I went around and collected the sweet things. Lollipop, syrup, tooth, in that order. Then I went back to the hole, pressed e a bunch which popped up dialogue, then after trying that for a bit I pressed q, which started the submission dialogue. Then I moved over in my inventory to the lollipop, selected it, selected "lower efficiently", finished the cut-scene and then I couldn't move. I could shift in my inventory but I couldn't move. If you want more information I have a video clip. I just need to trim and upload it first.
