Level 59 looks horrendous!!

[Very impressed]

Hi,

Been reading this forum from a far.  Decided to try the riddle...  Now completely addicted....  Now completely suck....Very impressed that someone managed to get to level 72.  So I felt I had to join.

I'm stuck on level 18. Is anybody able to help, before my computer goes out the window?
