Kirby Mystery Dungeon

It was the perfect day for a nap. Kirby went to a good windy spot to sleep for a couple of hours, dreaming peacefully about his friends and, of course, food. However, Kirby gets mysteriously thrown into another world (again) and he has to find his way out of there, while some of the inhabitants there try to take advantage of him as he's too trusting. Will he ever be able to get back to his own world alone, or will he be stuck there for eternity (or until his friends find him after a bit of time)? And what are these new Copy Abilities that he mysteriously gained?
