Lemony Snicket: A Series of Unfortunate Events Cheats

When you are trying to get the two last soot piles, on the right
side of the screen there will be a little crawl space that Sunny can
fit in. Go in it, and you will find last two soot piles. After that,
talk two Count Olaf and he will give you another mission.

Aim your Peppermint Popper closely in front of her feet. Once it is aimed properly, do not stop firing. This should work for all of the Leeches.
