You've just taken on a werewolf, you feel like you can conqure anything even the horrible stomache that you are experiencing. You stumble along, resting your shoulder against several trees as you move onward. You're breathing heavily now and you have to rest again. Hey what was that?!
Something shiny catches your eyes. You bend down to examine it. Congratulations! you've just found 5 Galleons! some clumsy person must have dropped them or osmething bad happened to them...better not find out. You quickly grab the coins and run around the forest clutching you stomach until you notice the trees thinning out. You make it back to Hogwarts with your pockets weighed down with Galleons.
