 Danny s ghost fighting has been causing him to be in a pickle, because he has to study for a test and not doing so has got him a D. Sam suggests that he should do extra credit by doing a report on the purple back gorilla, plus, Tucker put Danny s schedule in his PDA. But now Danny is in more trouble because a ghost hunter (whos a ghost) named Skulker has spotted Danny and is trying to capture him, and just as soon as Danny met his doom, Skulker spotted Tucker s PDA and attached it to his armor. He gains more power, but now he keeps flying off to a new location. Danny s very lucky, but how long will it last?
