Airball

"Now you're really in trouble," said the evil wizard. "I'm going to turn you into an air ball and send you to my castle with over 250 rooms to look for the spell book that can give you clues on how to turn back into a human. It's not as easy as it sounds, because you as an air ball have a slow leak and have to jump on an air pump in some rooms to stay inflated. Watch out, because if you inflate too much, you'll burst! Next, if you're lucky enough to find the book in these rooms, you'll need to pick up the items I left behind: Crosses, tinned beans, a Buddha, a dragon statue, a pumpkin, a hip flask and even crates that you'll need to overcome treacherous obstacles! This is your only chance of survival," he cackles. "Sounds easy," you say to the evil wizard with a laugh. "Oh, is it?" he sneers. "Well, I've also put spikes in these rooms that will take your breath away, and killer pads on the floor. You have no chance of success... Hee! Hee! Hee!"
