How do I get past never land?

Goofy is in this level also, i wish i could tell u where but im just starting the 2nd level and havent committed the locations to memory yet. But basically it says if you rescue enough disney characters the heart meter goes up and breaks the illusions in the castle which will give u access to other levels. In the main hall of the fortress youll see that meter im referring too. Hope this helped a bit

If you beat Captain Hook you've basically beaten it. Just find more Disney characters and do side quests to unlock the next hallway. If you do the side quests as soon as you can you won't have to worry about this after bosses. Think of it like grinding as you'll also upgrade mickeys stats a bit by doing this.
