So it took me about 2 weeks of having this awesome app to solve all the levels on easy, medium, and hard, with the exception of "Skippy's Revenge.  It was one of the additional ones you needed to purchase.  I have been playing this level non stop now for 4 days and can't get past level 14 of 18.  It tells me to search the internet for clues on how to solve it.  I have searched and am still clueless.  Anyone have any ideas?
