Today Daniel Fenton was visiting a museum. Funny saying how he normally didn't like them that much, after all last time he went to one it turned out that Tucker was reincarnation of a pharaoh with a ghost minion bent on world domination. If Danny remembered correctly, the museum was about some big shot musician named... Leo... No, Billy John... No, no, no, Billy Joe Cobra! Yes, that was it. Only problem was that no matter what Danny did, the host would charge him for it. Well, that and the fact that his ghost sense was going crazy, but he couldn't see any ghosts.

His family had decided to take a vacation out into the middle of nowhere so that Danny could get away from all the hubbub about him and Phantom being one and the same. What would hurt the most though, is being away from Sam... oh and Tucker too. Ever since he revealed his "big secret" people had been flocking around him, and his parents insisted on "helping" him catch all of the ghosts. One of the upsides was that he was excused from class whenever he wanted, and he was quite popular now. Paulina had been practically trampling everyone else to get close to Danny. However... Danny had been getting more and more homesick for the past, when he had two identities. And so Maddie Fenton decided to take the family on a road trip! Whoop. de. doo.

Danny crossed his arms for the millionth time. He looked around at the "freaky tiki" room (or so he thought it was called) and spotted the brown-haired teenager tour guide. The guide -Spencer?- was talking to himself. Again. Danny paused and watched for a little bit, Spencer looked like he was in an argument with the air... That's it. That's the ghost. Danny shuffled closer and feigned that he was checking out this musicians' guitar.

"Billy!" An exasperated comment came from Spencer, "Yeah I know, but check out the lives you're touching -even more!" he paused, then said slightly angry, "Yeah I know what happened last time!" Another pause, "But look at the cash!" Spencer got a triumphant look in his eyes, "Yes, yes, I can fix your jet from that party a while ago." another pause, "Of course it sounds awesome! It is!" yet another pause, "Deal then?" He held out his hand and suddenly it looked like he was picked up and shaken like a ragdoll, "Billy! Let me get back to the fans! Mon- ...er... your fans await!"

Spencer sighed and turned back to the tour, as if nothing had happened. And, well, the group didn't seem to mind that he was talking to himself. Danny shrugged then jumped back when the guitar floated and played a few cords.

Spencer ran over and snatched the instrument from the air, and whispered a quiet "Billy!" then turn back and nervously laughed, "Pretty good effects, was testing them for... my new movie." He thought for a moment, "The House Attacks! Yeah, that wasn't a very good idea so it's cancelled." The group all murmured something about his special effects and continued to wander around the area.

Danny watched as Spencer whisper-yelled at the air, Danny facepalmed, then walked over. "You're talking to a ghost right?"

Spencer stopped instantly and looked over, "g-ghost? N-no it's just... my invisible friend!" He high-fived the air.

Danny lifted an eyebrow, "Oh, well, because I happen to be an expert on ghosts."

"Oh, you don't say..." Spencer eyed Danny, "What was your name again?"

"Danny Fenton." Danny replied and turned back around, he was going to solve this mystery. Danny pulled out the Fenton phones. maybe these'll help. He stuck them in, they help Sam and Tuck hear him, so he could possibly use them to hear this ghost here. The ghost sense was starting to drive Danny crazy, he wouldn't be able to sleep tonight if he didn't fix this.

"What's with the ice breath?" A voice suddenly came through the phones, really close.

"It's called ghost sense." Danny replied, resisting the urge to jump. He hated it when ghosts used their invisibility all the time. Pretty impressive that he could hide his voice too.

"Woah! homebod! He heard me!" The voice ran over into Spencer's direction and Danny turned the way the voice went.

"Wait- can you see him?" Spencer asked nervously

"Nah, but I'd appreciate it if i could. I want to see if this guy's one of my enemies."

"Enemies?" Spencer looked up to the right.

"I've never seen you before..." The voice said, then gasped, "Maybe he's a fan of The Cobra!"

"Cobra? Billy Joe Cobra?" Danny asked

Another gasp, "Yo! Spencer! He is a fan!" Danny gestured around him and Billy quickly replied, "Oh. Right! He's such a fan he came to the museum!"

Danny facepalmed, "Just show yourself."

"Show myself? Oh!" a ring floated in midair, and floated to Danny, "Put this on."

"Why?" Danny hesitantly took it.

"It's some of my gear! You can see me if you put it on!"

Danny eyed where he thought the ghost was, and put the ring on his pinky finger, and suddenly a blue-tinged see-through figure appeared in his face. Danny jumped back, "Dude! Why the face?"

Billy laughed, "That's always fun!" He then floated over to Danny, "Why aren't you running in fear?"

Danny's turn to laugh, "I'm a half-ghost! I see you guys all the time!" Danny glanced over at Spencer, who was mirroring Billy's open-mouth expression. "What?"

"Half-ghost?" Spencer ran over

"Y-yeah, never heard of Danny Phantom?"

Billy looked deep in thought, then snapped, "Oh! I got it! ...No, I don't got it."

"I thought I was world-famous. Huh. YES!" Danny jumped up, "One place in the world I can just hang out!"

"Yeah, that's great, but, uh, what's your favorite single I've made?" Billy flew back into Danny's face.

"I'm not a fan, I've never heard of you!" Danny peeled Billy's fingers off his face.

"N-not a fan?" Billy floated back, and suddenly blue-green... glop came out of his eyes in the form of... tears?

Spencer rolled his eyes, "Billy, I bet he meant no harm."

"B-but" Billy turned to Spencer, soaking Danny in the stuff by accident.

"Wha-what is this?" Danny watched as the stuff soaked into his skin.

"Just some ecto, why?" Billy replied

"Well, I-I don't think my ghost half likes it very much." Suddenly, Danny's blue rings forcefully turned him into his ghost form, "yeaah, this might be a problem."

Spencer blinked a few times at Danny as he floated, "What?" Danny retorted

"That was... AWESOME! How can I still see you?! I'm not wearing any of your gear!" Spencer threw his hands up in the air.

"What? You mean you have to wear Billy's gear to see him?" Danny looked around, the tour group disappeared. "Hey, where'd they go?" Danny landed on the ground.

"I'm sure that Jeeves took care of-"

Spencer got cut off as Billy shouted and flew over to Danny, "OH! HOW CAN YOU DO THAT?"

"Do... what?" Danny asked

"Stand. On. GROUND!" if Billy's mouth could get wider, it would have "I wanna try!" Billy set down on the floor and sunk through, "Aw man, this sucks." Danny watched as Billy sunk through the floor.

"Does, he, uh, always act like this?" Danny pointed to where Billy disappeared.

"Yup, pretty much." Spencer took a breath, "He should be back in a while, after he figures out he actually can't stand on the ground."

"O-okay then." Danny strode over to Spencer, and a silence started to form.

"So," Spencer broke the silence before it got awkward, "are you going to turn back human? My crazy sister hasn't asked for her money in a while so she should be coming soon to get it. Not sure she'd like the fact of a ghost being here." Spencer took a step back, "You know, if people really can see you without your stuff."

"Oh, right, sure." Danny willed himself to be human, and his rings appeared faintly, then disappeared. He was still Phantom. "Okay, that doesn't normally happen." Danny tried again, no response. "Okay, what really was that stuff Billy cried?"

"It was his ecto! Can you not change back?" Spencer asked, his voice raising in concern.

Danny shrugged, "I guess not."

"Hey! Where's my 50-50 money Spencer? There were plenty of people I had to kick out!" A young girl walked into the room.

"See ya later!" Danny gasped, then phased through the floor.
