Phineas and The Ferb Tones were performing their latest hit, "Shake Your Tail" on Teeth TV. Kablam's Henry and June host The New Video Hour, where they play the latest music videos and talk about them.

"And that was Phineas and The Ferb Tones with their latest hit, "Shake Your Tail"." said June on the TV.

"They will be performing their hit songs Saturday night at Madison Square Garden. So get your tickets now, and it's going to be a great concert." Henry said on the TV.

The Celestian Alliance were in New York for the charity costume party at RBTV. They are now in the new Equestria Program at Sky High where they go around the world and learn about magic. Stitch missed The Midnight Society, but they'll always be in their hearts. Pleakley came in with Phineas and The Ferb-Tones.

"Juumba," Pleakley said, "We have a guest."

Juumba opened the door and it was Phineas and The Ferb-Tones. They came to the ship to rehearse after Buford filled the tank with BBQ sauce again.

Buford: I found some on the road.

"Come on dudes," Zach said, "you can practice in here."

"Can you play us your latest song please?" Pinkie asked.

"Sure Pinkie Pie," Phineas answered.

"Have you met before Pinkie?" Zach asked.

"Yes Zachy," Pinkie replied, "We met during our end of summer festival last year where Tucker accidentally turned us into humans."

Phineas and The Ferb-Tones set up their instruments and started playing.

"We just got the day to get ready and it times to ignite the light. Shake your tail cause were here to have a party tonight!" they sang.

"Oh my god, that's the worse song I'd ever heard!" An orange experiment insulted as he came through the window.

"Experiment 322 a.k.a Heckler, he insults people." Lilo explained, "Heckler, shouldn't you be at RBTV?"

"Yesary Potato nose," "But Rocky and Bullwinkle didn't want me to mess up the decor for the stupid costume party tonight.

"Heckler, apologize now!" Twilight shouted.

"Well, Twilight you need to spark your bad breath." Heckler insulted.

Then he saw the new Celestian Alliance.

"So you're the new Celestian Alliance." Heckler said to them, "Where's the old one, did they run away because their werewolves?"

"No, they have school and we're only doing this for the semester," Will explained

"Look at those glasses," Heckler said to Ethan as he removed his glasses "they feel like they've been boxed!"

"And big guy, lose the black you look like a werewolf!" Heckler insulted to Warren.

"Why you!" Warren yelled as he flamed up so hard that he accidentally started the fire alarm.

Heckler slipped and dropped Ethan's glasses. Then Applejack came and snatched the glasses.

Later, the kids were drying off. "Oh my," 3PO said as he gave them more towels, "You kids are going to slip."

"Thanks, Threepio," Magenta said.

"Really," Rarity complained, "I don't want the fire alarm to ruin such great hair for the costume party."

"Rarity," Ethan asked, "Do you still have those costumes from the Re-Halloween Party?"

"Of course darling," Rarity answered, "I hate tossing out good costumes."

"Meega gonna party again." Stitch shouted.

Phineas had his disco costumes from Disco Minature Golfing Queen. There the band decided to do that.

Stitch, Angel, Felix, Sparky, and Sample decided not to wear a costume since he's an alien. There the team placed their costumes on and headed off for the party.
