The Phantom Pegasus

That same mysterious unicorn that had sent the Phantom trio to Equestria found herself searching the Ghost Zone with a scowl. She had a feeling for some peculiar reason that just leaving those three in that world wouldn't be enough to hold them back- no, she needed to add another ripple to make sure they stayed where they were.

As such, she would trick some foolish ghost into going to Equestria. It had to be someone stupid and repetitive- someone who would keep coming back to bother them. After five minutes of searching, she had found the perfect ghost for the job...

"I am the Box Ghost! Fear me and my cubical containers of evil and torture!"

Flipping around, she saw some idiotic looking fat blue ghost attempting to scare her. A few boxes floated by him. She gave a blank look at him. "Aren't you scared?" he asked, puzzled by her stoic look. The pony rolled her eyes.

"Of course not, you dolt. However...I may be able to use you to help me...scare some people. Possibly a lot of people."

The Box Ghost didn't even need a second to think about it. "I'm in. For I am the Box Ghost! And I will infuse terror into hapless people!" he proclaimed.

"I got well enough that you want to scare people. However, there's a catch. Danny Phantom and his friends are in this...place that I put them in to distract them and keep them out of the way. They may be still equipped with some ghost catching device. I can't have you captured, so I need you to show up from time to time to scare masses and distract them, then flee when the time is right. Do a good job and I may be able to reward you very well..." she trailed off. She had no actual intention on giving the Box Ghost a thing for his trouble.

Box Ghost was immediately enraptured by the plan. "Easy enough. Where are they?"

"You'll see." That was the only thing she said before she had a portal pop up behind the ghost she had just recruited, then bucked him into it before he had a chance to react.

Right before the trio and their new pony friends were about to take off, Rarity spotted something odd behind Sam. "Sam, what's that thing behind you on the ground?" she asked, confounded by yet another strange device. Everyone looked back and saw the Fenton thermos and a chicken from Fluttershy's coop standing on it innocently. Sam gasped and picked it up with her mouth carefully, placing it before her.

"It's a...soup thermos."

"Strange looking for one..." Applejack murmured. Sam shook her head.

"Oh- of course not. Hehe. Hey Danny, do you mind taking it?"

"Sure-"

"There's two other strange things that two of Fluttershy's chickens are carrying- I'm assuming they're yours." Applejack said. Again all three had to look around them to see some chickens with cell phones in their mouths. Sam slowly approached one of the chickens and tried to coax it to drop the cell phone, which it did eventually. The other chicken got bored of the object and dropped it.

"Danny, looks like our cell phones. Man, we're really lucky to have all this stuff with us. I don't know if it'll take calls here, though, but still."

"You guys sure have a lot of strange gadgets from that world you're from." Rainbow Dash said, curiously looking at them. Danny shrugged.

"I'll just leave this stuff by Fluttershy's house and pick it up before we leave. It'll be kind of awkward to try to fly and have all this stuff jammed in your mouth. Anyhow, um, let's get started!" he said, trying to avoid further questions. The other ponies shrugged.

"Alright," Rainbow Dash said, "we're gonna have fun teaching you guys!"

After an hour had passed, the trio made a little progress. Danny managed to learn to flap his wings correctly and fast enough to float off the ground a little and was beginning to gain a little height. He still needed some practice maintaining his form in the air. Tucker made a few rocks move around with his magic. Sam did fine like the other two- earth ponies didn't have magic or could fly, but she was good at trying to get apples down from Applejack's trees. Applejack had also taught her that earth ponies had a special connection to nature in spite of not having the ability to fly or use magic, and since Sam enjoyed gardening, she could hardly object.

Danny made a mental note to pick up the thermos and cell phones right before they headed back and followed Applejack, Rarity, and Rainbow Dash to Twilight Sparkle's library. They stopped at Rarity's on the way, because said unicorn offered to stop to get them a bag to carry all their strange things. Upon getting to the library, Tucker paused a moment. His horn glowed. "For...for some reason, I feel like I need to check my PDA..." he said, surprised. Rarity shrugged.

"Go ahead, darling. Sometimes unicorn magic works by itself and in different ways. Try looking. We'll be inside." she said, the three other ponies going inside. Tucker pulled out his PDA and turned it on. Immediately it began to buzz- on the screen it said 'Foley Household'. With some nervousness and wonder how the phone was managing to get calls from Amity Park, they answered it.

"Hello?" Tucker asked.

"Oh, sweetheart! Thank goodness you're okay! Where are you and your friends?"

All three paled and shared a look. This was going to be awkward to explain...

Back in Amity Park, when it reached dinner time and none of the teens had returned home and Tucker didn't answer his PDA nor was Sam or Danny picking up their phones, all the parents began to worry. Eventually they got to Tucker's house to try to figure out where to look- and were about to try calling the police when Tucker finally answered the PDA. Tucker's mom eagerly answered to Tucker's 'hello' and all the adults crowded around the phone to hear their children.

"Where are you guys?" Maddie cut in.

"Oh- are all of you guys there?" Danny asked, paranoid. He was answered in a second.

"Yep! Where are you all? We're worried sick!" Jack bellowed.

"My parents, too?" Sam asked, almost cringing with the expected answer.

"Of course, darling!" her mom's voice rang. The trio all simultaneously grimaced. This was going to be the most awkward conversation ever.

