be happy to know that this case will be involving you and Hopps, here."

"Say what?" Nick said, his smile immediately dropped.

"Correct." Bogo grinned.

"I mentioned this to your partner yesterday. Lately, there have been a string of robberies in this city. The local police department already have a prime suspect, but they have already called in a few agents from our precinct to help with the investigation. I'm assigning Clawhauser to join you and Hopps on this case. Officer Mabel will be filling in for Ben, in the mean while. You three will be flying there around noon to meet the chief of the Sing City Police Department. Now, here's the rest of the assignments."

As Bogo listed the remaining assignments, Nick leaned to whisper to his giddy partner.

"This is what's got you giddy all morning? Also, why Clawhauser?" whispered Nick.

"The chief thinks it'll be good for him to get back into field work for a change. Ben's so excited, himself." said Judy.

"I've heard a lot about this city. There's animals that live there that are hardly seen or never seen at all in Zootopia. It's got some great places to visit, too. I know we need to focus on the case, but I wouldn't mind seeing a few of the sights. Especially one place. Moon theater."

"Carrots? The thing is, I can't fly." said Nick, a little ashamed.

"What?!" Judy smirked.

"Yep. Fear of heights. Ever since I was a kid. Don't laugh." said Nick.

"No prob, Nick." Judy said, biting her lip to stop herself from laughing.

"You think it would be okay to bring Finnick along with us? Having an extra set of eyes and muscle, even if he's not an officer, might help." said Nick.

"We can take that up with the chief when the meeting's over." said Judy.

...

Buster Moon woke up in the drawer that was his bedroom. Now, with the theater rebuilt, and it was getting more money than ever, he really needed to get a place of his own. But, old habits were hard to break. Buster turned off his alarm clock, brushed his teeth, changed into his suit, and jumped out of the drawer.

"Let's go to work." said Buster, closing the drawer behind him.

Buster hopped into his chair and said, "Cue the crazy lizard."

On said cue, Buster's iguana assistant, Ms. Crawly, walked in with coffee.

"Good morning, Mr. Moon." she said.

"Top of the morning to you, Ms. Crawly." said Buster.

"Here's your coffee, sir." Ms. Crawly said, handing Buster the cup.

Buster looked into the cup, but saw no coffee.

"Uh, where's the coffee, miss?" he said.

"Oh, I got a little thirsty on the way up the stairs, again." said Ms. Crawly. "Oh, the gang's all hear early today, sir."

"Everybody? Already?" said Buster.

"Yep. Johnny, Rosita, Gunter, Meena, and Ash." said Ms. Crawly.

"Well, let's not keep them waiting a minute longer, Ms. Crawly." said Buster.

Buster and Ms. Crawly walked down to the first floor, and greeted everyone on the stage. Of course, when Buster got closer, he noticed the sad and worried looks on their faces.

"Morning, gang. Why the long faces?" said Buster.

"We're all just on edge from the robberies, Mr. Moon." said Rosita. "I worry about my kids a lot. Me and Norman had to walk the first 25 of them to school, this morning. The babies are with their grandma, Norman's mom."

"There are even some rumors that my dad is behind all of them." said Johnny. "Except, he can't be. Dad's in jail, with his parole due in a couple more weeks."

"Yeah, my mom isn't too keen for me in going out after dark with any of my friends from school, for now." said Meena.

"Okay, everyone. Just remain calm." said Buster Moon.

"This city may have been hit with the biggest wave of theft in years, but we are not gonna let a bunch of crooks, whoever they are, think that they can just come in here, and take control our town, by taking what's not theirs. As an old friend of mine once said, we are not gonna let them see that get to us. So, that's why I just got a grand idea for a show. A musical that promotes the themes and morals against crime. So, who's with me?"

The group cheered at Buster's idea, showing they were all in agreement.

"That's the spirit! Now, let's get our brains storming, and get to work on how we want this show to be, folks." said Buster.

...

Noon came, and everyone was rehearsing for the new show. Buster and Ms. Crawly were overlooking Buster's turn to rehearse on the piano, when the sound of large doors bang open, and a voice yelling out Buster's name.

"BUSTER!"

Everyone turned to see Eddie barge into the theater, panting.

"Eddie?! You okay? Did someone try to rob you?!" said Buster, rushing to his best friend.

