But what was he doing in the water? Raquayza lives in the ozone, doesn't he?
Edit: Wait, I just thought about something. Ok, Fox zips through the air and gets shot down by the Halberd. During the tussle, Raquayza wakes up and gets shot in to the lake. He wakes up to see Fox's ship and Diddy standing next to it. This prompts Raquayza to give Diddy a stern talking to about flying ships when Fox intervenes.
