As THP says, PvZ1 randomizes zombies, the only time I can think of where zombies are at least partially fixed in a wave-based level (AKA non-vasebreaker) is Column, where huge waves send specified amounts of Gargs and certain other waves always spam Jacks or Ladders.

However, I have an understanding of the system PvZ1 uses to randomize zombies, so I can estimate how many zombies, and what types they would be, are LIKELY to appear in waves in PvZ1.
