In level 10, there are jars that you throw and if they land right-side up, you get money. Well,Here is an easier way of getting money from it. Grab a jar and toss it. If it doesn't land right-side up and a little guy will pop out and bounce around the room. When he pops out, DO NOT KILL HIM! While he is away from where he can hurt you, grab the jar and throw it again. Then a coin will come out. Kill the little dude and repeat the process. P.S.:This doesn't work on EVERY try.
