Mystery Dungeon Ghosts

Dash, after school, ends up following Danny back to his house only to be caught up in a beam of light that hits both him and Danny.
What world did they end up in?
What are these strange creatures?
How will they get back?
And will Danny be able to keep his secret?
Find out~

I do not own Danny Phantom or Pokemon. They belong to their respectful owners. ^^
And the pokemon Danny will be, is one that I sort of found in another story on fanfiction that will not be finished, sadly. ;-; So, if the owner wishes for me to take out this delta pokemon, i shall just use its regular form. The name of said author is thephantomcat, if you are this person and wish for me to take the pokemon out, i shall. I just think that it would be cool to have a delta or two in this story. ^^ (There is a slight difference in the pokemon, but the general idea of it came from that story.)
And there will be another delta within it as well. ^^