"I-I don't think you guys would quite believe us...um, trust us, we're fine. It's a ghost's doing...let us explain about it so you can try to get her first! You'd believe us better if you found her." Tucker said.

All the parents were baffled and scared. Where on earth could they be? A ghost?

"Tell us what happened, start to finish, no matter how hard it is to believe." Maddie said. She and her husband were ghost hunters; there really wasn't anything that could really shock them much, right?

There was a pause. "Tucker, I know you're trying to save energy on the PDA, but maybe this would work better if we took one picture to help back up our story..."

"Are you sure? This is going to be so, so weird..."

"Tuck, it doesn't matter if we show them a picture or not, it's going to be awkward, period. Plus we need Danny's parents to help find the ghost; and it'll calm our parents kind of if they know where they are..."

Two groans escaped the boys.

"Fine...um, guys..." Danny took over. "Listen. We're gonna take a picture with Tucker's PDA of...where we are and send it to you. We need you to just stay silent and just listen to us before you ask questions. We'll explain everything."

After a moment, the parents agreed. "Hold on..." Tucker said. There was the squeaking of a door. "Hey, can one of you ponies take a picture of us? Our parents want to know where we are, and we need photographic proof..."

The parents listening became puzzled by the mention of ponies.

"Um, okay..." An unknown voice that was really Twilight Sparkle came. "How do I use this thing?"

"Here, I'll go to the menu for it...alright, I set it up. All you have to do is press this button on it."

"This one?"

"Yeah. We'll say when."

"Can we be in the picture, too? Please?"

A cheerful voice that belonged to Pinkie Pie came through.

"Um, sure, Pinkie."

"Yay!"

"Alright, are you guys ready?"

"Yeah, Twilight.

"Alright. One...two...three!"

"Thanks...oh! We left the phone on!" Tucker cried, surprised the parents heard everything that went on.

"I didn't know your PDA could do both!" Sam said, surprised. There was some hoofs stepping- making everyone on the other line raise an eyebrow. Were there really ponies in the background? In reality, Danny, Sam, and Tucker were just moving to a more private spot. A moment later, they received a photo that was astounding.

A bunch of unusually colored ponies, pegasi, and unicorns in a photo with strange markings on each of their backs- what struck them most was that the three center ponies looked liked pony versions of their children. They already had so many questions buzzing through them, but remembered the promise they had made to keep quiet through it.

"You're probably shocked by what we sent you, but let us explain..." For the next ten minutes, the trio explained the whole story to their astounded folks on the other side- the ghost unicorn that had sent them there, how they were ponies in this new world- pegasus, unicorn, and earth- and the new friends who had offered to help them and about Princess Celestia, who they knew little about at the moment but said that their pony friends said that she might be able to help. After it all, there was a long silence. Danny murmured to his friends briefly.

"How do you think they're taking it?" Danny mumbled, beginning to feel uneasy.

"You guys..." Maddie's voice came in. "We're shocked, that's for sure. But we'll do anything to make sure you all get back here safely. Mr. Fenton and I will search high and low for the ghost you described."

"And we'll offer a reward for anyone who might have any information about this ghost." Sam's father said. "No one does this to our daughter and gets away with it."

"Or our kids at all. Tucker, sweetie, you said you were trying to save the battery on your PDA. If it's okay with the other parents, we're gonna ask you guys to shut it off for now. Keep in contact every so often, though. Danny, Sam, do you guys still have your cell phones?"

"Yes- we just found them right before we started 'Pony 101'."

"If Tucker's PDA goes out, use those."

"Okay."

"Danny..." Jack's voice came, "You and your friends be careful. We're just glad you're all safe."

"And make sure to say thank you to the ponies who offered to help you."

"We will...bye, guys!" Sam said. Danny and Tucker both offered their 'byes' and then turned off the PDA. Danny sighed in relief.

"Glad that's over. C'mon." he said, and they all walked out from their private spot. The rest were waiting.

"How'd it go?" Twilight Sparkled asked. Sam exhaled.

"It was...awkward, but our parents said they're gonna look for the ghost unicorn that did this. Danny's parents are ghost hunters, so that should help."

"That's good...and wait, I remember you said 'ghost' earlier, not to mention Danny's parents are ghost hunters. A ghost unicorn?" Rarity asked. Danny nodded.

"Yeah. Ghosts are common in our world. Hard to believe, but true. You actually probably don't believe us, and we can't force you to and can see why you wouldn't."

Fluttershy couldn't help but give an 'eep' at the mention of ghosts. Pinkie Pie joyfully disregarded the semi-serious moment and grinned broadly.

"Anyhow, the party I set up is ready! Come with me, everypony!" she proclaimed, dashing out the door. Everypony laughed, thankful for the moment's ease, and followed her out. Danny remembered something.

"Oh yeah, guys, thanks helping us." he said. Applejack grinned.

"You're welcome. Always glad to help."

Right after they all left, Spike came out from a room he was napping in. He raised an eyebrow. "Somehow I felt like I missed a lot..." He paused and spied a letter on the table. He walked up and read it.

"Dear Spike-

Pinkie Pie decided to throw a party at Sugarcube Corner. I didn't know when you'd wake up, but if you find this, you're free to come and have fun.

-Twilight Sparkle."

Spike grinned. "Party? Hope it's not girly. But why the heck not!" he said, rushing out the door.
