A/N: It's been a while and while Halloween is over, MV Mania isn't stopping the celebrations yet! Here's a new MV for a familiar song of 4 ghost-busting group.

ToonSchool Music Video Mania

Ghostbusters

Spotlights shine on the ToonSchool Music Video Mania stage which is decked out in Halloween decorations. A crash of thunder and flash of thunder, and a wolf's howl occur and the cheer of the audience bellows through as Tony, Phineas, and Ferb stand on stage, dressed up for Halloween.

"Hey, everybody! It's been a long while, but once again, we're back with ToonSchool Music Video Mania! I'm Phineas and this is Ferb," Phineas introduces them to the audience, and Ferb waves at them.

"And I'm Tony Clark!" Tony says as the audience applauded. "And Happy Halloween everyone!"

"Yeah it's the scariest time of the year, and I hope everyone in the audience has something good planned for the night of spooks, even despite certain recent events," Phineas says with the audience giving loud cheers.

"And all you kind kids be sure to practice social distancing for whatever you do this Halloween," Tony.

"We will," the kids in the audience say in unison.

"And we have a smashing MV for you to enjoy this Old Hallow's Eve," Ferb says. "The first of which being a modern and ToonSchool twist on a classic holiday carol."

"Care to describe it, Phineas? " Tony asks his co-host. "

"You bet," Phineas says as he turns on the nearby TV screen. "Ghostbusters is known as the biggest hit film of the 1980s. And it's eponymous theme song is unforgettable too. Sung by Ray Parker Jr., the song debuted during summer 1984 after the movie release and eventually made it's way to #1 on the Billboard list. Since then, it has had managed to become a cult favorite for Halloween."

"And this year the Phineas & Ferb gang teamed up with my good friend Danny Fenton, aka Danny Phantom along with his family, hometown friends Sam and Tucker, and multiple members of his rogue's gallery for a smashing new video," Tony adds. "Which we have here today!"

"So without further delay, here's me & Ferb and our friends teaming up with Danny Phantom, his family, friends, and enemies on a cover of Ghostbusters," Phineas says to the audience, who applaud as Ferb quickly grabs the remote and switches the screen's channel to the music video.

In an apartment of the Krusty Towers, Gloria yawns as she lies down on the couch while staring at the television's static screen in a bored expression. Just then, Gus enters with a bowl of popcorn in hand when he notices his friend on the couch and frowns at this.

"How long are you going to loaf around on the sofa?" he asks.

"Until I have the energy to stand up. You know I spent the whole day training and schooling! I'm not cut out to do classes!" Gloria complains, which Gus sighs at this.

"At least try to switch the channels for me. The remote is not far away from where you are right now."

He then takes the said device and taps a button many times to surf through the channels. However, he stops at a news program where a panicked Chet Ubetcha is in front of some burning buildings.

"This is Chet Ubetcha of Toon Town News Network, with breaking news!" he says as a bunch of familiar ghosts was causing trouble. "Toon Town is under a spectral siege! Ghosts, poltergeists, and spirits from all over are wreaking havoc all over the city!"

Just then, Skulker swoops down at Chet, who ducks, with the ghost hunter barely missing him.

"We have the Flynn-Fletcher boys Phineas and Ferb and their motley crew of friends trying to keep these ghosts at bay, using replicas of the famous Proton Packs and Traps used by a certain ghost hunting team."

"Thanks, Chet," says Phineas as he and Ferb approach while their friends (Candace, Isabella, Baljeet, Buford, and the FireSide Girls), continued battling the ghosts. "As cool as these replicas are, this is our first tango with actual ghosts. And we're a little… overwhelmed."

Just then, Ember McClain swoops down to them and blasts some loud notes from her guitar, forcing the three to take cover.

"We need people who are experts at battling ghosts to help us."

"But in this day and time, who we gonna call?" Ferb asks.

"Only one group," Phineas replies as he picks up his phone and dials a number.

Elsewhere, at Fenton Works, Team Phantom and the Fenton family are just lounging around and relaxing: Tucker and Danielle are playing a video game, Danny and Sam are watching them, Jazz is reading a book, and Jack and Maddie, are tinkering with a Fenton Blaster. Suddenly, an alarm sounds in the lab, catching everyone's attention, and they all get determined looks on their faces as the song starts.

After a brief montage of Danny and Danielle transforming, and the others strapping up to head out, the scene cuts to them leaving Fenton works: Danny and Danielle flying ahead, with Jazz, Sam, and Tucker following in the Spectre Speeder, and Jack and Maddie coming behind them in the Fenton RV. Danny then kicked off the song.

Danny: If there's something strange

In your neighborhood

Who you gonna call?

Team Phantom: Ghostbusters!

Team Phantom specs and zooms through the spooky streets, blasting and capturing random specters along the way.

