Best thing to do is to keep playing levels up to round 85-90 (preferably on expert maps so as to rake in the monkey money) and if necessary (it's optional) you can do the no escape mission what with the M.O.A.Bs, B.F.B's and Z.O.M.G's if done for consecutive hours(not too much) you should get it in no time.
