The problem with penguins is that Northrend cooking somehow managed to ignore them. I think there needs to be an additional branch of Pandaren cooking to be the equivalent of Guangdong's tendency to cook anything.
I agree, so much opportunity here. They created a mini-game full of various critters you go around killing, but for some inexplicable reason you can't throw them into a pot afterwards. Albeit that'd be rather disturbing with some of them, and I can't imagine the clockwork gnome tastes very good. I'd eat the turtle though, crab looks tasty, and why not brew a sporebat lager?
