At the beggining of the game, at one point you see a Stinker with a purple hat (the one by the purple spikes). Continue talking with him, and when he starts the dialogue when the Thwart runs away, start clicking the text that lets you end the conversation fast. As soon as it closes, run down to where the Thwart's going. Normally, he goes into a small area you can't see because of the high walls. If you go in there before him, then he won't go away and you're stuck. I think it's kinda funny