Danielle: If there's something weird

And it don't look good

Who you gonna call?

Team Phantom: Ghostbusters!

As Team Phantom continues to make their way to the scene, Phineas, Ferb, and their crew continue holding off the former's rogue gallery.

Phineas & Danny: I ain't afraid of no ghost

Ferb & Jack: I ain't afraid of no ghost

Finally, Team Phantom arrives on the scene and starts assisting the others in rounding up the malevolent spirits. Danny tackles Skulker to the ground and kicks him in the face, while his dad blasts the spectral hunter with a Fenton Bazooka, and then sucks him into a Fenton Thermos.

Sam & Isabella: If you're seeing things

Running through your head

Who can you call?

Everyone: Ghostbusters!

Isabella dodges guitar blasts from Ember, while Sam, armed with the Fenton Ghost Gauntlets, and grabs the rocker ghost from behind while tossing Isabella another Thermos, which the lead Fireside Girl sucks Ember into.

Tucker & Baljeet: An invisible man

Sleeping in your bed, oh

Who you gonna call?

Everyone: Ghostbusters!

Nicholai Technus chases down Baljeet but is then struck down by the Fenton Booo-merang, which then returns to a smug Tucker, who sucks him into his own Thermos.

Everyone: I ain't afraid of no ghost

I ain't afraid of no ghost

Buford attempts to restrain Desiree with his Proton Pack, but she dodges the attack and picks him up by the pack. However, she is knocked out of the air by Jazz, who is sporting the Fenton Ecto-Skeleton. She Catches

Jazz & Buford: Who you gonna call?

Everyone: Ghostbusters!

Jazz: If you're all alone

Buford: Pick up the phone

Both: And call

Everyone: Ghostbusters!

Candace, meanwhile, finds herself annoyed by Youngblood, finding him even more annoying than her own brothers. But just then, Danielle swoops in and blasts the child ghost away from Candace. After recovering and realizing who hit him, Youngblood slyly tries to flirt with the Ghost girl, but she responds by sucking him into a Thermos.

Danielle & Candace: I ain't afraid of no ghosts

Mmm, I hear it likes the girls

I ain't afraid of no ghost

And lastly, the other Fireside Girls fInd themselves cornered by Johnny 13 and Kitty and Penelope Spectra and Bertrand, who all manage to dodge their ward-off attacks. But before the four ghosts can strike, Maddie jumps in front of the girls and blasts the four away with her Fenton Wrist Rays. Before any of them can recover, she then sucks all four into her own Thermos

Danny: Yeah, yeah, yeah, yeah

Who you gonna call?

Everyone: Ghostbusters!

Maddie: Mmm, if you have a dose of a

Freaky ghost, baby

Fireside Girls: You better call

Everyone: Ghostbusters!

The two teams then continue to work together to round up the remaining ghosts, with Danny eventually capturing the last one, the Box Ghost.

Ferb: Aw!

Lemme tell ya somethin'

Bustin' makes me feel good

I ain't afraid…

As the song ends, the two teams stand victorious as Chet Ubetcha rejoins them.

"Wow, that was incredible! And just like that folks, the crisis is over thanks to the efforts of Team Phantom and Team Flynn-Fletcher. So what do you all have to say about this?"

"Well, It was all in the teamwork, Chet," Danny said. "I mean, Phineas and Ferb, did a decent job in holding these guys at bay."

"Yeah, but you guys are the true heroes around here!" Phineas pointed out. "You all did the heavy lifting."

"Indeed, but I guess now the city's got two teams to call now," Ferb quotes.

"Team Phantom/Flynn-Fletcher!," both teams said in unison.

"Talk about unity. And that'll be all for this breaking news! until next time, I'm Chet Ubetcha from Toon Town News Network, saying 'Boos to you!'"

As the news coverage ends, Gus and Gloria are still staring at the television with their eyes widened in a few seconds of silence.

"So..." Gloria speaks up. "ToonSchool antics?"

"ToonSchool antics."

With that, Gus turns off the TV, ending the MV.

Back on the MV Mania stage, the audience cheers loudly as Tony, Phineas, and Ferb stand there, mikes in hand.

"Whoa, now that was awesome!" Tony says with a grin.

"Crazy, scary, and action-packed!," Ferb adds.

"Like any other video we put out there!," Phineas says. "Anyhow, that's all the MV Mania we have for you today!"

"But keep on the lookout for other treats from Runner and Nash," Ferb says. "Until then, this is Ferb…"

"And Phineas…"

"And Tony, wishing you all a Happy Halloween and…"

"SIGNING OUT!," they all said in unison.

With that, the three hosts wave at the cheering audience as thunder crashes, lightning flashes, a wolf howls, and the Halloween decorations and lights glow ominously in the background.
