Splatoon Side order

I honestly can't wait for side order to come out for Splatoon, I have so many theory's and thoughts. I wonder where everyone has gone and why there is coral everywhere... if everyone is gone then why are we there with pearl and marina, are we putting ourselves in danger? It might be a dream, but what why would off the hook be there? Who are we even fighting this time? It's really exiting I really hope it comes out sometime this year. What are your thoughts about it? :)
