"Danny!" Jazz yelled as they zipped through the air above Amnity park. "I have to study!"

"Oh," Danny looked back sheepishly, "sorry Jazz. This was the only way I could think of to burn energy."

"Where are we going?" Jazz asked, looking down warily.

"To get Sam and Tucker," Danny grinned.

"Why?" Jazz asked.

"The more people I can phase through things, the more energy I burn," he replied. Jazz slapped her forehead with her free hand.

"Why me?" she asked softly.

"Where did he go?" Sam asked. Jazz and Danny had disappeared, and while she could see into his room, she was convinced he wasn't there.

"Like I know," Tucker glared at her.

"Fine, we'd better go look for them before they get into trouble." She closed all her computer windows and opened her door.

"Mom! Dad! I'm going to hang out with Danny and Tucker," she said, and quickly shut her door. She flipped off her computer, and was just turning to leave when she heard her name.

"SAM! WATCH OUT!" Sam turned towards the voice, only to see Jazz Fenton rushing at her.

"Grab on!" Danny said. Wondering what was going on, she did as she was told, and then was rushed towards the wall...backwards. She had grabbed Jazz's arm backwards.

"Of course," She said drily to herself as she passed through the wall of her house.

Tucker was just walking out his front door when Danny called out to.

"Tucker!"

"Huh?" he had just enough time to look up and see Danny grab a hand full of the leather backpack he wore.

"Hey, pal," Danny said, "I need a favor."

"What?" Tucker yelped as he felt himself being lifted from the ground. They floated in silence for a few minutes until Sam called up to Danny.

"Do you realize how strange we must look?"

"Good idea," Danny said, turning them invisible, and phasing them through every dark office building in his path.

"Um," she continued, "I think we may have a problem." Danny looked down at her, and a large, grey vehicle came crashing down the street after them.

"The Fenton Family assault vehicle?" He gulped, "Why are mom and dad chasing us?"

"You're both gone from you're room, where they thought you both were, and they knew there was a ghost in the house. If you had that information to add together what conclusion would you come to?"

"Oh, right," Danny sighed.

"They're probably tracking us with that new invisibility inhibitor...that can show where invisible ghosts are." She realized the other three were staring at her. "What?" she asked. Danny dove through another office building. Should take them a while to get to the other side...especially if they had to backtrack. He backed out, and went in another direction, looking back to see his father trying to turn on a narrow street, and not succeeding very well.

"Uh, Danny," Tucker said before she could defend herself. "There's another problem." Danny looked ahead, and saw a row of large, ghost soldiers guarding their path. They all looked the same: heavy set, with large cylinders over their shoulders like a military gun line. Danny slowed and stopped several feet from them.

"Well, well, well," a voice said from behind he line, and a woman floated forward. Her skin looked to be a sickly, but very smooth green, her eyes glowed red...all making an interesting contrast with her blue dress and brown hair. Her overcoat, however, was red, and seemed to validate the whole strange ensemble. The most noticeable feature about her, though, was the large, wrap around belt with glowing green disks hanging from it. "So," she grinned cruelly, "I finally get to meet the infamous halfa."
