What plants do you expect to see in Far Future? Here's mine:

  • Chomper: He's in the coding for the game, so I feel if they were to add any plant, it'd be him.
  • Starfruit: His design was seen before, so like I said before, it's likely he'll appear again.
  • Magnet-shroom: Since the new world takes place in the future, the zombies are probably going to wear metal things as protection. Magnet-shroom would help a ton if this is the case.
That's really all I can think of, tell me what you think...
