li in a bubble

so I have finally made it to the body and I have found Li and the little boy. I sing Li's song and the extended version but nothing , I have done things in all forms and nothing. I want my friend back how do we reunite?

If I understand you correctly, you're missing something you need to get him out. More specifically, four things. Wander around in the Body for a while, you can't do anything here yet. You've got exactly the right idea, you just can't do it yet.

PiSketch is correct. You need to venture to all (accessible) parts of the Body to find the four things.

Also, you know that you double-posted this, right?
