Remember Dolphin Olympics, where you earnt points by gracefully backflipping around a lot? Well Miami Shark is sort of like that. Sort of.
In actual fact, Miami Shark is much better, because you get to eat things. Like people. And boats. And yachts. And helicopters. And passenger jets. And you can blow stuff up, too, and it chain-reacts and causes destruction on a level you'd barely even begin to comprehend without seeing it. Thus Miami Shark wins. Miami Shark always wins.
