You slide the hat on your head, and while it seems to be rather inanimate, suddenly a voice greets you as if appearing out of nowhere.

You are not a Hogwarts student… Yet you possess a sharp mind and a keen wit. You are well on your way to solving the riddle.

Casting the Anti-Odour Charm has the immediate effect of eliminating the stink of the Shack, but it does nothing to get rid of the rotten food or the rats that scurry about this way and that. Best make sure that you don’t get in their way as things could become rather unpleasant for you then.

The stove seems to be a good place to look, and the Bubble Head Charm is a good idea because there is no knowing what horrible stench might greet you if you decide to investigate further by looking inside the oven. Turning each of the knobs counter-clockwise each in turn, you can feel one wiggle and jiggle slightly and smoke appears from the oven.

Well done! You know what you need to do now.