"No, it's not that. I'm fine." said Eddie. "Buster, you gotta hear this. You are not gonna believe who's showing up at the airport, today!"

...

"Please remain seated, everyone. We're about to land in Sing City in five minutes." said the cheetah stewardess.

"Finally!" Nick let out a sigh of relief, taking off the blindfold he wore for the entire ride over.

"Nick, if you really wanted to forget about your fear of flying, you should just do what Clawhauser and Finnick are doing." Judy said, pointing to Clawhauser.

The cheetah officer and fennec fox were sleeping soundly in the row across from where they were sitting. Clawhauser had his earbuds in, listening to 'Try Everything' on his iPod, drooling on himself. Finnick had his earphones, listening to rock music, and unlike Clawhauser, snoring loudly.

"Now, there are faces of bliss." said Judy.

"Whatever you say, Carrots. I'll feel better when we touch land." said Nick.

Soon, the plane arrived at the airport. Everyone began to grab their belongings and step off the plane.

"Guys. Guys, we're here!" Judy said, shaking the sleeping Clawhauser and Finnick, to no avail.

Nick took off the earbuds and headphones, then shouted; "Hey, sleeping beauties! Nap time's over!"

"Wah! No, Mommy! I didn't take any suckers from your candy dish!" said Clawhauser. "Oh, it was only just a dream."

"Come on, Spotty. We're at Sing City." said Nick.

"Dang, Nick! Try getting me up with a megaphone next time." Finnick complained.

Nick, Judy, Clawhauser, and Finnick collected their things, and made their way off the plane. When they reached the airport, Nick could swear he was hearing someone calling his name. When he heard it again, louder this time, Nick looked around to see where it was coming.

That's when he spotted a familiar koala, jumping up and down, waving his arms to get his attention. Next to him was a tall sheep, just simply waving hello.

"Buster! Eddie!"

Nick ran over to the two mammals, who became more ecstatic when he greeted them in a friendly hug.

"Well, I'll be." Finnick smiled, as he and the others walked over to where Nick was.

"Nick, how do you know these guys?" asked Judy.

"Oh, Carrots. I should introduce you." said Nick.

"Judy, Ben. This is Buster Moon, owner of Moon Theater. That's Eddie, the grandson of Nana Noodleman, the opera singer. Buster, Eddie. This is Judy Hopps, the first rabbit police officer in Zootopia. Just like how I'm the first fox police officer in Zootopia. That's Benjamin Clawhauser, another great officer. You guys remember Finnick, right?"

"'Sup, guys." said Finnick.

"Good to see you again, Finny. It's also a real pleasure to meet you, as well, officer Hopps and Clawhauser." said Buster.

"You too, Mr. Moon. I've heard so much about your theater. I've also heard so much about your grandmother, Eddie." said Judy.

"So, don't keep us in suspense, Nick. How do really know these guys?" asked Benjamin.

"We, uh... sort of worked together on a few hustles when they came to Zootopia for a time. That was back when he and Finnick first started hustling, and Buster and Eddie were in college." said Nick.

"Oh, it was all good with us, Nick. Sure, we scammed folks out of their dough. But, being a business entrepreneur myself at the time, we had some good times, though. I've been meaning to go back and make amends to the mammals I scammed, though." said Buster. "So, what brings you guys to Sing City?"

"How about you show us your theater first, then we'll talk?" said Nick.

"Nick, we need to report to the police station for the case, first." said Judy.

"It'll be real quick, Carrots. Besides, you want to see the Moon Theater yourself, right?" said Nick.

"Oh, okay. You got me there. But, real quick." said Judy.

The group made their way out of the airport, and then followed Buster down the road that led to the theater.

...

Meanwhile, a hooded figure was watching the group leave the airport, behind the corner of a wall. The figure pulled out a radio from his pocket, and pressed.

"Boss, the eagle has landed." said the figure.

"They're here. Excellent." said the voice on the other end of the radio. "Keep your eye on them. Let me know if they get too close on our trail."

"Roger that." said the figure.

"Oh, and Duke, don't screw it up." said the voice.

The figure, Duke Weaselton, gulped. "Understood, sir."

Duke took off his hood, hid the radio back in the pocket of his hoodie, and left before anyone could see him.

Well, guys. That's it for this chapter. I'll post the next one as soon as I can. Hope you guys are enjoying this so far.
