This is another crossover, written at about the same time as the other.
Disclaimer: I do not own Danny Phantom or The Cry of the Icemark.
Danny and Dani rushed to get to school on time. Danny's family had adopted Dani after she was stabilized, buying the 'cousins' story, and despite the utter chaos of the Fenton family, she enjoyed it. They had had just caught the Box Ghost, but that was enough to nearly make them late. They rushed through Lancer's classroom's door just as the bell rang.
"Just in time, Ms. Fenton, Mr. Fenton. Try to keep it that way, if not early."
"Yes, sir." They mumbled, knowing that was not at all possible.
Class proceeded. Surprisingly, there weren't any ghost attacks in the middle of class, so Dani and Dani were both actually able to finish all their work in class instead of as homework.
All was normal. Which was not normal. Danny's life, after all, could not possibly remain normal for long. Just as Dani's couldn't.
As he entered second period, he felt something slip over his head and heard a voice say,
"Time out!"
Danny turned around to see Clockwork. He glanced around to see that everyone else was frozen in time except him and Dani.
Then he started to worry.
"Why are you here, Clockwork? Has HE escaped?
"No, Daniel, he is still locked tight within the thermos, and he will stay that way for a while. No, but, your assistance is required elsewhere. In another dimension. Will you do it?"
Danny hesitated. He thought for a minute. He looked at Dani who shrugged, saying she would if he did. "How badly is it needed?"
"Quite needed."
He thought some more. He knew that Clockwork would not force him to do it. But...
"I'll do it."
