Pirates and Zombies

"Pish, it's all the same," Percy replied. "Zombies and deep water. It's not a match made in heaven is it? I mean, what if I fell in? I can't swim. I'd sink and drown."

"You need to be able to breathe before you can drown," said Dreth. "The worst you'd face is a long walk to land, or possibly being nibbled by fish. I suppose we could lower the anchor and pull you up, but I don't know if I'd want to waste that much time."

"I could breathe if I wanted to," retorted Percy. "I'm just out of practice." He opened his mouth and attempted to inhale, making a strange croaking sound. A moment later he exhaled, producing a wheezing noise and a puff of dust. "See?"

"You call that breathing?" scoffed the little devil. "I can do better than that, and I don't have lungs even." 

"Was breathing so." Percy flapped his arms about. "It was invigorating too. I feel all pumped up and oxygenated. Good for what ails you, breathing is."
