Just say the words Ocean Capture the Flag and Percy will take that planning right off your hands with a manic smile. That said, you can leave Capture the Flag to us. I'd say the main issue will be coming up with a less 'combative looking' way to stop people from getting the flags. Maybe doing something like touch or flag football...
Ok, but what counts as smiling for Wolverine? Because not a frown could count as a smile.
