I have this idea based on Brainulator9's blog post, but this is my own.

  1. Complete I, Zombie Too using only Buckethead Zombies.
  2. Crash the game 1 time (Done by Minh)
  3. Get 100 flags in Survival: Endless (Done by Minh)
  4. Win Last Stand without using ANY Melon-pults, Gatling Peas, Cattails and Winter Melons and its imitated form
  5. Complete Bobsled Bonanza without ANY Jalapenos and its imitated form
  6. Find a way to make Imitater Upgrade Plants (like Tammttg)

If you've done one or more of this please tell me by commenting!
