I love snow peas because:

  • They, in effect, do as much damage a repeater
  • They look cute (especially in pvz1)
  • They, in effect are like a Torchwood, except they also, in effect, do twice the damage to zombies from non-peashooter plants as well.
  • They are unlocked way earlier than a Torchwood in pvz 1
  • They are a lot cheaper than a winter melon

And finally

  • They actually do direct damage unlike a Torchwood.

I love snow peas so much that they were the only plant I bought with real money in pvz2.
