Everyone who saw the film saw that crazy portal world when Hiro and Baymax went to save Abigail, right? With all the cloud stuff that looked like the clouds from "Cloudy with a Chance of Meatballs"... What do you think is in there?

When Hiro started to face back towards the portal, a bit to the left was a cloud thing that was surging around all strange, and it looked like a portal, too. And I could have sworn that I saw it one or two other times (in different places). It had me really thinking about what kind of stuff is in there and what it leads to. Even if it's just grasping at straws, what do you guys think about it? Sequel material, or what?
